'''Google Earth''' es un programa informático similar a un [[Sistema de Información Geográfica]] (SIG), creado por la empresa [[Keyhole]] Inc., que permite visualizar imágenes en 3D del planeta, combinando imágenes de satélite, mapas y el motor de búsqueda de [[Google]] que permite ver imágenes a escala de un lugar específico del planeta.
'''Google Earth''' is a [[virtual globe]], [[map]] and [[geographic]] information program that was originally called EarthViewer 3D, and was created by [[Keyhole, Inc]], a company acquired by [[Google]] in 2004. It maps the Earth by the [[superimposition]] of images obtained from [[satellite imagery]], [[aerial photography]] and [[geographic information system|GIS]] [[computer graphics|3D]] globe. It is available under three different licenses: Google Earth, a free version with limited functionality; Google Earth Plus (discontinued)<ref>{{cite web |url=http://www.gearthblog.com/blog/archives/2008/12/google_earth_plus_discontinued.html|title=Google Earth Plus Discontinued}}</ref><ref>{{cite web |url=http://www.techpluto.com/google-earth-live/|title=Google Discontinues "Google Earth Plus"}}</ref>, which included additional features; and Google Earth Pro ($400 per year), which is intended for commercial use.<ref name="Google Earth Product Family">{{cite web |url=http://earth.google.com/products.html| title= Google Earth Product Family| accessdate = 2007-08-05}}</ref>


== Desarrollo ==
The product, re-released as Google Earth in 2005, is currently available for use on [[personal computer]]s running [[Windows 2000]] and above, [[Mac OS X]] 10.3.9 and above, [[Linux Kernel]]: 2.4 or later (released on June 12, 2006), and [[FreeBSD]]. Google Earth is also available as a [[browser]] [[plugin]] which was released on May 28, 2008<ref>{{cite web |url=http://google-latlong.blogspot.com/2008/05/google-earth-meet-browser.html|title=Google Earth, meet the browser}}</ref>. It was also made available on the [[iPhone OS]] on October 27, 2008, as a free download from the [[App Store]]. In addition to releasing an updated Keyhole based client, Google also added the imagery from the Earth database to their web based mapping software. The release of Google Earth in June 2005 to the public caused a more than tenfold increase in media coverage on [[virtual globes]] between 2005 and 2006,<ref name="Media Coverage of Geospatial Platforms">{{cite web |url=http://www.geospatialweb.com/figure-4| title=Media Coverage of Geospatial Platforms| accessdate = 2007-08-05}}</ref> driving public interest in [[geospatial]] technologies and applications.


[[Keyhole]] era en un principio un programa de pago hasta que el [[27 de octubre]] de [[2004]] fue comprado por Google. El [[21 de mayo]] de [[2005]] Keyhole pasó a llamarse Google Earth. Este programa fue lanzado (relanzado si se tiene en cuenta que ya existía como Keyhole) el día [[28 de junio]] de 2005 teniendo como principal novedad, aparte del cambio de nombre y de dueño, que el programa disponía de una versión gratuita (a diferencia de Keyhole que era de pago en todas sus versiones, aunque era posible contar con una versión de prueba por tiempo limitado).
==Overview==
En este programa también se incorpora Google Maps, ya que el Google Earth le sirve para encontrar las calles, avenidas y negocios y ampliarlas de una manera muy legibles.

== Google Sky - Modo cielo ==
Google Earth displays satellite images of varying resolution of the Earth's surface, allowing users to see things like cities and houses looking perpendicularly down or at an [[oblique]] angle, with [[Perspective (graphical)|perspective]] (see also [[bird's eye view]]). The degree of resolution available is based somewhat on the points of interest and popularity, but most land (except for some islands) is covered in at least 15 meters of resolution.<ref>[http://earth.google.com/data.html Google Earth Coverage]: Maps showing a visual representation of Google Earth coverage</ref> [[Melbourne|Melbourne, Victoria]], Australia; [[Las Vegas, Nevada]]; and [[Cambridge|Cambridge, Cambridgeshire]] include examples of the highest resolution, at 15&nbsp;cm (6&nbsp;inches). Google Earth allows users to search for addresses for some countries, enter coordinates, or simply use the mouse to browse to a location.

}}</ref>se lanzó la versión 4.2 de Google Earth, que incorpora una herramienta para explorar el cielo, ver estrellas, galaxias y las imágenes astronómicas. [[Google Sky]] es un producto de [[Google]] fruto de un acuerdo con el Instituto de Ciencia Telescópica Espacial de Baltimore, el centro de operaciones del [[Hubble]]. La nueva versión aporta imágenes publicadas en 2007, tomadas por las cámaras del Hubble. El "Modo del Cielo" permite visualizar las constelaciones, estrellas, [[galaxias]] y animaciones que presentan los [[planetas]] y que trazan sus órbitas.


Este programa tiene incorporada una sección de tutoría para guiarse y aprender más de aquellas constelaciones, galaxias, estrellas y planetas más notables.
For large parts of the surface of the Earth only 2D images are available, from almost vertical photography. Viewing this from an oblique angle, there is perspective in the sense that objects which are horizontally far away are seen smaller, but of course it is like viewing a large photograph, not quite like a 3D view.


También permite ver los transbordadores lanzados por la [[NASA]] y la estación espacial.
For other parts of the surface of the Earth 3D images of terrain and buildings are available. Google Earth uses [[digital elevation model]] (DEM) data collected by [[NASA]]'s [[Shuttle Radar Topography Mission]] (SRTM).<ref>Farr et al., 2007, The Shuttle Radar Topography Mission, v. 45, Reviews of Geophysics, doi: 1029/2005RG000183. [http://www2.jpl.nasa.gov/srtm/ SRTM web site]</ref> This means one can view the [[Grand Canyon]] or [[Mount Everest]] in three [[dimension]]s, instead of 2D like other areas. Since November 2006, the 3D views of many mountains, including Mount Everest, have been improved by the use of supplementary DEM data to fill the gaps in SRTM coverage.<ref>{{cite web|url=http://bbs.keyhole.com/ubb/showthreaded.php/Cat/0/Number/695033/an/latest/page/0#695033|title=Google Earth Community: Nov. 23rd - Thanksgiving Day imagery update}}</ref>


== Google Street View ==
Many people use the applications to add their own data, making them available through various sources, such as the [[Bulletin Board Systems]] (BBS) or [[blogs]] mentioned in the link section below. Google Earth is able to show all kinds of images overlaid on the surface of the earth and is also a [[Web Map Service]] client. Google Earth supports managing three-dimensional [[Geospatial]] data through [[Keyhole Markup Language]] (KML).
{{Ap|Google Street View}}
En este apartado, habilitado en capas en la versión 4.3, y hasta la versión 5, se pueden observar fotos esféricas a pie de calle de varias [[ciudad]]es del mundo. La experiencia partió con ciudades estadounidenses y se fue expandiendo a diversas ciudades europeas y latinoamericanas.


