Folks,

I have written a new article this morning on how to go about extracting
a small study area from a large map projected image, using map
coordinates to do the subsetting. Additionally, I demonstrate how to
create an image mask from the study area coordinates. You can find the
article here:

This work was supported by a donation to my web page. Donations have
grown to $325 for the month. I *greatly* appreciate the support.

Cheers,

David
