hello Grass-users
I have come across this error message when using r.to.vect, and I'm afraid I
don't understand what it means (or how to solve it!)
r.to.vect -z input=Replace_test2@PERMANENT
...
Can you post the exact error message? Also, liblas support will only
be available if liblas-config exists.

Did anyone else get stuck here or am I missing something obvious?
Thanks for reading,

Rebecca,
The distribution and GRASS version has nothing to do with it.
The GRASS
and python-liblas
installed through synaptic and am wondering if there is a libraty package
missing?
Hmm. Is lasinfo --help working?
What does
liblas-config --libs
and
liblas-config --includes
say?

I have one question regarding i.rectify's data type output: If I have my
input is a CELL map, will my output will be also CELL? I mean, does it keep
my data type?
That depends on the resampling method. Only nearest neighbor
is calculated. This is the difference between the option order
and the option method. BTW, the option method has been introduced only
relatively recently, i.e. is not available in 6.4.1, I think, only
6.4.2.

Hi all,
the GRASS 7 vector topology format changed a bit. I have removed
redundant information (bounding boxes) from vector topology and
updated all affected components. The changes are numerous and require
make distclean
configure

This change also means that whenever you switch between
