Those instructions and the version of GDAL they link to are very old. The GDAL project no longer provides windows binaries (link). You can install GDAL from gisinternals.com. Download gdal-19-1500-core.msi and GDAL-1.9.1.win32-py2.X.exe (replace 2.X with 2.7 if you have ArcGIS 10.1 or 2.6 for ArcGIS 10.0).
I'm trying to get the gdal/ogr modules installed. I've downloaded the gdal/ogr binaries and the python bindings, and put in a directory. I'm using the gdal version that is bunded with the ms4w package here:
After downloading I've pulled the various files out and created a gdal directory with the following directories: bin (the various gdal tools and dll's), data (gdal data directory), plugins (additional drivers like sde filegdb etc), projlib (files used by proj4), python (the python bindings)
In my script i add the plugins, bin, to os.environ['PATH']
after doing this I can successfully import osgeo.ogr, use the tools etc. No problem.
So now I add the 'import arcpy' line at the top of my script. When I do this my subsequent attempts to import osgeo.ogr give me this error:
_mod = imp.load_module('_gdal', fp, pathname, description) ImportError: DLL load failed: The specified procedure could not be found.
If I try to import arcpy after I've imported osgeo.ogr, python crashes. The crash creates a popup saying python.exe has stopped working, blah blah.
The details indicate the fault module Name is 'RasterDB.dll'
Anyone have a recipe for installing gdal/ogr so that it works with arcpy? Suggestions on how to arcpy and OGR to work in the same script?
