I understand that GDAL/OGR includes the Proj.4 library, but I haven't found any documentation explaining how I can transform a textfile of NAD27 coordinates to NAD83 from a Python script. Can anyone point me in the right direction?
Jim, There is some information on GDAL/OGR coordinate system services (in terms of the C++ API) at: http://www.gdal.org/ogr/osr_tutorial.html You might also find the following python script useful as an example of coordinate system services: http://svn.osgeo.org/gdal/trunk/gdal/swig/python/samples/tolatlong.py Also, from the commandline you could use the following to transform a text file of NAD27 points to NAD83: gdaltransform -s_srs NAD27 -t_srs NAD83 < nad27.txt > nad83.txt Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, [EMAIL PROTECTED] light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