== Marte y Luna ==
Google Earth has the capability to show 3D buildings and structures (such as bridges), which consist of users' submissions using [[SketchUp]], a [[3D modeling]] program. In prior versions of Google Earth (before Version 4), 3D buildings were limited to a few cities, and had poorer rendering with no textures. Many buildings and structures from around the world now have detailed 3D structures; including (but not limited to) those in the United States, Canada, Ireland, India, Japan, United Kingdom,<ref>[http://www.skyscrapernews.com/googleearth.php Skyscraper News Google Earth<!-- Bot generated title -->]</ref> Germany, [[Pakistan]] and the cities, [[Amsterdam]] and [[Alexandria]].<ref>[http://www.infopot.tk/ infopot.tk<!-- Bot generated title -->]</ref> In August 2007, [[Hamburg]] became the first city entirely shown in 3D, including textures such as façades. The Irish town of [[Westport, County Mayo|Westport]] was added to Google Earth in 3D on January 16, 2008. The 'Westport3D' model was created by 3D imaging firm AM3TD using long-distance laser scanning technology and digital photography and is the first such model of an Irish town to be created. As it was developed initially to aid Local Government in carrying out their [[town planning]] functions it includes the highest resolution photo-realistic textures to be found anywhere in Google Earth. Three-dimensional renderings are available for certain buildings and structures around the world via Google's 3D Warehouse<ref>[http://sketchup.google.com/3dwarehouse/ 3D Warehouse<!-- Bot generated title -->]</ref> and other websites.


Las últimas versiones (5.0) de Google Earth permiten al usuario ver imágenes en 3D de la [[Luna]] y del planeta [[Marte (planeta)|Marte]], además de ofrecer contenidos interactivos, visitas guiadas y la posibilidad de ver imágenes en una resolución muy elevada, así como poder ver modelos en 3D de los satélites, módulos o sondas que se encuentran en la superficie de dichos astros. Al estar los modelos en 3D, es posible ver cráteres, cordilleras montañosas, cañones o volcanes desde todos los ángulos de manera más o menos fiel a la realidad.
Recently, Google added a feature that allows users to monitor traffic speeds at loops located every 200 yards in real-time. In version 4.3 released on April 15, 2008, [[Google Street View]] was fully integrated into the program allowing the program to provide an on the street level view in many locations.


* '''En Marte''': se tiene la posibilidad de seguir los recorridos de los vehículos, o la capacidad de participar en un tour interactivo por todo el planeta, viendo puntos de interés, como el [[Monte Olimpo (Marte)]]. También es posible ver imágenes de la [[NASA]] unas horas después de que éstas se hayan descargado.
On January 17, 2009, the entirety of Google Earth's ocean floor imagery was updated to new images by SIO, NOAA, US Navy, NGA, and GEBCO. The new images have caused smaller islands, such as some atolls in the [[Maldives]], to be rendered invisible despite their shores being completely outlined.<ref>http://www.gearthblog.com/blog/archives/2009/01/new_view_of_ocean_floor_in_google_e.html</ref>


* '''En la Luna''': es posible ver los lugares donde ocurrieron las misiones del [[Programa Apollo]], con modelos en 3D de las naves de las misiones, y fotos en las que es posible distinguir las huellas de los astronautas. También es posible ver imágenes o vídeos inéditos de cuando las misiones Apollo aterrizaron.

==Uses==
== Versiones ==
El programa Google Earth está disponible en varias versiones:
{{Expand section|date=January 2010}}
In addition to obvious uses, Google Earth is useful for many day-to-day and other purposes.
*Before climbing onto the roof of a building or other relatively inaccessible high place, it can be checked visually with good enough resolution to make out most features.


* Según el nivel de prestaciones: estas se dividen en dos versiones de pago y una versión gratuita.
...
*Google Earth can be used to view areas subjected to widespread disasters if Google supplies up-to-date images. For example after the 12 January [[2010 Haiti earthquake]] images of Haiti were made available on 17 January.


* Según el sistema operativo: Google provee versiones para [[Windows]] (XP y 2000) y, la novedad de [[2006]], es la versión para sistema operativo [[Mac]] OS. El 12 de junio de 2006, Google lanzó la primera versión (Beta 4) de Google Earth para [[Linux]].

* La versión de Google, 4.x, tiene un componente que permite que se visualice en cualquier sistema operativo, se denomina QT4, producto de una empresa holandesa. Por lo tanto la usabilidad en cuanto a los sistemas operativos es muy extensa. La última versión de Google Earth es la 5.x.
==Features==
=== Wikipedia and Panoramio integration===
In December 2006, Google Earth added a new layer called "Geographic Web" that includes integration with [[Wikipedia]] and [[Panoramio]]. In Wikipedia, entries are scraped for coordinates via the {{srlink|Template:Coord|Coord templates}}. There is also a community-layer from the project [[:de:Wikipedia:WikiProjekt Georeferenzierung/Wikipedia-World/en|Wikipedia-World]]. More coordinates are used, different types are in the display and different languages are supported than the built-in Wikipedia layer. See: *[http://tools.wikimedia.de/~kolossos/world-link.php?lang=en dynamic] resp. [http://www.webkuehn.de/hobbys/wikipedia/geokoordinaten/index.htm static] layer. Google announced on May 30, 2007 that it is acquiring [[Panoramio]].<ref>{{cite web|url=http://www.google.com/intl/en/press/annc/annc_panoramio.html|title=Google is planning to acquire Panoramio|publisher=google.com}}</ref> In March 2010, Google removed the "Geographic Web" layer. The "Panoramio" layer became part of the main layers and the "Wikipedia" layer was placed in the "More" layer.


