SDO_GEOR.setSpectralResolution

Format

SDO_GEOR.setSpectralResolution(
     georaster  IN OUT SDO_GEORASTER,
     resolution IN NUMBER);

Description

Sets the spectral resolution of a GeoRaster object if it is a hyperspectral or multiband image, or deletes the existing value if you specify a null resolution parameter.

Parameters

georaster

GeoRaster object.

resolution

Spectral resolution value. Must be null if the GeoRaster metadata does not contain band reference information.

Usage Notes

Taken together, the spectral unit and spectral resolution identify the wavelength interval for a band. For example, if the spectral resolution value is 2 and the spectral unit value is MILLIMETER, the wavelength interval for a band is 2 millimeters.

The GeoRaster object is automatically validated after the operation completes.

To return the spectral resolution for a GeoRaster object, use the SDO_GEOR.getSpectralResolution function.

Examples

The following example sets 0.5 as the spectral resolution value for the GeoRaster object (GEORASTER column) in the row with the GEORID column value of 4 in the GEORASTER_TABLE table. (The GEORASTER_TABLE table definition is presented after Example: Using storageParam Keywords in Storage Parameters.)

DECLARE
  grobj sdo_georaster;
BEGIN
  SELECT georaster INTO grobj FROM georaster_table WHERE georid=4 FOR UPDATE;
  sdo_geor.setSpectralResolution(grobj, 0.5);
  UPDATE georaster_table SET georaster = grobj WHERE georid=4;
  COMMIT;
END;
