Hi Peppe,
Thanks for the feedback! As you know, I like the idea of formulas for the
regular buffer tool, and I like it even better here. I need to come up with
a general Class that supports these kind of operations that many plugins can
use.
It sounds like geology GIS has some of the more unique computational
requirements of any specialty. I like your other examples (flood plain, and
disease prevention) too. I have thought that it would be nice to have a
plume tool to supplement the buffer tools. Something that can incorporate
directional dispersion effects like wind and water. Any thoughts on this?
regards,
Larry
