<DIV>Options</DIV>
<DIV> </DIV>
<DIV>1. use Qgis for digitisation and then save the finished product in a GRASS data set.</DIV>
<DIV>Qgis has many tools to help digitisation.<BR>2. You may also use OpenJUMP, for digitisation but it can save the finished vector as a shapele which needs to be imported in GRASS.</DIV>
<DIV> </DIV>
<DIV>I remember that a couple of years ago, this (Option 1) was in fact suggested to be by this list.</DIV>
<DIV> </DIV>
<DIV>Cheers</DIV>

Is there any other way to create a raster mask!
