This section describes any special notes about SAP Sybase IQ support of spatial data including unsupported features and notable behavioral differences with other database products.
- Geographies and geometries – Some vendors distinguish spatial objects by whether they are geographies (pertaining to objects on a round-Earth) or geometries (objects on a plane or a flat-Earth). In SAP Sybase IQ, all spatial objects are considered to be geometries, and the object's SRID indicates whether it is being operated on in a round-Earth or flat-Earth (planar) spatial reference system.
- Unsupported methods –
- ST_Buffer method
- ST_LocateAlong method
- ST_LocateBetween method
- ST_Segmentize method
- ST_Simplify method
- ST_Distance_Spheroid method
- ST_Length_Spheroid method
