What is Google Earth CRS? The Google Mercator CRS allows any location on the globe to be represented as X-Y coordinates.
What CRS is used by Google Maps?
Google uses Google Mercator projection. EPSG:900913. For proj4 settings see here.
Is Google Earth NAD83 or NAD27?
Step 3: Google Earth's Datum is WGS-84, not NAD-27. We need to convert the map's NAD-27 Latitude & Longitude Coordinates to Google Earth's WGS-84 coordinates.
Why does Google use Mercator?
A Google employee explained in 2009 that the company used a Mercator map because it helped preserve angles of roads: “The first launch of Maps actually did not use Mercator, and streets in high latitude places like Stockholm did not meet at right angles on the map the way they do in reality.”

Is WGS 84 a projection system?
The North American 1983 datum (NAD83) uses the Geodetic Reference System (GRS80) ellipsoid while the World Geodetic System of 1984 (WGS84) uses the WGS 84 ellipsoid. For example, the “WGS84 projection” is a geographic one. A UTM projection is a projected one. Either of these will use only one datum.
Is Google maps based on Mercator projection?
World coordinates in Google Maps are measured from the Mercator projection's origin (the northwest corner of the map at 180 degrees longitude and approximately 85 degrees latitude) and increase in the x direction towards the east (right) and increase in the y direction towards the south (down).
What is WGS84 pseudo-Mercator?
Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications. It rose to prominence when Google Maps adopted it in 2005.
What projection is Openstreetmap?
Spherical Pseudo-Mercator projection
Most of OSM, including the main tiling system, uses a Pseudo-Mercator projection where the Earth is modelized as if it was a perfect a sphere. Combined with the zoom level, the system is known as a Web Mercator on Wikipedia.
Where does Google Earth Pro get its elevation data?
Google Earth uses digital elevation model (DEM) data collected by NASA's Shuttle Radar Topography Mission (SRTM) enabling 3D view of the whole earth.
Is Google Earth Pro reliable?
PROS: Google Earth Pro is an indispensable tool for professionals who deal with geospatial data. It is the most accurate source of maps, 3D images, and coordinates.
What is the elevation in Google Earth?
Check the altitude of a place
Search for a place, or adjust Google Earth until you get to the view you want. At the bottom right find the real-world altitude and the altitude of the camera. If you move the mouse to hover over different locations, the altitude updates.
