[GRASS-dev] GRASS r.neighbors

[chris carleton]

I've encountered another challenge with GRASS that I need some expert advice with. I want to run a neighborhood analysis on a few DEMs, but the options in r.neighbors don't quite seem to suit my needs. I want an analysis that calculates the average difference between the central cell and its neighbors (using that average as the new cell cat value). The idea is that I'll end up with an approximation of terrain 'ruggedness' by looking at average differences in elevation within a given neighborhood. Any suggestions would be welcome.
