Module Coordinate Transformation (Grid)

Coordinate transformation for grids.

Projection routines make use of the Proj.4 Cartographic Projections library.
Proj.4 was originally developed by Gerald Evenden and later continued by the United States Department of the Interior, Geological Survey (USGS).
Proj.4 Version is Rel. 4.7.1, 23 September 2009
