Hi,
nearly everybody would be interested, but nearly nobody has own time
for help. In case, nobody should write you directly, just have a look
at GRASS modules examples, they are IMHO very illustrative:
http://trac.osgeo.org/grass/browser/grass/trunk/doc/vector
http://trac.osgeo.org/grass/browser
import the ascii table with v.in.ascii [1]
store the values from raster to the new vector file database with
v.what.rast [2]
[1] http://grass.osgeo.org/grass64/manuals/html64_user/v.in.ascii.html
[2] http://grass.osgeo.org/grass64/manuals/html64_user/v.what.vect.html

try using d.shademap
Dear all,
I have a raster map on GRASS and a table (in ascii format) with XY
coordinates.
I would like to know how can I import these XY points in my grass database,
and
hown can I proceed to overlap my points over my raster map and aquire the
raster value
as an attribut of my XY points.
Any help
We've updated/fixed/improved starspan over the past few months, and even
began to create a grass interface for it:
http://starspan.casil.ucdavis.edu/doku/doku.php?id=grass
Unfortunately, our amazing programmer Carlos Rueda has left for greener
pastures (congrats to Carlos on his new job!), so
Nikos:
Have you checked out any of the new minirasterstrip features in
starspan yet? It takes vector data (any format that OGR supports),
extracts a window (user defined size) around the vector out of a set of
rasters (anything that GDAL supports), compiles it into a single image,
and ref

Apologies for cross-posting.
Can someone tell me why I should NOT use GIMPs "Fuzzy Select" tool to
select various "features" from an image (e.g. orthophoto), save
selection in a new file, add geo-metadata from the original image [1]
and continue my work in GRASS? It works so nice!
Could a tool l

Performing relative radiometric normalization is a *requirement* of
applying a single classification to multiple images (also for change
detection). Unfortunately, it is not an algorithm that is available (to
my knowledge), out-of-the-box, on ANY remote sensing platform (GRASS,

hello users!
i want to use v.digit with two overlayed raster maps, both of which cover
the entire area i'm working, so i need the raster "on top" be translucent to
some extent (say, %50 opacity)
is there a way to do that with the bgcmd argument of v.digit?
thank you all,
Juan

How could I use i.smap to perform segmentation on an image (e.g. aerial
photo) and get the segment only? Unfortunately I don't have now the
GRASS-book with me in which, I remember, there was a reference about
that.
Thank you,

After examining the mosaic I found multiple and big differences. I
conclude that the producer did not perform any radiometric nor
topographic corrections. It is a collage and not a mosaic :-)
Is this the way it should be?
Thank you,