== Características ==
===Flight simulator===
Google Earth permite introducir el nombre de un hotel, colegio o [[calle]] y obtener la dirección exacta, un plano o vista del lugar. También se pueden visualizar imágenes vía [[Satélite artificial|satélite]] del [[Tierra|planeta]]. También ofrece características [[3D]] como dar [[volumen]] a [[valle]]s y [[montaña]]s, y en algunas [[ciudad]]es incluso se han modelado los edificios. La forma de moverse en la pantalla es fácil e intuitiva, con cuadros de mando sencillos y manejables.
[[Image:Toronto downtown.png|400px|right|thumb|Downtown [[Toronto]], as seen from a F16 Fighting Falcon during a simulated flight.]]
Since Google Earth v4.2, a flight simulator has been included as a [[Easter egg (virtual)#Software-based|hidden feature]] (on version 4.3 and above it is not a ''hidden'' feature any more and can be accessed from the Tools menu). Depending on the system, it can be accessed by pressing Control+Alt+A, Control+A, or [[Command key|Command]]+Option+A. After this feature has been activated at least once it appears under the tools menu. Since v4.3 the option is no longer hidden by default. Currently the [[F-16 Fighting Falcon]] and the [[Cirrus SR-22]] are the only aircraft that can be used, in addition to a few airports.<ref>[http://marco-za.blogspot.com/2007/08/google-earth-flight-simulator.html Marco's Blog: Google Earth Flight Simulator<!-- Bot generated title -->]</ref> It is also possible to control the simulator with a mouse or joystick, although not all models are currently supported.


Además, es posible compartir con otros usuarios enlaces, medir distancias geográficas, ver la altura de las montañas, ver [[falla]]s o [[volcán|volcanes]] y cambiar la vista tanto en [[horizontal]] como en [[vertical]].
====Featured planes====
* [[F-16 Fighting Falcon]]&nbsp;– A much higher speed and maximum altitude than the Cirrus SR-22, it has the ability to fly at speeds of almost 1,300 knots near ground level.{{Citation needed|date=March 2009}}, and up to 1703 knots under water in free fall.


Google Earth también dispone de conexión con [[GPS]] (Sistema de Posicionamiento Global), alimentación de datos desde fichero y base de datos en sus versiones de pago.
* [[Cirrus SR-22]]&nbsp;– Although slower and with a lower maximum altitude, the SR-22 is much easier to handle and is preferred for up-close viewing of Google Earth's imagery.


También tiene un [[simulador de vuelo]] de Google Earth bastante real con el que se puede sobrevolar cualquier lugar del planeta.
===Sky mode===

La versión 4 ha incorporado notables mejoras:
'''[[Google Sky]]''' is a feature that was introduced in Google Earth 4.2 on August 22, 2007, and allows users to view [[star]]s and other [[celestial bodies]].<ref>{{cite web | title =Explore the sky with Google Earth | publisher =Google | date= 2007-08-22 | url =http://earth.google.com/sky/skyedu.html | accessdate =2007-08-22 }}</ref> It was produced by [[Google]] through a partnership with the [[Space Telescope Science Institute]] (STScI) in Baltimore, the science operations center for the [[Hubble Space Telescope]]. Dr. [[Alberto Conti]] and his co-developer Dr. [[Carol Christian]] of STScI plan to add the public images from 2007,<ref>[http://technology.newscientist.com/article/dn12523 Celestial add-on points Google Earth at the stars - tech - August 22, 2007 - New Scientist Tech<!-- Bot generated title -->]</ref> as well as color images of all of the archived data from Hubble's Advanced Camera for Surveys. Newly released [[Hubble]] pictures will be added to the Google Sky program as soon as they are issued. New features such as multi-wavelength data, positions of major satellites and their orbits as well as educational resources will be provided to the Google Earth community and also through Christian and Conti's [http://hubblesite.org/explore_astronomy/gsky/ website for Sky]. Also visible on Sky mode are constellations, stars, galaxies and animations depicting the planets in their orbits. A real-time Google Sky [[Mashup (web application hybrid)|mashup]] of recent astronomical transients, using the [[VOEvent]] protocol, is being provided by the [http://voeventnet.org/ VOEventNet] collaboration. Google's Earth maps are being updated each 5 minutes.

|- style="background:#dbe5f1;"

|style="text-align: justify;"|Precio USD||Gratis||20||400/año||
Google Street View provides 360° panoramic street-level views and allows users to view parts of selected cities and their surrounding metropolitan areas at ground level. When it was launched on May 25, 2007 for [[Google Maps]], only five cities were included. It has since expanded to more than 40 U.S. cities, and includes the suburbs of many, and in some cases, other nearby cities. Recent updates have now implemented Street View in most of the major cities of Australia and New Zealand as well as parts of Canada, Mexico, Japan, Spain, France, the UK, the Netherlands, Italy, Switzerland, Portugal, Taiwan and Singapore.

Google Earth 5 includes a separate globe of the planet Mars, that can be viewed and analysed for research purposes. The maps are of a much higher resolution than those on the browser version of [[Google Mars]] and it also includes 3D renderings of the Martian terrain. There are also some extremely high resolution images from the [[Mars Reconnaissance Orbiter]]'s [[HiRISE]] camera that are of a similar resolution to those of the cities on Earth. Finally, there are many high resolution panoramic images from various Mars landers, such as the [[Mars Exploration Rovers]], [[Spirit Rover|Spirit]] and [[Opportunity Rover|Opportunity]], that can be viewed in a similar way to [[Google Street View]]. Interestingly enough, layers on Google Earth (such as World Population Density) can also be applied to Mars. Layers of Mars can also be applied onto Earth. Mars also has a small application found near the face on Mars. It is called Meliza, and features a chat between you and an automatic robot speaker. It is useful for research on Mars, but is not recommended for normal conversations.

On July 20, 2009, the 40th anniversary of the [[Apollo 11]] mission, Google introduced the Google Earth version of [[Google Moon]],<ref>http://www.gearthblog.com/blog/archives/2009/07/look_at_the_moon_in_google_earth_-.html</ref> which allows users to view satellite images of the [[Moon]]. It was announced and demonstrated to a group of invited guests by Google along with [[Buzz Aldrin]] at the [[Newseum]] in [[Washington, D.C.]].<ref>http://www.gearthblog.com/blog/archives/2009/07/google_earth_event_on_july_20th_in.html</ref><ref>http://google-latlong.blogspot.com/2009/07/fly-yourself-to-moon.html</ref>

Google Earth can be traced directly back to a small company named [[Autometric]], now a part of [[Boeing]]. Autometric created a visualization product named Edge Whole Earth and demonstrated this to Michael T. Jones. Chris Tanner, and others at SGI in 1996. Several other visualization products using imagery existed at the time, including Performer-based ones, but Michael T. Jones stated emphatically that he had "never thought of the complexities of rendering an entire globe..." The catch phrase "from outer space to in your face" was coined by Autometric President Dan Gordon, and used to explain his concept for personnel/local/global range. Edge blazed a trail as well in broadcasting, being used in 1997 on [[CBS News]] with [[Dan Rather]], in print for rendering large images draped over terrain for National Geographic, and used for special effects in the feature film Shadow Conspiracy in 1997. In 2000, Edge Viewer was made available through the [[National Geospatial-Intelligence Agency]] for free.

