[fdo-users] Re: ArcSde provider unsupported geometry type

[Dan Stoica]

Yes, FDO has such utility, see FdoSpatialGeometryConverter.h.

The application has to create a concrete class, an easy task, see for example:

// Implementation class for abstract FdoSpatialGeometryConverter class.
// No X and Y ordinates swapping.
class FdoRdbmsSqlServerSpatialGeometryConverter : public FdoSpatialGeometryConverter
{
public:
   FDO_SPATIAL_API void ConvertPosition(
        double &x,
        double &y) {}

    FDO_SPATIAL_API virtual void ConvertPosition(
        double &x,
        double &y,
        double &z) {}
};


Then the usage goes:

    FdoSpatialGeometryConverter *gc = new FdoRdbmsSqlServerSpatialGeographyConverter();
    FdoPtr<FdoIGeometry> geom2D = gc->ConvertOrdinates( geometryToConvert, true, FdoDimensionality_XY, 0.0, 0.0);
    delete gc;

Looks like the content of the geometry is only XY anyway; is there anyway to strip the ZM on the way in?  If not, some CAST-style operators would be useful...

It's even a little bit more restrictive, WKB is 2D only:

       throw FdoException::Create(FdoException::NLSGetMessage(FDO_NLSID(FDO_10_UNSUPPORTEDGEOMETRYTYPE)));


Giorgos, what do you need the WKB for?
