Dear all,
I'm in need to start a study in a urban area in which the DTM (
https://en.wikipedia.org/wiki/Digital_elevation_model) is to be obtained
from a DEM (SRTM or ASTER).
I've seen GRASS7 can provide DTM from LiDAR maps, but I'm afraid it won't
work in this case.
So, how to derive a DTM

Hello everyone,
I've got this prompt in transforming my vector line map (only branch/
multi-arc) into a network as the first step to perform v.net.path, to earn
my line map's arcs and nodes sorted one-way from one end to the other.
However, executing v.net.path gives no results, stuck in the
Hello everyone,
I georefered several RADAR GIF from a desired storm in my research and
realized there are some numbers set as an attribute in the pixels, beside
the pixel RGB color.
I found GIF generally is an option to export original CAPPI and PPI RADAR
images.
Such original RADAR images
values (dBZ), or precipitation amounts, or wind velocities — not to
mention what the units of the data. This
would come from the metadata of the data you are using.
More information is needed.

That was an incompatibility in v.to.rast after latest improvements there.
Fixed in r62202.
Please update your r.basin installation and this error should be gone.

Dear all,
indeed all dependences of r.basin are in the new GRASS core.
For now, r.basin gets raster drainages plus other raster and two vector
maps, that is, output point and snap point. The basin vector map is said to
be invalid (as shown beneath in footer).
Besides, prompt returns some

Dear all,
in the addon r.basin, the help says that basin output coordinates must
be picked up from some vector feature, the river network, which is
generated by the addon r.stream.extract.
That means I have the utm elevation raster and successfully ran

Well, anyways, it looks like no GUI is present. The following error

Hey you,
I have proceeded the Grass-7.0 install.sh successfully. However, when
executing 'grass70' I've got an Python error which made GUI impossible
to startup.
please, some of you know how to troubleshoot such error (Ubuntu 13.10
have both Python 2.7, 3.2 and 3.3 installed)?
