I use d.zoom to set the extents I want for the project mapset and see the northern and eastern coordinates of this area. If I use g.region n=<values> e=<values> res=30 I assume that the southern and western bounds will be calculated as a round number of the resolution within the displayed window. Is this correct?
Searching my saved mail list threads I found the answer: v.in.region out=<region_name>. However, I have not found the follow up to this: now that I have defined my limited analytical region, how do I clip the large maps (and their associated attribute data) to this area? For example, there are almost 805,000 stream/river reaches in the state and many fewer in my area of interest; there are 4204 drainage basins (12-digit resolution) in the state and only about 18 within my analysis area. What command deletes everything outside the current region?
