Instructions provided describe how to view IKONOS rasters in ArcGIS Desktop.
IKONOS rasters are stored with an 11-bit pixel depth. The range of values for the pixels of this raster can range from 0 - 2047. However, ArcGIS recognizes this pixel depth as 16-bit with a possible range of values of 0 - 65535. Because most of the values in the 11-bit range fall in the lower portion of the 16-bit range, the IKONOS raster will display as black to very dark by default in ArcGIS.
It may be necessary to first delete the raster's .aux file in order for this option to function properly. This file would be named FILENAME.aux, where FILENAME is the same name as the IKONOS Raster itself.
