| SE_coordref_get_id | |
Returns the coordinate system ID for the supplied coordinate reference object
LONG SE_coordref_get_id (SE_COORDREF coordref, LONG *coordsys_id);
| coordref | A pointer to the coordinate reference object |
| coordsys_id | The predefined Projection Engine ID |
Returns the coordinate system for the supplied coordinate reference object. The coordinate system is identified by the predefined Projection Engine object ID. There are over 3400 predefined coordinate systems; see the pedeff.h file for a complete list. If the coordinate system is of type unknown, the returned coordsys_id is zero. If the coordinate system is not formally defined, the coordsys_id is returned as -1.
