Hello!
I've recently started using GRASS and finding it very cool. The only
other GIS software I'm familiar with is QGIS.
Today's newbie question is how to clip a raster using a vector having
polygon geometries? Judging by the docs, r.mask should be used with
"vector=..." parameter. The command "r.mask raster=big_raster
vector=smaller_vector" was successful, mask was created. However, when
"big_raster" was added to the map layers in GUI, it was rendered in its
entirety, without getting clipped. An operation such as r.to.vect on
big_raster also resulted in the entire raster being used.
What am I missing? Are there examples illustrating the use of "vector="
parameter in r.mask?