Mr. Gordon was a huge fan of the ‘Earth’ program described in [[Neal Stephenson]]'s [[sci-fi]] classic ''[[Snow Crash]]''. Indeed, a Google Earth co-founder claimed that Google Earth was modeled after ''Snow Crash'',<ref>[http://www.webuser.co.uk/news/227346.html Web User - Google Earth interview]</ref> while another co-founder said it was inspired by the short science education film ''[[Powers of Ten]]''.<ref name="google_earth1">[http://www.brownianemotion.org/2006/07/24/notes-on-the-origin-of-google-earth/ Avi Bar-Ze’ev (from Keyhole, the precursor to Google Earth) on origin of Google Earth]</ref> In fact Google Earth was at least partly inspired by a [[Silicon Graphics]] demo called "From Outer Space to in Your Face" which zoomed from space into the [[Swiss Alps]] then into the [[Matterhorn]].<ref>[http://bnhsu.wordpress.com/2007/04/30/google-earth-from-space-to-your-face%E2%80%A6and-beyond/ Google Earth: From Space to Your Face…and Beyond]</ref> This launch demo was hosted by an [[SGI Origin 3000 and Onyx 3000|Onyx 3000]] with [[InfiniteReality#InfiniteReality4|InfiniteReality4]]<ref>[http://www.futuretech.blinkenlights.nl/ir_techreport.html Infinite Reality Technical Report<!-- Bot generated title -->]</ref> graphics, which supported [[Clip Mapping]] and was inspired by the hardware texture paging capability (although it did not use the Clip Mapping) and "Powers of Ten". The first Google Earth implementation called Earth Viewer emerged from [[Intrinsic Graphics]] as a demonstration of Chris Tanner's software based implementation of a [[Clip Mapping]] texture paging system and was spun off as Keyhole Inc. Earth Viewer was the inevitable ultimate realization of the capabilities of a seamless texture paging system and many of the individuals working on Earth Viewer were Silicon Graphics alumni.

===Imagery and coordination===
<!-- Commented out because image was deleted: [[Image:Google earth default interface earth and stars.png|300px|thumb|Google Earth comes with atmosphere effects and seabed]] -->
* Coordinate System and Projection
** The internal coordinate system of Google Earth is geographic coordinates (latitude/longitude) on the [[WGS84|World Geodetic System]] of 1984 (WGS84) datum.
** Google Earth shows the earth as it looks from an elevated platform such as an airplane or orbiting satellite. The projection used to achieve this effect is called the [[General Perspective Projection|General Perspective]]. This is similar to the [[Orthographic projection (cartography)|Orthographic projection]], except that the point of perspective is a finite (near earth) distance rather than an infinite (deep space) distance.
* Baseline resolutions
** Czech Republic: 0.1 - 0.5 m (by Eurosense / Geodis Brno)
** Slovakia: 0.5 m (by Eurosense / Geodis Slovakia)
** Hungary: 2.5 m SPOT Images. Budapest approx. 0,3 m.
** Germany, Switzerland, Netherlands, Denmark, U.K., Andorra, Luxembourg, Liechtenstein, San Marino, Vatican City: 1 m or better
** Balkans: 2.5 m (medium resolution)
** U.S.: 1 m (excludes Alaska & Hawaii)
** Global: Generally 15 m (some areas, such as [[Antarctica]], are in extremely low resolution), but this depends on the quality of the satellite/aerial photograph uploaded.
* Typical high resolutions
** Europe: 0.3 m, 0.15 m (e.g. Berlin, [[Zürich]], [[Hamburg]]), 0.1 m [[Prague]]
** U.S.: 1 m, 0.6 m, 0.3 m, 0.15 m (extremely rare; e.g. [[Cambridge, Massachusetts|Cambridge]] and Google Campus, or [[Glendale, California|Glendale]])
* Altitude resolution:
** Surface: varies by country
** Seabed: Not previously applicable, but since the introduction of "Ocean", elevation data has been introduced (a colorscale approximating sea floor depth is "printed" on the spherical surface at views from high altitudes).
* Age: Images dates vary. The image data can be seen from squares made when DigitalGlobe Coverage is enabled. The date next to the copyright information is not the correct image date. Zooming in or out could change the date of the pictures. Most of the international urban image dates are from 2004 and have not been updated. However, most US images are kept current. Google announces imagery updates on their LatLong Blog<ref>[http://earth.google.com/sky/skyedu.html Google Earth<!-- Bot generated title -->]</ref> in form of a quiz, with hints of the updated locations. The answers are posted some days later in the same blog.

===Hardware and software===
Google Earth is unlikely to operate on older hardware configurations. The [http://earth.google.com/support/bin/answer.py?hl=en&answer=20701 most recent system requirements update] document these minimum configurations:
* [[Pentium 3]], 500[[MHz]]
* 256 [[Megabyte]]s of [[Random Access Memory|RAM]]
* 400 MB free [[hard drive|disk]] space
* Network speed: 128 kbit/s
* 16MB 3D-capable [[graphics card]]
* Resolution of 1024x768, 16-bit High Color
* [[Windows XP]], [[Windows 2000]], [[Windows Vista]], [[Windows 7]], [[Linux]] or [[Mac OS X]]

The most likely mode of failure is insufficient video RAM: the software is designed to warn the user if their graphics card is not able to support Earth (this often occurs due to insufficient [[Video RAM]] or buggy graphics card drivers). The next most likely mode of failure is Internet access speed. Except for the very patient, [[broadband Internet]] (Cable, DSL, T1, etc.) is required.

