SDO_GEOR.setRectified

Format

SDO_GEOR.setRectified(
     georaster   IN OUT SDO_GEORASTER, 
     isRectified IN VARCHAR2);

Description

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

Parameters

georaster: GeoRaster object.
isRectified: Specify TRUE to specify that the GeoRaster object is rectified, FALSE to specify that the GeoRaster object is not rectified, 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 rectify the object. Users are responsible for ensuring that rectification is performed. (To rectify or orthorectify a GeoRaster object, you can use the SDO_GEOR.rectify procedure.)

The GeoRaster object is automatically validated after the operation completes.

A GeoRaster object must be spatially referenced if you want to set isRectified to TRUE (see the SDO_GEOR.setSpatialReferenced procedure).

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 not rectified. (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.setRectified(grobj, 'false');
  UPDATE georaster_table SET georaster = grobj WHERE georid=4;
  COMMIT;
END;
