Comment (by David Smith):
Here is a link to GDAL's RFC for "Curve geometries"
[https://gdal.org/development/rfc/rfc49_curve_geometries.html RFC 49]
This required the following C API changes. I think we should make a
decision on each of these (should Django implement them) as part of this
ticket.
- OGR_GT_xxxx (for Geometry Type)
- OGRErr OGR_G_ExportToIsoWkb( OGRGeometryH, OGRwkbByteOrder, unsigned
char*) -- Proposed in [https://github.com/django/django/pull/17696 PR]
- OGRErr OGR_G_ExportToIsoWkt( OGRGeometryH, char ) -- Proposed in
[https://github.com/django/django/pull/17696 PR]
- OGRGeometryH OGR_G_Value( OGRGeometryH, double dfDistance )
- int OGR_G_HasCurveGeometry( OGRGeometryH, int bLookForNonLinear )
- OGRGeometryH OGR_G_GetLinearGeometry( OGRGeometryH hGeom, double
dfMaxAngleStepSizeDegrees, char papszOptions)
- OGRGeometryH OGR_G_GetCurveGeometry( OGRGeometryH hGeom, char
papszOptions )
- void OGRSetNonLinearGeometriesEnabledFlag(int bFlag)
- int OGRGetNonLinearGeometriesEnabledFlag()
