Format

SDO_GEOR.getGCPGeorefModel(
     inGeoraster  IN SDO_GEORASTER 
     ) RETURN SDO_GEOR_GCPGEOREFTYPE;

Description

Returns all information about the ground control point (GCP)-based georeferencing model in a GeoRaster object.

Parameters

inGeoraster

GeoRaster object.

Usage Notes

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

The SDO_GEOR_GCPGEOREFTYPE object type is defined in SDO_GEOR_GCPGEOREFTYPE Object Type.

If inGeoraster does not contain any georeferencing model information, this function returns a null value.

Examples

The following example returns the GCP-based georeferencing model information in a specified GeoRaster object. (The output is reformatted for readability.)

SELECT sdo_geor.getGCPGeorefModel(georaster) FROM georaster_table WHERE georid=10;