==Versions and variations==
* En febrero de 2009, el periódico [[Telegraph]], del Reino Unido, publicó un artículo insinuando que usando Google Ocean se podía ver un misterioso rectángulo cerca de las Islas Canarias, bajo el mar en las coordenadas 35°15′15″N 24°15′30.53″O / 35.25417, -24.2584806. Inmediatamente, expertos y fanáticos de la Atlántida comenzaron a especular, asegurando que la imagen correspondía a la ciudad hundida. Google afirmó que la imagen corresponde a un típico error de procesamiento de imagen al momento que se recolectaron los datos de Batimetría de varios sonares de botes en la zona".{{Añadir referencias}}

===Mac version===
== Referencias ==
{{listaref}}
A version for [[Mac OS X]] was released on January 10, 2006, and is available for download from the Google Earth website. With a few exceptions noted below, the Mac version appears to be stable and complete, with virtually all the same functionality as the original Windows version.


== Enlaces externos ==
Screenshots and an actual binary of the Mac version had been leaked to the Internet on December 8, 2005. The leaked version was significantly incomplete. Among other things, neither the Help menu nor its "Display License" feature worked, indicating that this version was intended for Google's internal use only. Google released no statement regarding the leak.

The Mac version runs only under Mac OS X version [[Mac OS X v10.4|10.4]] or later. There is no embedded browser, no direct interface to [[Gmail]] and no full screen option. As of January 2009 there are a few bugs concerning the menu bar when switching between applications and a few bugs concerning annotation balloons and printing.
[[Categoría:Geomática]]

[[Categoría:Freeware]]
From version 4.1.7076.4558 (released on May 9, 2007) onward Mac OS X users can, among other new features, upgrade to the "Plus" version via an option in the Google Earth menu.<ref>{{cite web|url=http://www.macupdate.com/info.php/id/20124|title=Google Earth 4.2.180.1134 - MacUpdate}}</ref> Some users reported difficulties with Google Earth crashing in the then current version when zooming in.<ref>{{cite web|url=http://bbs.keyhole.com/ubb/postlist.php/Cat/0/Board/SupportGEMac|title=Google Earth Community: Viewing forum: Google Earth for Mac OS X}}</ref>
[[Categoría:Software de 2005]]

===Linux version===
Starting with the version 4 beta Google Earth functions under [[Linux]], as a native port using the [[Qt (toolkit)|Qt-toolkit]]. It is [[proprietary software]] specifically in order to impose [[Digital Rights Management]]{{Citation needed|date=July 2009}}; the [[Free Software Foundation]] consider the development of a free compatible client for Google Earth to be a [[Free Software Foundation#High priority projects|High Priority Free Software Project]].<ref>[http://www.fsf.org/campaigns/priority.html]:FSF:High Priority Free Software Projects</ref>

===iPhone OS version===
A version for the [[iPhone OS]], which runs both the [[iPhone]] and [[iPod Touch]], was released for free on the [[App Store]] on October 27, 2008.<ref>{{cite web| url=http://blog.wired.com/gadgets/2008/10/google-earth-co.html| title=Google Earth Comes to the iPhone|publisher=''[[Wired (magazine)|Wired]]''| date=2008-10-27|last=Sorrel|first=Charlie| accessdate=2008-10-27}}</ref><ref>{{cite web| url=http://googlemobile.blogspot.com/2008/10/google-earth-now-available-for-iphone.html| title=Google Earth now available for the iPhone|publisher=Google Mobile team| date=2008-10-27| accessdate=2008-10-27}}</ref> It makes use of the [[multi-touch]] interface to move on the globe, zoom or rotate the view, and allow to select the current location using the iPhone integrated [[Assisted GPS]]. This version, however, does not feature layers like computer versions do. Like Google Maps, it only integrates the Wikipedia and Panoramio layers.<ref>http://www.gearthblog.com/blog/archives/2008/10/google_earth_for_the_iphone_release.html</ref>

===Google Earth Plus===
Discontinued in December 2008, Google Earth Plus was an individual-oriented paid subscription upgrade to Google Earth that provided customers with the following features, most of which are now available in the free Google Earth:
* [[GPS]] integration: read tracks and waypoints from a [[Global Positioning System|GPS]] device. A variety of third party applications have been created which provide this functionality using the basic version of Google Earth by generating KML or KMZ files based on user-specified or user-recorded waypoints. However, Google Earth Plus provides direct support for the [[Thales Navigation|Magellan]] and [[Garmin]] product lines, which together hold a large share of the GPS market.<br> The Linux version of the Google Earth Plus application does not include any GPS functionality.
* Higher resolution printing.
* Customer support via email.
* Data importer: read address points from [[Comma-separated values|CSV]] files; limited to 100 points/addresses. A feature allowing path and polygon annotations, which can be exported to [[Keyhole Markup Language|KML]], was formerly only available to Plus users, but was made free in version 4.0.2416.
* Higher data download speeds

===Google Earth Pro===
For a $400 annual subscription fee, Google Earth Pro is a business-oriented upgrade to Google Earth that has more features than the Plus version. The Pro version includes add-on software such as:
* Movie making.
* GIS data importer.
* Advanced printing modules.
Originally, these features cost extra in addition to the $400 fee, but more recently have been included in the package.

Unlike the free version of Google Earth, the professional version does not work on Linux.

===Google Earth Enterprise===
Google Earth Enterprise is a version of Google Earth designed for use by organizations whose business could take advantage of the program's capabilities.<ref>http://earth.google.com/enterprise/earth_enterprise.html</ref>

===Portable version===
{{Expand section|date=March 2009}}
A [http://hacktolive.org/wiki/Portable_Applications_(Windows) portable version of Google Earth], made with [[VMware ThinApp]] is available.<ref>[http://hacktolive.org/wiki/Portable_Applications_(Windows) Portable Applications (Windows)]</ref>. A [http://hacktolive.org/wiki/Portable_Applications_(Linux) Portable version for Linux] is also available, using the [[RUNZ]] format.

An automotive version will be available in 2010 in the new [[Audi A8]].<ref>http://google-latlong.blogspot.com/2009/12/google-audi-take-google-services-in-car.html</ref>

==Google Earth Plug-in==
The Google Earth API is a free beta service, available for any web site that is free to consumers. The Plug-in and its JavaScript API allows users to place a version of Google Earth into web pages. The API does not have all the features of the full Google Earth Application but enables sophisticated 3D map applications to be built.

