Detailed Description

Perform geographic transformations between different coordinate systems and projections.

The "source" and "destination" coordinate systems and theirs projections need to be specified using the WKT representation. After that, one can transform points from "source" to "destination" and vice versa.

This class is a wrapper to the OGR library.
