3. RASTER PROCESSING SUPPORT IN ARCGIS
ArcGIS provides sets of Geoprocessing tools that allow users to
create, analyze, and process raster data. Some of the tools such
as creating a slope, or creating a shaded relief from DEM,
performing raster data overlay, zonal and local analysis,
hydrology analysis, and so on are provided through ArcGIS’s
Spatial Analysis extension:

Some basic image processing tools, such as image clipping,
image mosaicking, compositing bands, and so on, are provided
through ArcGIS core products:

B ^ Raster Properties
The Create Pan-sharpened Raster Dataset tool is used to create a
pan-sharpened image by fusing a low resolution MS image with
a high resolution panchromatic image. The pan-sharpening
methods supported in ArcGIS include Brovey, HIS, Mean, and
ESRI methods. The two pictures (Figure 4 and Figure 5) below
