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.
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; SDO_GEOR.GETGCPGEOREFMETHOD(GEORASTER) -------------------------------------------------------------------------------- Affine
