I would do what Daniel said, but use the raster (use command v.to.rast) as a mask (use command r.mask) to limit the displayed area to the vector map area.<br><br><div class="gmail_quote">On Thu, Jun 30, 2011 at 9:40 PM, Daniel Lee <span dir="ltr"><<a href="mailto:Lee@isi-solutions.org">Lee@isi-solutions.org</a>></span> wrote:<br>

the raster data you want to show:<br>
<br>
1. Convert the vector to a raster with r.to.vect<br>
2. Reclassify it so that it's got only two values: 1 and NoData.<br>
3. Multiply the reclassified raster with the raster data that you want to<br>
limit to the area of the vector. The old values will be preserved in the<br>
resulting map because x * 1 = x, but everything that's not collocated with<br>
the vector map will be removed because it's multiplied with NoData.<br>
