Module Geographic Coordinate Grids

Creates for a given grid geographic coordinate information, i.e. two grids specifying the longitude and latitude for each cell. The coodinate system of the input grid has to be defined.

Proj.4 was originally developed by Gerald Evenden and later continued by the United States Department of the Interior, Geological Survey (USGS).
