7.61 SDO_GEOR.getGCPGeorefMethod

Format

SDO_GEOR.getGCPGeorefMethod(
     inGeoraster  IN SDO_GEORASTER 
     ) RETURN VARCHAR2;

Description

Returns the ground control point (GCP)-based georeferencing geometric model type of a GeoRaster object.

Parameters

inGeoraster

GeoRaster object.

Usage Notes

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

If inGeoraster does contains valid georeferencing model information, it returns one of the following values: Affine, QuadraticPolynomial, CubicPolynomial, DLT, QuadraticRational, or RPC.

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.getGCPGeorefMethod(georaster) FROM georaster_table
  WHERE georid =10;
