I tried it with 5m and with 50m. The smaller window finds very small peaks and finds a lot of ridges. The larger window does a better job of finding peaks. But it tends to find major peaks (like inverted DEM and r.terraflow) rather than local ones. </div><div><br></div><div>The screenshots are for r.prominence run with a 50m window. Be forewarned it goes VERY slow with a large window and may take an hour or so. </div><div><br></div><div>Michael</div><div>____________________</div><div>C.
