[Gdal-dev] python CoordinateTransformation

[Xiaodong Zhang]

Thanks Frank and Howard,

It works. Just curious to know a little bit of CloneGeogCS() method, the 
description of which is not available from the gdal web. Is it designed 
to create a geographic projection (i.e., lat & long) out of the existing 
projection using the same, say, datum, etc.

Thanks again for your help.
