Hi all,
does anyone have a new(er) trick for negative vector buffers (in GRASS 7)?
thanks

You can query the white cells and discover that they are null values. This

No, but national data sets do.
The basin to the west of the top-most white area also does not include the
mouth of the main stem shown, but it's colored as a basin.

Hamish, Markus,
I have compiled the OpenCL code and got it to work with Grass70svn on Ubuntu
11.10, but it is severely memory constrained. Your map has to fit in your
video ram (1GB for me). You can't use memory partitioning unless you have
already run r.horizon, unfortunately, and
Daniel,
Wow, I may have done the math wrong, but I think you would need ~10GB of RAM
per r.horizon process to run your map without constraining the area. So, I
would be inclined to agree with Hamish that you may be RAM constrained. I
have had some success using g.region to tile my dataset
On one project the r.stream.extract error, Accumulation map does not

project the mask was removed, and no longer limits the DEM region.

I started over to ensure the elevation map was not masked. Because of the

Hello all,
I usually use v.surf.rst to build DTM from contour lines. However, this time I
have, in addition to the contour lines, a wide range of elevation points.
How can I use isolines and points at the same time to generate the DTM?
I thought a way to get around, which is to convert the
