SDO_GEOR.setGCPGeorefMethod

Format

SDO_GEOR.setGCPGeorefMethod(
     inGeoraster     IN OUT SDO_GEORASTER
     gcpGeorefMethod IN VARCHAR2);

Description

Sets the GCP-based georeferencing geometric model type of a GeoRaster object.

Parameters

inGeoraster

GeoRaster object.

gcpGeorefMethod

Georeferencing geometric model type to set for the GeoRaster object. Its value must be one of following strings: Affine, QuadraticPolynomial, CubicPolynomial, DLT, QuadraticRational, or RPC.

Usage Notes

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

If inGeoraster does not contain GCP-based georeferencing information, no action is performed; otherwise, the existing model type is replaced with the specified gcpGeorefMethod value.

The procedure just set the model type value; no new solution is calculated. To get the solution for the newly set model type, use the SDO_GEOR.georeference function.

Examples

The following example sets the GCP-based georeferencing geometric model type of a specified GeoRaster object, and updates the object.

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