mincolor implements a greedy coloring algorithm for coloring regions of a map so that no two adjacent regions have the same color.

It can plot and save the resulting map (via matplotlib imshow) or export a cptfile for use with the Generic Mapping Tools.

usage

./mincolor.py <ncfile>

Export the .cpt file:

./mincolor.py <ncfile> -e
