•In order to maximize the visual contrast
between different crops in various states, colors that provided the best
contrast for the crop mix in a particular state are chosen. Some of the Midwestern States are dominated
by two main crops, while the Great Plains States may have up to 15 different
crop types and the Delta States may have four or more main crops. It is necessary to chose the best color mix
given the amount of crops that are grown in a state, and what kind of
contrast that you which to achieve.

•For instance, permanently assigning the color
yellow to corn for all states would limit the ability to contrast that color
with other crops within any given state.
Whereas a state that grew little or no corn, would be forced to use up
the yellow color, therefore, reducing the amount of contrasting colors.

•The color schemes chosen for the Towson
University sponsored Mid-Atlantic project are the same as the Midwestern
states because of the similarities in the crops that are grown.

•However, the digital numbers for each category
within every state are the same. So
corn in North Dakota will have the same digital number as corn in
Arkansas. See mastercat.htm in the
statinfo directory for a full listing by cover type.
