             Google Earth
• 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.
• It maps the Earth by the superimposition
  of images obtained from satellite imagery,
  aerial photography and GIS 3D globe.
            Release History
• Released as Google Earth in 2005,Availabe on
  Microsoft Windows 2000, XP, Vista, Mac OS X
  10.3.9 and above, Linux (released on June 12,
  2006), and FreeBSD.
• also available as a browser plugin (released on
  June 2, 2008) for Firefox, Safari 3, IE6 and IE7.
• 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. Google map.

•   Google Earth 4.3 - April 15, 2008
•   Google Earth 5.0 Beta - February 2, 2009
• Resolution available is based somewhat
  on the points of interest and popularity
• Most land (except for some islands) is
  covered in at least 15 meters of resolution.
• Melbourne, Victoria, Las Vegas, Nevada,
  and Cambridge, Cambridgeshire include
  examples of the highest resolution, at 15
  cm (6 inches).
          Search and DEM
• search for addresses for some countries,
  enter coordinates, or simply use the
  mouse to browse to a location.
• 3D images of terrain and buildings are
• digital elevation model (DEM) data
  collected by NASA's Shuttle Radar
  Topography Mission (SRTM).
• Many people use the applications to add
  their own data, making them available
  through BBS or blog
• 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).
   3D building and Street View
• 3D buildings and structures (such as bridges),
  which consist of users' submissions using
  SketchUp, a 3D modeling program.
• 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.
• 360°panoramic street-level views
            Ocean Imagery
• version 5.0 (February 2009) , the entirety of
  Google Earth's ocean floor imagery was updated
  to new images by SIO, NOAA, US Navy, NGA,
  and GEBCO.
• Google Ocean feature allows users to zoom
  below the surface of the ocean and view the 3D
  bathymetry beneath the waves.
• On April 14, 2009, Google added underwater
  terrain data for the Great Lakes.
   Wikipedia and Panoramio
• Geographic Web Layer integration with
  Wikipedia and Panoramio
• Wikipedia entries are scraped for
  coordinates via the Coord templates
• Panoramio is a geolocation-oriented photo
  sharing website.
              Sky mode
• In version 4.2, released August 22, 2007,
  Google Earth added a Sky tool for viewing
  stars and astronomical images
• Hubble Space Telescope
• web-based version of Google Sky
  available at
         Historical Imagery
• Introduced in version 5.0
• Traverse back in time and study earlier
  stages of any place.
• Very useful for research purposes that
  require analysis of past records of various
• Introduced in Version 5.0
• A separate globe of the planet Mars
• The maps are of a much higher resolution than those on
  the browser version of Google Mars
• 3D renderings of the Martian terrain.
• 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.
• high resolution panoramic images from various Mars
  landers, such as the Mars Exploration Rovers, Spirit and
  Opportunity, that can be viewed in a similar way to
  Google Street View.
 Coordinate System and Projection
• The internal coordinate system of Google Earth
  is geographic coordinates (latitude/longitude) on
  the World Geodetic System of 1984 (WGS84)
• Google Earth shows the earth as it looks from an
  elevated platform such as an airplane or orbiting
• The projection used to achieve this effect is
  called the General Perspective. This is similar to
  the Orthographic projection, except that the point
  of perspective is a finite (near earth) distance
  rather than an infinite (deep space) distance.
          Baseline resolutions
• U.S.: 15 m (some states are completely in 1 m
  or better)
• Germany, Switzerland, Netherlands, Denmark,
  U.K., Andorra, Luxembourg, Liechtenstein, San
  Marino, Vatican City: 1 m or better
• Czech Republic 0.2 m (Prague 0.1 m) Slovakia,
  Hungary: 2.5 m (medium resolution)
• 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
• U.S.: 1 m, 0.6 m, 0.3 m, 0.15 m (extremely
  rare; e.g. Cambridge and Google Campus,
  or Glendale)
• Europe: 0.3 m, 0.15 m (e.g. Berlin, Zürich,
  Hamburg), 0.1 m Prague
          Altitude resolution
• Surface: varies by country
• Seabed: Not applicable (a colorscale
  approximating sea floor depth is "printed"
  on the spherical surface).
        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 in form of a quiz, with hints of the updated locations.
  The answers are posted some days later in the same
           GPS integration
• read tracks and waypoints from a GPS
• A variety of third party applications can
  generate KML or KMZ files based on user-
  specified or user-recorded waypoints.
