OGR_G_* functions are intended to operate on OGRGeometry objects while
OSR* functions operate on OGRSpatialReferences. Your hSRS object is an
OGRSpatialReference and not suitable to pass to OGR_G_ExportToWkt().
You should use OSRExportToWkt() to translate an OGRSpatialReference
into it's
WKT representation.
Best regards,
Thanks Frank.
This is also a result of my attempt to understand all the OGR model plus
inventing a way of wrapping it all inside a single StructureArray (the
C-MEX API). So let me ask one further question about the model. Is is
possible to have the case
Dataset --> SRS
--> Feature1 --> Geom1 --> SRS1
--> Feature2 --> Geom2 --> SRS2
--> ...
that is, different SpatialReferences inside the same Dataset?
Thanks
Joaquim
