7.62 SDO_GEOR.getGCPGeorefModel
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.
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;
