SDO_GEOR.getSpectralResolution

Format

SDO_GEOR.getSpectralResolution(
     georaster  IN SDO_GEORASTER
     ) RETURN NUMBER;

Description

Returns the spectral resolution of a GeoRaster object if it is a hyperspectral or multiband image.

Parameters

georaster

GeoRaster object.

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.

To set the spectral resolution for a GeoRaster object, use the SDO_GEOR.setSpectralResolution procedure.

Examples

The following example returns the spectral unit and spectral resolution for all spatially referenced GeoRaster objects (GEORASTER column) in the GEORASTER_TABLE table, whose definition is presented after Example: Using storageParam Keywords in Storage Parameters.

SELECT georid, substr(sdo_geor.getSpectralUnit(georaster),1,20) spectralUnit,
               sdo_geor.getSpectralResolution(georaster) spectralResolution
  FROM georaster_table
 WHERE sdo_geor.isSpatialReferenced(georaster)='TRUE';

    GEORID SPECTRALUNIT         SPECTRALRESOLUTION
