Is Web Mercator same as WGS84?

Is Web Mercator same as WGS84?

Unlike most map projections for the sphere, the Web Mercator uses the equatorial radius of the WGS 84 spheroid, rather than some compromise between the equatorial and polar radii. This results in a slightly larger map compared to the map’s stated (nominal) scale than for most maps.

How do I convert local coordinates to WGS84?

How do I convert local coordinates to WGS84?

  1. convert the known lat/lon coordinate to a cartesian coord (easting,northing).
  2. determine the x and y differences between (1) and the local coordinate of that point.
  3. apply this coord difference to to each of the 3 corners local coordinate.

What is a WGS84 Web Mercator coordinate system?

WGS 1984 Web Mercator and WGS 1984 Web Mercator (Auxiliary Sphere) use a conformal projection that preserves direction and the shape of data but distorts distance and area. Published in 1569 by Gerardus Mercator, the Mercator projection was created for use in navigation.

Is WGS84 the same as lat long?

It means “latitude and longitude coordinates on the WGS84 reference ellipsoid.” In any case: No difference, just like everyone else is saying, except in the very nitty gritty details of how they are used.

Why is Web Mercator used?

The reason Web Mercator was suitable as the basis for early web mapping is that it creates a convenient square shape for the entire world if it is truncated at approximately 85° North and South of the Equator. Wherever you are on the map, up is due north, down is due south and west and east are always left and right.

How do you convert WGS?

How to convert to WGS84

  1. Select input / output spatial references.
  2. Input coordinates using decimal format.
  3. Click on the ‘Transform’ button to get the result.
  4. Your coordinates will be converted using the output spatial reference.

How do I get WGS84 coordinates on Google Earth?

  1. Open Google Earth.
  2. At the top, click Tools. Options.
  3. Click 3D View. Then, under “Show Lat/Long,” choose a display format.
  4. Click OK. Coordinates will be displayed in the lower right corner.
