Hallo there,
a year ago, I wrote a perl script, which makes vector 3D-Trees for GRASS
(5.1-5.7) 6.0.
The way, how the trees are done is following:
v.out.ascii points -> 3Dtrees -> LOCATION/MAPSET/dig_ascii/trees.ascii,tree-crowns.ascii -> v.in.ascii trees
It would be nice, if there was someone, who would test the script a bit and who
would let me know, what could be done better etc. I'm no programmer, this was
done just for some school work, but it works.
Some screenshots can be seen on

The script can be found on

Just run './trees-0.5.pl --help' to know the parameters.

Hello Listers,
I am having trouble with v.digit when trying to add attributes to newly
digitized points in grass6.0beta1.
After starting a new map with v.digit I added a new column to the table and
created the table. It was confirmed by grass that the table was created
successfully.
v.digit -n map=vectbugs bgcmd="d.rast bugsites"
Map does not exist.
New empty map created.
100%
cat integer , name varchar ( 50 )
But only on very rare occasions the attribute form opens after I digitized a
point. I also can not display the attributes of points or centroids.
Having said that, it seems to work everytime after booting the computer. Is
that the only way to edit attributes with v.digit, booting the system over and
over again?
I compiled grass6.0beta1 from source on a PC running Debian-GNU/Linux.
Thanks for your comments.
Cheers,
Robert

On Madrake 10.1 and 10.0 I'm having the same with any 6.0 version, both
precompiled and built from source, not only when digitizing points but any
features. However it works just ok on Mandrake 9.2, strange. I wonder
what other platforms suffer from this problem. Hey, anybody???
I also can not display the attributes of points or centroids.
Do you mean that d.what.vect in GUI mode doesn't work? That would would be
exactly what I'm struggling with. See a bug report:
http://intevation.de/rt/webrt?serial_num=2927 and let us know if you have
the same problem.

Developers know about this problem but were not able to reproduce it. You
can check the grass-devel for from Florian Goessmann's email from 26.01.05
17:03 containing a patch which propably *may* be a solution (though nobody
knows why it would work:)))). I'm going to try it tomorrow and will let know
how it works, didn't have time today.
Good luck and please let me know if find someway to get rid of it.

Checked the above patch and it worked so far in my GRASS-Sessions on
Debian/unstable.
Strange...
But anyway, thanks for giving the hint on this (rather simple) patch.
Cheers

No, I meant displaying attributes within v.digit.
But, I had the problem you described above using d.what.vect and got
around it by using the '-x' switch, so far.
Anyhow, the patch you mentioned works for v.digit and d.what.vect, as well.
Thanks for the pointer.
