[GRASS-user] mask problem

Dear users,

I’m working with a mask to cut the extent of my raster data (dem). I also have point vector data which lies also outside my mask.

Now I want to do the v.what.rast module to get elevation data into my vector data table. What can I do to also get the elevation data of the raster outside the mask??

Thanks,

stef

1. Be sure you have matched the "active" region to the queried raster.
E.g.: "g.region rast=dem", perhaps with "-a" flag

2. Remove the MASK! Alternatively, if the MASK is big and takes a long
time to rebuild, just rename it temporarily for example with "g.rename
rast=MASK,temp_MASK"

Then the points lying outside of the MASK should be updated as well.
Kind regards, Nikos
