Glossary for Geospatial Science

RGBI:� A display method that converts an RGB raster set into an HIS raster set and then substitutes a fourth coextensive raster object for the intensity component before conversion back to RGB components for display. The object selected for the intensity component is generally of higher resolution than the objects selected for the RGB components and imparts a higher pseudo-resolution to the displayed image. (See also: HIS, RGB.)
