| SE_coordref_vertcs_get_id | |
Returns the vertical coordinate system ID for the supplied coordinate reference object
LONG SE_coordref_vertcs_get_id (SE_COORDREF coordref, LONG vertcs_id);
| coordref | A pointer to the coordinate reference object |
| vertcs_id | The predefined Projection Engine ID |
Returns the vertical coordinate system ID for the supplied coordinate reference object. The vertical coordinate system is identified by the predefined Projection Engine object ID. There are about 100 predefined vertical coordinate systems; see the pedef.h file for a complete list. If the vertical coordinate system is of type unknown, the returned vertcs_id is zero. If the vertical coordinate system is user-defined, the vertcs_id is returned as -1.
