This all looks fine.
And you said that the destination tiff was smaller than the original?
Can you display the tiff files?
Maybe it's some disk problem (in the log you sent last time, it seems
there was an error reading the file...)?

You are absolutely right. I was running it in a shared folder, and for some

Hi there,
At my location have 2 MAPSETS: Mapset Regional, with raster with 300m
SpatiaL Resolution and Mapset Urban with 5 meters Spatial Resolution.
I need to pass a LandCovermap from Mapset regional to my Urban mapset but I
need it in the same 5 meters Spatial Resolution instead of the original
Hi,
I have two vectors in GRASS:
road network - line
grid - polygon
I want to compute road density and append the attributes to the grid poly.
In QGIS I tried using the vector tools (sum line length) with
shapefiles and it works for small areas bu not for my full region.
Any ideas?

Hi Nikos
Thanks for your link. But besides that one, has anyone developed/tried a
segmentation algorithm from R or any other tool?
Thanks

GRASS GIS development is currently driven by a relatively
small number of people, some of them working on GRASS only
in their spare time. And most of them have their focus on
areas other than map production GUIs.
So your best bet to get new functionality into the system

That contains two maps: test_bool is empty (all cells are -32768),
while test_dist appears to be the output.

Hi,
A couple options:
1. convert lines to points and use v.kernel or v.neighbors
2. import lines into R, and use the density function from the spatstat package.
Then, sample the density rasters within your polygon of interest with
v.rast.stats, etc.
Cheers,

Thanks for helping me,
as you wrote I change
std::cout driver std::endl;
to:
std::cout driver std::endl;
And I got a zero value return . So my driver isn't set ?
Is the problem from the following lines :
setenv(DBF_DRIVER,dbf,1);

Dears, can I cut a 3d volume using a 2d (ok, 2.5d) surface?
interpolating wir r3.* gives me the results inside a rectangular
prism. can I use a surface (like topography) to remove the upper part
of the volume?
