Hello
We are looking to mimic, in R, the slope (max magnitude difference
between a cell and its neighbors) and aspect (direction of maximum
magnitude difference) functions found in ESRI's Spatial Analyst package.
We were just about to code up the slope function but thought I would
make sure we weren't re-inventing any wheels already out there.
Thanks
Josh
