- This disk contains several demo files that may be of interest :
-
- 1. VGAFC : A file that illustrates the possibility of creating false color
- composites for 16-color VGA systems. View it using COLOR and the VGAFC
- palette, without a legend. This imge was created by creating a normal
- composite, clustering the result to 16 levels (fine clusters), stretching
- each of the original bands to 64 levels, crosstabing the clusters
- against these stretched image and noting the peak frequency grey level
- for each cluster, and using these to create a 16 leel palette. For those
- with 8514A systems, compare the result to BRAZILFC using a false color
- composite.

- 2. AFSURF : A file that illustrates the combination of hillshading with
- orthographic display. View it with COLOR, greyscale palette and no
- legend. A dense terrain model was subjected to the hillshading option of
- SURFACE and subsequently stretched to 16 levels. This was then draped
- onto the original terrain model and the resulting was was "dumped" with
- the "s" (save) option of ORTHO.
