Re: [GRASS-user] starspan with grass support compilation failure
Hello Nikos, probably create a trac wish report Investigate Starspan integration possibilities into GRASS. It can be used also later as meta bug to track integration blocking code bugs. I haven't used Starspan and currently have no requirements to do so, still integrating various small projects into larger ones is a good thing - lessens work fragmentation and improves code handling - any GRASS dev can poke around that code.

Re: [GRASS-user] starspan with grass support compilation failure
Speaking as a user... I used starspan a couple of times and it's great. But what I most liked about it is that _it works outside of GRASS_! It's independent of GRASS, so an user with just a shapefile and some GeoTiffs can use it happily. At the same time that I believe it's a great tool and it should receive more attention, the ability to work with other formats and outside of grass is very important. Maybe have something like the gdal tools, where the user can transform and query any image outside grass but also, it works inside the GIS. I say this because I had several grass rasters that I needed to do a zonal stats with a very big shapefile. I was having a hard time importing the shapefile into grass so, starspan to the rescue! Fast and simple.

[GRASS-user] using v.net.path output to update original map
I have a problem that I not sure how to correctly address. Basically I have vector map and I find some shortest paths on it using v.net.path. I basically want to keep track of which lines have been using in the shortests paths and how many times. So I suppose I need to add a column to original map called traversed, which starts at zero, and is incremented by one every time that line is used in a shortest path. So I have a vector map output from v.net.path, which contains a single attribute, and have option of the vector map being a single line, or the lines which were in original map. Is there a way to match the lines in the original map with the lines in the shortest path, and update the traversed attribute for that row in the original map? Would I have to add traversed column to shortest path map, get value from original somehow, increment, and then merge vector maps? Any ideas would be appreciated. Thanks. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] no output when running i.atcorr
Hi all, I want to do an atmospheric correction of my Landsat ETM+ images using the i.atcorr module in Grass 6.3 on Ubuntu, but I never get an output. When I use a DEM in *ialt*, the continuous version or the categorized, of the region, I just get wavelength less than 0.25 micron let's take s(1)=s(0.25). I don't insert an altitude value in my *icdn* file however, since I've read that that value would overwrite the DEM. When I do put in an altitude value, I get a list with the parameters for the 6S-algorithm, and then 'percent complete', so that seems to be ok, but the algorithm stops running, so I don't get a corrected image. Does anyone have experience with this module, and help me with some tips, preferably so I can use my DEM instead of one altitude value for the whole image? This is my *icdn *file when I use the DEM: 8 2 12 08.500 +35.2203028 -2.8893705 1 0 -1 -1000 64 and this when I use one altitude for the whole region: 8 2 12 08.500 +35.2203028 -2.8893705 1 0 -1 1000 -1000 64 Thanks in advance!
