<br>
Tried to run the Grass tool using the example in the help below , but in QGIS I do not see a g.region method so how do I limit my area?<br>
<br>
# set computational region<br>
g.region raster=elev_lid792_1m -p<br>
<br>
# get center coordinates as an example<br>
g.region -c<br>
# get terrain height at point<br>
r.what map=elev_lid792_1m coordinates=638650.0,220375.0<br>
# shows elevation: 116.7734<br>
<br>
# generate tilted plane<br>
r.plane myplane30 dip=30 az=75 east=638650.0 north=220375.0 \<br>
elev=116.7734 type=FCELL<br>
<br>
Whe running it with the example input.<br>
<br>
r.plane sloping_plane dip=30 az=75 east=638650.0 north=220375.0 elev=116.7734 type=FCELL<br>
<br>
I just get a constant plane of the same height throughout, so not sure of that is an issue of not setting the region.<br>
