[Gdal-dev] types common to raster/vector

[Ray Gardener]

I was wondering if the following OGR types:

   OGRSpatialReference
   OGR_SRSNode
   OGRCoordinateTransformation
   OGREnvelope
   OGRRawPoint

would be better placed in their own lib/namespace, since they are often 
used in raster routines when doing georeferencing (or put another way, 
there's nothing particularly vector-specific about coordinate 
transforms). The OGR area could then be more pertaining specifically to 
shapefile specifics, and it would let raster-only projects more easily 
declude OGR.

e.g., a C++ decl might be:

   namespace spatial
   {
     class coordsys             { ... };
     class coordsys_node        { ... };
     class coordinate_transform { ... };
     class envelope             { ... };
     class point                { ... };
   }

For backwards compatiblity there could be:

   typedef spatial::coordsys              OGRSpatialReference;
   typedef spatial::coordsys_node         OGR_SRSNode;
   typedef spatial::coordinate_transform  OGRCoordinateTransformation;
   typedef spatial::envelope              OGREnvelope;
   typedef spatial::point                 OGRRawPoint;