The Google Earth Plug-in is currently available for the following web browsers and operating systems:

Microsoft Windows (2000, XP, Vista, and 7)
* Google Chrome 1.0+
* Internet Explorer 6.0+
* Firefox 2.0+
* Flock 1.0+

Apple Mac OS X 10.4 and higher (Intel and PowerPC)
* Safari 3.1+
* Firefox 3.0+

To date the plug-in supports the following layers:
* Terrain
* Roads
* Buildings
* Borders
* 3-D Buildings

It also supports 'Sky Mode', 'Photo Overlays', and provides much of the same controls and information bar as the full application.

==Resolution and accuracy==
{{Unreferenced section|date=May 2009}}
[[Image:Google Scilly.jpg|thumb|The [[Isles of Scilly]], showing the very low resolution of some islands. The islands (green area) are about 10 km across. (This is now improved.){{Coord|49|56|10.81|N|6|19|22.88|W|region:GB_type:isle|name=Low resolution Isles of Scilly}}]]

[[Image:GoogleGib.jpg|thumb|left|The west side of [[Gibraltar]] ([[UK]]), tilted view showing the sea rising up the [[Rock of Gibraltar]] - claimed altitude of the sea just off the beach at Elliots Memorial, 252 m. This is now fixed. {{Coord|36|6|59.6|N|5|21|5.2|W|name=Water altitude problem in Google Earth}}]]
Most land areas are covered in satellite imagery with a resolution of about 15 m per pixel. This base imagery is 30m [[multispectral]] [[Landsat]] which is [[Pansharpened image|pansharpened]] with the 15m [panchromatic] [[Landsat]] imagery. However, Google is actively replacing this base imagery with 2.5m [[Spot Image|SPOTImage]] imagery and several higher resolution datasets mentioned below. Some population centers are also covered by aircraft imagery ([[orthophoto]]graphy) with several pixels per meter. Oceans are covered at a much lower resolution, as are a number of islands; notably, the [[Isles of Scilly]] off southwest England, were at a resolution of about 500 m or less, however this has now been addressed.

Google has resolved many inaccuracies in the vector mapping since the original public release of the software, without requiring an update to the program itself. An example of this was the absence from Google Earth's map boundaries of the [[Nunavut]] territory in Canada, a territory that had been created on April 1, 1999; this mistake was corrected by one of the data updates in early 2006. Recent updates have also increased the coverage of detailed aerial photography, particularly in certain areas of western and central Europe.

The images are not all taken at the same time, but are generally current to within three years. However with the release of Google Earth 5.0, it has historical images dating back to the 1940s in some spots. Image sets are sometimes not correctly stitched together. Updates to the photographic database can occasionally be noticed when drastic changes take place in the appearance of the landscape, for example Google Earth's incomplete updates of [[New Orleans]] following [[Hurricane Katrina]], or when placemarks appear to shift unexpectedly across the Earth's surface. Though the placemarks have not in fact moved, the imagery is composed and stitched differently. Such an update to London's photography in early 2006 created shifts of 15–20 metres in many areas, noticeable because the resolution is so high.

Place name and road detail vary greatly from place to place. They are most accurate in North America, Europe and Australia, but regular mapping updates are improving coverage elsewhere.

Errors sometimes occur due to the technology used to measure the height of terrain; for example, tall buildings in [[Adelaide]], Australia cause one part of the city to be rendered as a small mountain, when it is in fact flat. Also, in [[Downtown Los Angeles]], there is a large hill in the approximate location of [[Bunker Hill]], where many of the skyscrapers are located. The height of the [[Eiffel Tower]] creates a similar effect in the rendering of Paris. Also, prior to the release of version 5.0 in February 2009, elevations below sea level were presented as sea level, for example: [[Salton City, California]]; [[Badwater|Death Valley]]; and the [[Dead Sea]] were all listed as 0 m when Salton City is −38 m; Death Valley is −86 m; and the Dead Sea is −420 m.

Where no 3 [[minute of arc|arc second]] [[digital elevation model|digital elevation data]] was available, the three dimensional images covering some areas of high relief are not at all accurate, but most mountain areas are now well mapped. The underlying digital elevation model has been placed 3 [[minute of arc|arc seconds]] too far north and up to 3 arc seconds too far west. This means that some steep mountain ridges incorrectly appear to have shadows extending over onto their south facing sides. Some high resolution images have also been misplaced, an example is the image covering [[Annapurna]], which is misplaced by about 12 arc seconds. Elevation data was recently updated to 10-meter (1/3-arc-second) resolution for much of the United States from the previous 30-meter (1-arc-second) resolution.

In some areas, local government jurisdictions have submitted more finely gridded terrain models through the Map Content Partners program <ref name="MapContentPartners">{{cite web |url=http://www.google.com/submityourcontent/public_sector.html| title=Google Map Content Partners, Public Sector/Non-profit | accessdate=2010-04-11}}</ref>. In March 2010, the County of Marin, just north of the Golden Gate Bridge by San Francisco, California, published a 40 cm gridded terrain surface of 1425 square km through the program.

The "Measure" function shows that the length of [[equator]] is about 40,030.24&nbsp;km, giving an error of −0.112% compared with the actual value of 40,075.02&nbsp;km Earth; for the [[meridian (geography)|meridional]] circumference, it shows a length of about 39,963.13&nbsp;km, also giving an error of −0.112% compared with the actual value of 40,007.86&nbsp;km.

On December 16, 2007, most of Antarctica was updated to a 15 m resolution using imagery from the Landsat Image Mosaic of Antarctica; (1m resolution images of some parts of Antarctica were added in June 2007); however, the Arctic [[polar ice cap]] is completely absent from the current version of Google Earth, as are waves in the oceans. The geographic [[North Pole]] is found hovering over the Arctic Ocean and the tiling system produces [[virtual artifact|artifacts]] near the poles as the tiles become 'infinitely' small and rounding errors accumulate.

Cloud cover and shadows can make it difficult or impossible to see details in some land areas, including the shadow side of mountains.

