I have been trying something like this some time ago, but I could not define region of a mapset as chunk of the whole region. <div>I was trying to do that with g.region, but it only resized my map and didn't "cut" it.</div>
<div><br></div><div>Is g.region the right tool for this task? </div><div>If it is not difficult for you, can you, please, explain the process of doing " <i>define the region of each mapset as a chunk of the whole region</i> " a bit more detailed.</div>
