A further test revealed that the PROJ.4 DLL was missing on my system. After downloading the current version included in OSGeo4W, and putting it in the gdalwin32-1.6\bin directory, I now get the correct results.

Thanks a lot, Howard!

Hi,

I have just installed GDAL 1.6.1.win32-py2.6 on a Win XP system and set
up the GDAL directory properly (bin directory in PATH, env variable
points to data).
Scripts for coordinate transformation like that below do not crash, but just seem not to do anything, i.e. the data remain unchanged instead of
being reprojected. Can anybody tell me what I am doing wrong?

The output is
POINT( 776041.000  3386618.000)
POINT (776041 3386618)
where I had expected lat/long instead for point.

Thanks a lot!
Klaus

Klaus,

I get the following for output on my OSX box:

POINT( 776041.000  3386618.000)
POINT (-84.121611219545073 30.5802861582041)


I suspect the TransformTo is failing because the GDAL_DATA are not
being found.

Howard
