The geographic reference is based on geographic coordinates in WGS84

Hi,
This does not really belong to my knowledge area but I'll have a try anyway.
Check what you have after reading the proj string instead. Here with Python
>>> from osgeo import osr
>>> spatialRef = osr.SpatialReference()
>>> spatialRef.ImportFromProj4("+proj=merc +a=6378137 +b=6378137 +lat_ts=
Hi,
I call OSRImportFromProj4 with
"+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0
+k=1.0 +units=m +nadgrids=@null +towgs84=0,0,0,0,0,0,0 +wktext +no_defs"
and with the returned handle i get the major and minor axis (
OSRGetSemiMajor/OSRGetSemiMinor). I would expect the b
