We are working with an array of classification data, where each array element
corresponds to a particular class of some classification system (e.g. land
cover type). It is not a continuous field so it is not appropriate to contour
the field (i.e. class 5 does not necessarily occur between class 5 and 7 in
the field). We want to use the NCAR graphics package to assign a color on a
map to each array element which corresponds to a particular class number.
Is there a way to do this?
