Python interface to PROJ.4 library

 PROJ.4 performs cartographic transformations between geographic (lat/lon)
 and map projection (x/y) coordinates. It can also transform directly
 from one map projection coordinate system to another.
 .
 This is a Python binding to PROJ.4, it can receive coordinates as numpy
 arrays, Python arrays, lists or scalars. This module is optimized for
 numpy arrays.
