Agreed. You have to make sure you have valid training areas are for each
image you want to classify. I've also found that dealing with clouds and
their shadows is one of the biggest issues to consider when doing
classifications.

Hi Micha, yes, by all means, wiki away :-) I haven't yet educated myself
on how to contribute to wikis and bugzillas and the likes, so if you

You are right Glynn, I just checked i.spectral.py and it has the
d.linegraph feature but, i.spectral is greyed out in wxpython gui and,
when I try to run it from the command line (using Msys wingrass7svn),
if I input a raster group I get the error:
GRASS 7.0.svn i.spectral.py group=alos.radiance

Dear list,
I just realized that there are some problems with the filter functions
used to do the atmospheric correction for the Alos AVNIR2, Ikonos and
RapidEye sensors. I expect to fix some of those bugs this week so
please, use i.atcorr with care if you work with these sensors.
Sorry for the
In order for GRASS to run properly, is it necessary for the grassdata folder
(database) to reside at the disk prompt (as in C:\grassdata)? I would rather
have it higher up [farther down?] in the hierarchy, such as
C:\GIS\placename, because it is more intuitive to me that way.
However, when I try
Hi All,
I am having similar problems to Kaipi in regards to the v.lidar.growing
stage of LiDAR processing. I'm running GRASS 6.4.0 on Windows. My dataset is
a 1km by 1km tile of LiDAR with a point spacing of about 1.5 points/m2, so a
total of about 1.5 million in the area of interest.

These are separate layers with no duplicate points. I have tried it with
several layers, in multiple projects. Only one gave results, and that was
relatively quickly. I the coordinates in sqlite, there should be no distance
