This means one can view the Grand Canyon or Mount Everest in three dimensions, instead of 2D like other areas. Google Earth uses digital elevation model (DEM) data collected by NASA's Shuttle Radar Topography Mission (SRTM). 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.įor other parts of the surface of the Earth 3D images of terrain and buildings are available. Google Earth allows users to search for addresses for some countries, enter coordinates, or simply use the mouse to browse to a location.įor large parts of the surface of the Earth only 2D images are available, from almost vertical photography. Melbourne, Victoria Las Vegas, Nevada and Cambridge, Cambridgeshire include examples of the highest resolution, at 15 cm (6 inches). 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. Google Earth displays satellite images of varying resolution of the Earth's surface, allowing users to visually see things like cities and houses looking perpendicularly down or at an oblique angle, with perspective (see also bird's eye view). 2.1 Wikipedia and Panoramio integrationĪ rendering of the Flatirons in Boulder, Colorado by Google Earth.The release of Google Earth in June 2005 to the public caused a more than tenfold increase in media coverage on virtual globes between 20, driving public interest in geospatial technologies and applications. In addition to releasing an updated Keyhole based client, Google also added the imagery from the Earth database to their web-based mapping software. It was also made available on the iPhone OS on October 27 2008, as a free download from the App Store. Google Earth is also available as a browser plug-in (released on June 2, 2008) for Firefox 3, Safari 3, IE6 and IE7. The product, re-released as Google Earth in 2005, is currently available for use on personal computers running Microsoft Windows 2000, XP, Vista, 7, Mac OS X 10.3.9 and above, Linux (released on June 12, 2006), and FreeBSD. It is available under three different licenses: Google Earth, a free version with limited functionality Google Earth Plus (discontinued), which included additional features and Google Earth Pro ($400 per year), which is intended for commercial use. It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. Google Earth is a virtual globe, map and geographic information program that was originally called Earth Viewer, and was created by Keyhole, Inc, a company acquired by Google in 2004.
