This may go under the heading of "what I did with RR today."
We just received the California Department of Forestry map defining
the level of fire hazard: Red for Very High, Orange for High, Yellow
I wanted to get the fraction of the Very High area in our county.
To be sure of my code I started with a script to get the RGB values
under the mouse, using a MouseMove function.
To see this
go url "http://home.infostations.net/jhurley/RGBunderTheMouse.rev"
Unfortunately the map does not show pure colors so getting the ranges
for each hazard zone is messy. But this utility is useful in
exploring the range of colors.