==Controversy/Criticism==
The software has been criticized by a number of special interest groups, including national officials, as being an invasion of privacy and even posing a threat to national security. The typical argument is that the software provides information about military or other critical installations that could be used by [[terrorist]]s. The following is a selection of such concerns:
* Former Indian president [[APJ Abdul Kalam]] expressed concern over the availability of high-resolution pictures of sensitive locations in India.<ref name="IndianPresCrit">{{cite web |url=http://www.techtree.com/techtree/jsp/article.jsp?article_id=68712&cat_id=582| title=Kalam Concerned Over Google Earth | accessdate=2007-01-25}}</ref> Google subsequently agreed to censor such sites.<ref>{{cite web|url=http://timesofindia.indiatimes.com/Google_Earth_agrees_to_blur_pix_of_key_Indian_sites/articleshow/1559236.cms|title="Google Earth agrees to blur pix of key Indian sites"}}</ref>
* The [[Indian Space Research Organisation]] said Google Earth poses a security threat to India, and seeks dialogue with Google officials.<ref name="ISROCrit">{{cite web |url=http://www.techshout.com/internet/2006/10/google-earth-poses-security-threat-to-india-isro-chief-seeks-dialogue/| title="Google Earth Poses Security Threat to India, ISRO Chief seeks Dialogue" | accessdate=2007-01-25}}</ref>
* Google marks all the northern Indian borders in red color including those that are not disputed. Northern borders of Himachal Pradesh, Uttarakhand that are never discussed in border disputes with China are marked red.
* The South Korean government expressed concern that the software offers images of the presidential palace and various military installations that could possibly be used by their hostile neighbor [[North Korea]].<ref name="SouthKoreaGovCrit">{{cite web |url=http://www.worldtribune.com/worldtribune/TEMP/ea_skorea_09_06.html| title="Google Earth images compromise secret installations in S.

* In 2006, one user spotted a large topographical replica in a remote region of China.

* In 2009, Google superimposed old [[woodblock prints]] of maps from 18th and 19th century [[Japan]] over Japan today. These seemingly harmless maps marked areas inhabited by the <B>[[burakumin]]</B> caste, who were considered "non-humans" for their "dirty" occupations, including [[leather tanning]] and [[butchery]]. Descendants of burakumin outcastes still face discrimination today and many Japanese people feared that some would use these areas, labeled <b>etamura</b> (穢多村, <i>translation: "village of the filthy masses"</I>), to target current inhabitants of them. These maps are still visible on Google Earth, but with the label removed where necessary.<ref>[http://www.timesonline.co.uk/tol/news/world/asia/article6337499.ece "Google Earth maps out discrimination against burakumin caste in Japan"], The Times Online, May 2009, accessed March 23, 2010.</ref>

Some citizens may express concerns over aerial information depicting their properties and residences being disseminated freely. As relatively few jurisdictions actually guarantee the individual's [[right to privacy]], as opposed to the state's right to secrecy, this is an evolving, but minor, point.
Perhaps aware of these critiques<ref>[http://spatiallaw.blogspot.com/2008/04/privacy-lawsuit-against-google-earth.html Privacy Lawsuit Against Google Earth], Spatial Law blog, 2008-04-09
</ref>, for a time, Google had [[Area 51]] (which is highly visible and easy to find) in Nevada as a default placemark when Google Earth is first installed.

As a result of pressure from the United States government, the residence of the [[Vice President of the United States|Vice President]] at [[Number One Observatory Circle]] was obscured through [[pixelization]] in Google Earth and [[Google Maps]], but has since been lifted. The usefulness of this downgrade is questionable, as high-resolution photos and aerial surveys of the property are readily available on the Internet elsewhere.<ref>{{cite web|url=http://www.eyeball-series.org/veep-eyeball.htm|title=Eyeballing the US Vice Presidential Residence}}</ref> [[Capitol Hill]] used to also be pixelized in this way, but this was lifted.

Critics have expressed concern over the willingness of Google to cripple their dataset to cater to special interests, believing that intentionally obscuring any land goes against its stated goal of letting the user "point and zoom to any place on the planet that you want to explore".<ref>{{cite web|url=http://www.geospace.co.uk/files/Zook_Graham_2007_Geoforum.pdf|title="The Creative Reconstruction of the Internet: Google and the Privatization of Cyberspace and DigiPlace"}}</ref>

Recent versions of Google Earth require a software component running in the background that will automatically download and install updates. Several users expressed concerns that there is not an easy way to disable this updater, as it currently runs without the permission of the user.<ref>{{cite web|url=http://www.wired.com/epicenter/2009/02/why-googles-sof/|title="Why Google's Software Update Tool Is Evil"}}</ref>

==Copyright==
Currently, every image created from Google Earth using satellite data provided by Google Earth is a [[copyright]]ed map. Any derivative from Google Earth is made from copyrighted data which, under [[United States Copyright Law]], may not be used except under the licenses Google provides. Google allows [[non-commercial]] personal use of the images (e.g. on a personal website or blog) as long as copyrights and attributions are preserved.<ref>Google Earth Help Center: [http://earth.google.com/support/bin/answer.py?answer=21422 Can I post images to the web?]</ref>
By contrast, images created with NASA's globe software [[NASA World Wind|World Wind]] use the [[Blue Marble]], [[Landsat]] or USGS layer, each of which is a terrain layer in the [[public domain]]. Works created by an agency of the United States government are public domain at the moment of creation. This means that those images can be freely modified, redistributed and used for [[Commerce|commercial]] purposes.

==Layers==
Google Earth also features many layers as a source for information on businesses and points of interest, as well as showcasing the contents of many communities, such as [[Wikipedia]], [[Panoramio]] and [[YouTube]]. Google updates with new layers often. Many Google Earth layers, such as Panoramio and Google Earth Community layers, are updated daily with entries from the respective websites.

===Borders and labels===
Contains borders for countries/provinces and shows placemarks for cities and towns.
* [[Border]]s: ''Marks international borders with a thick yellow line, 1st level administrative borders (generally [[province]]s and [[State (administrative division)|states]]) with a [[lavender (color)|lavender]] line, and 2nd level administrative borders ([[county|counties]]) with a [[cyan]] line. Coastlines appear as a thin yellow line. Displays names of [[country|countries]], 1st level administrative areas, and islands.''
* Labels: ''Displays labels for large bodies of water, such as oceans, seas, and bays, and populated places.''

===Places of interest===
A collection of business listings provided by many local services.

===Panoramio===
Shows many of the most relevant pictures uploaded onto Panoramio's website

===Roads===
Displays available road networks. The colors and signs displayed vary depending on the type of roadway.
* [[limited-access road|Limited-access]] [[freeway]]s and [[tollway]]s that are part of widespread networks such as the [[International E-road network]], United States [[Interstate Highway System|Interstate Highways]] and many other national road networks are represented by orange lines.
* Other freeways are marked with pale orange lines.
* Some roads in Japan are indigo.
* Other important roads, generally those most travelled, highest capacity, or bearing a [[road number]], are labeled with yellow lines.
* All other roads are labeled white.
* Some [[pedestrian]] walkways and [[private road]]s are signified by [[transparent]] white lines, especially when greatly resembling a road intended for public automotive traffic.

