SDO_GEOR.deleteControlPoint

Format

SDO_GEOR.deleteControlPoint (
     inGeoraster     IN SDO_GEORASTER,
     controlPointID  IN VARCHAR2);

Description

Deletes a ground control point (GCP) that has the specified control point ID value.

Parameters

inGeoraster

GeoRaster object.

controlPointID

Control point ID for inGeoraster. Must be a string not more than 32 characters.

Usage Notes

For an explanation of georeferencing using GCPs, see Ground Control Point (GCP) Georeferencing Model.

If the controlPointID is null, empty or not found in the existing GCPs stored in the GeoRaster object metadata, an exception is raised. If a GCP with the specified point ID is found, that GCP is deleted from the georeferencing model.

Examples

The following example deletes the GCP that has the ID value 23 in a specified GeoRaster object.

DECLARE
   gr1  sdo_georaster;
BEGIN
   SELECT georaster INTO gr1 from herman.georaster_table WHERE georid=10 FOR UPDATE;
   sdo_geor.deleteControlPoint(gr1, '23');
   UPDATE georaster_table SET georaster=gr1 WHERE georid=10;
   COMMIT;
END;
