public class TLcdPseudoMercator extends TLcdMercator
Pseudo-Mercator projection.

Introduction Link icon

Cylindrical conformal projection.

Properties Link icon

  • The projection is conformal.
  • Meridians are equally spaced straight lines. Parallels are also straight lines but they are unequally spaced.
  • The scale of the projection is true along the equator.
  • Loxodromes (rhumb lines) are shown as straight lines.
  • The poles are at infinity, there is a great distortion of area in the polar regions.

Implementation aspects Link icon

This is a variation of the Mercator projection that is used by popular mapping applications such as Google Maps or Microsoft Bing. Functionally it is identical to the Mercator projection, except that it assumes a spherical ellipsoid. For this reason errors of up to 800 metres in position and 0.7 percent in scale may arise.