===3D Buildings===
Shows many 3D buildings in major cities, such as New York City or [[Hong Kong]], in these styles:
* Photorealistic: ''Shows many buildings in a realistic style, with more complex polygons and surface images.''
* Gray: ''Low-detail models of city buildings designed for computers that may not have the capability of showing the photorealistic models.''

In 2009, in a unique collaboration between Google and the [[Museo del Prado]] in Madrid, the museum selected 14 of its most important paintings to be photographed and displayed at the ultrahigh resolution of 14,000 [[megapixel]]s inside the 3D version of the Prado in Google Earth and [[Google Maps]].<ref>{{citation|url=http://www.guardian.co.uk/artanddesign/2009/jan/14/museums-internet-google-earth-prado|title=Online gallery zooms in on Prado's masterpieces (even the smutty bits)|author=Giles Tremlett|date=14 January 2009|newspaper=The Guardian | location=London}}</ref><ref>{{citeweb|url=http://www.google.com/intl/en/landing/prado/|title=The Prado in Google Earth|accessdate=2010-04-03|publisher=Google}}</ref>

Google Earth es un programa informático similar a un Sistema de Información Geográfica (SIG), creado por la empresa Keyhole Inc., que permite visualizar imágenes en 3D del planeta, combinando imágenes de satélite, mapas y el motor de búsqueda de Google que permite ver imágenes a escala de un lugar específico del planeta.

Desarrollo

Keyhole era en un principio un programa de pago hasta que el 27 de octubre de 2004 fue comprado por Google. El 21 de mayo de 2005 Keyhole pasó a llamarse Google Earth. Este programa fue lanzado (relanzado si se tiene en cuenta que ya existía como Keyhole) el día 28 de junio de 2005 teniendo como principal novedad, aparte del cambio de nombre y de dueño, que el programa disponía de una versión gratuita (a diferencia de Keyhole que era de pago en todas sus versiones, aunque era posible contar con una versión de prueba por tiempo limitado). En este programa también se incorpora Google Maps, ya que el Google Earth le sirve para encontrar las calles, avenidas y negocios y ampliarlas de una manera muy legibles.

Google Sky - Modo cielo

El 22 de agosto de 2007[1]​se lanzó la versión 4.2 de Google Earth, que incorpora una herramienta para explorar el cielo, ver estrellas, galaxias y las imágenes astronómicas. Google Sky es un producto de Google fruto de un acuerdo con el Instituto de Ciencia Telescópica Espacial de Baltimore, el centro de operaciones del Hubble. La nueva versión aporta imágenes publicadas en 2007, tomadas por las cámaras del Hubble. El "Modo del Cielo" permite visualizar las constelaciones, estrellas, galaxias y animaciones que presentan los planetas y que trazan sus órbitas.

Este programa tiene incorporada una sección de tutoría para guiarse y aprender más de aquellas constelaciones, galaxias, estrellas y planetas más notables.

También permite ver los transbordadores lanzados por la NASA y la estación espacial.

Google Street View

Artículo principal: Google Street View

En este apartado, habilitado en capas en la versión 4.3, y hasta la versión 5, se pueden observar fotos esféricas a pie de calle de varias ciudades del mundo. La experiencia partió con ciudades estadounidenses y se fue expandiendo a diversas ciudades europeas y latinoamericanas.

Marte y Luna

Las últimas versiones (5.0) de Google Earth permiten al usuario ver imágenes en 3D de la Luna y del planeta Marte, además de ofrecer contenidos interactivos, visitas guiadas y la posibilidad de ver imágenes en una resolución muy elevada, así como poder ver modelos en 3D de los satélites, módulos o sondas que se encuentran en la superficie de dichos astros. Al estar los modelos en 3D, es posible ver cráteres, cordilleras montañosas, cañones o volcanes desde todos los ángulos de manera más o menos fiel a la realidad.

  • En Marte: se tiene la posibilidad de seguir los recorridos de los vehículos, o la capacidad de participar en un tour interactivo por todo el planeta, viendo puntos de interés, como el Monte Olimpo (Marte). También es posible ver imágenes de la NASA unas horas después de que éstas se hayan descargado.
  • En la Luna: es posible ver los lugares donde ocurrieron las misiones del Programa Apollo, con modelos en 3D de las naves de las misiones, y fotos en las que es posible distinguir las huellas de los astronautas. También es posible ver imágenes o vídeos inéditos de cuando las misiones Apollo aterrizaron.

Versiones

El programa Google Earth está disponible en varias versiones:

  • Según el nivel de prestaciones: estas se dividen en dos versiones de pago y una versión gratuita.
  • Según el sistema operativo: Google provee versiones para Windows (XP y 2000) y, la novedad de 2006, es la versión para sistema operativo Mac OS. El 12 de junio de 2006, Google lanzó la primera versión (Beta 4) de Google Earth para Linux.
  • La versión de Google, 4.x, tiene un componente que permite que se visualice en cualquier sistema operativo, se denomina QT4, producto de una empresa holandesa. Por lo tanto la usabilidad en cuanto a los sistemas operativos es muy extensa. La última versión de Google Earth es la 5.x.

Características

Google Earth permite introducir el nombre de un hotel, colegio o calle y obtener la dirección exacta, un plano o vista del lugar. También se pueden visualizar imágenes vía satélite del planeta. También ofrece características 3D como dar volumen a valles y montañas, y en algunas ciudades incluso se han modelado los edificios. La forma de moverse en la pantalla es fácil e intuitiva, con cuadros de mando sencillos y manejables.

Además, es posible compartir con otros usuarios enlaces, medir distancias geográficas, ver la altura de las montañas, ver fallas o volcanes y cambiar la vista tanto en horizontal como en vertical.

Google Earth también dispone de conexión con GPS (Sistema de Posicionamiento Global), alimentación de datos desde fichero y base de datos en sus versiones de pago.

También tiene un simulador de vuelo de Google Earth bastante real con el que se puede sobrevolar cualquier lugar del planeta.

La versión 4 ha incorporado notables mejoras:

Curiosidades
