[gdal-dev] GDAL python API - Data axis to CRS axis mapping

Hi

I am using the GDAL python API and trying to determine the data axis to CRS axis mapping.  This is displayed by gdalinfo, eg looking at test.tif file I have:

Data axis to CRS axis mapping: 2,1

However I can't see how to access this in the API.  I have looked at the tolatlong.py sample, and but this looks like it is about converting projections, which I think is a different thing.  What I am looking for is the correct mapping from the lat/lon order generated by the geotransform to the order defined by the CRS WKT.

Can anyone advise on how to best access this mapping?

Thanks
Chris Crook
