Is there a way to get a subset of a larger raster map. I have zoomed into an area and would like to make a raster map only containing that area. Can I do this? I am going to use this as input into R for some topmodel runs.
Stephen, Yes, you can. This subject has come up several times in the past month or so so the archives have a lot of options for you. One to look at closely is v.in.region. After zooming to the area you want, run v.in.region and save that vector map. You can then use it with the g.region command to limit the displayed bounds of your raster map. You can use r.patch to make a new raster map that's the size of the newly created vector map. Are you aware of r.topmodel within GRASS?
