SDO_GEOR.setOrthoRectified

Format

SDO_GEOR.setOrthoRectified(
     georaster         IN OUT SDO_GEORASTER, 
     isOrthoRectified  IN VARCHAR2);

Description

Specifies whether or not a GeoRaster object is orthorectified, or deletes the existing value if you specify a null isOrthoRectified parameter.

Parameters

georaster: GeoRaster object.
isOrthoRectified: Specify TRUE to specify that the GeoRaster object is orthorectified, FALSE to specify that the GeoRaster object is not orthorectified, or null if the GeoRaster metadata does not contain spatial reference information. Must be TRUE or FALSE (case-insensitive) if the GeoRaster metadata contains spatial reference information.

Usage Notes

This procedure modifies the GeoRaster metadata for the object. It does not actually orthorectify the object. Users are responsible for ensuring that orthorectification is performed.

The GeoRaster object is automatically validated after the operation completes.

To be set as orthorectified, a GeoRaster object must be spatially referenced and rectified.

Examples

The following example identifies the GeoRaster object (GEORASTER column) in the row with the GEORID column value of 4 in the GEORASTER_TABLE table as orthorectified. (The GEORASTER_TABLE table definition is presented after Example 1-1 in Storage Parameters.)

DECLARE
  grobj sdo_georaster;
BEGIN
  SELECT georaster INTO grobj FROM georaster_table WHERE georid=4 FOR UPDATE;
  sdo_geor.setOrthoRectified(grobj, 'TRUE');
  UPDATE georaster_table SET georaster = grobj WHERE georid=4;
  COMMIT;
END;
