I have used GDAL before for raster analysis, but I have little experience with OSR. Does anyone have any ideas as to why this is not working? I have also run a script I found online called test_transformation_osr.py and it also produces errors when transforming between spatial references. In other words, there seems to be a problem with the installation or something was not installed that I should have installed. I installed gdal1.5.2 binaries on win32 xp OS system.<br><br>Thanks for the help.<br>Mike<br><span class="pln"><span style="font-family: monospace;"><br><br>import osr, ogr<br></span><br><span style="font-family: Courier New,courier,monaco,monospace,sans-serif;"># CREATE WKT STRING OF
