Dylan,
I used r.param.scale extensively; will learn

Filter the input data with r.neighbors[1], r.mfilter, etc.
[1] I wouldn't use method=mode if you're going to calculate
derivatives. I'm not so sure about method=median either.
I appreciate learning of options that did not strike me as appropriate

run eg 'r.neighbors method=mode' to smooth/denoise maps
'r.param.scale param=feature' also offers a simplified version.
both modules allow you to change the search window size. the bigger the
window, the more smoothing.
