In addition to the form
below, you can:
- Expand the z range to use all the available colors on
the map window, which can be valuable when you have blown
up the map and no longer have the highest or lowest
locations on the map. This will only work if you have subset the
DEM, and will put the elevation limits for coloring based on the highest
and lowest elevations on the map.
- To arbitrarily set the color limits, right click on the elevation map,
pick "Elevation colors, Specify", and then select what you want
for the limits to use in coloring. These limits will then apply if
you switch to a reflectance map.
- Set the color range, useful if you want to match several

- Gray scale: a black to white progression.
- Alternate bands: contours displayed in
alternating color bands.
- Color bands

the saturation can be from the light

- Spectrum colors
- Automatic chloropleth palette
Coloring of grids by integer code
- Ocean check to put all points at
or below sea level in the water color.
- Lake check, to put lakes in the
water color. Only some DEMs are accurately
encoded and do well with the lake check.
- Set IHS colors.
- Set color for missing data.
- z Range:
set the values to use for color coding.
- If you use colors
from a table, you can specify the table with
the colors and their ranges. There can be a
maximum of 1024 entries in the table, which is a
dbf table. The easiest way to edit that file is
probably in Excel.
