[GRASS-user] Icelandic / international characters in databases and ps.map

Hi, After initially being put off by seeing complicated scripts, I've started to use psmap. I wanted to use the postscript fill patterns to create a geological map that would reproduce in black and white. It's really good - the commands are pretty easy and the results look clear and excelle

Re: [GRASS-user] v.in.ogr problem

Hello Maris, Hello all! Problem solved (I have to put this on topic?) I'm not sure if the file I've tested is so big to GRASS, but I left the v.in.ogr working for a hole afternoon and nothing. So I tried a smaller data and still nothing. Then I did some search on the net and I found a tip that so

Re: [GRASS-user] Icelandic / international characters in databases and ps.map - SOLVED

Hi, Solved. Firstly, I had to compile grass with freetype (which I didn't have) and freetype includes. ./configure ... --with-freetype --with-freetype-includes=/usr/include/freetype2/ I backed up my vector (as peaks_iso), then, as described in the thread, I opened the its dbf file in Open

[GRASS-user] Averaging multiple vector lines

I have a GRASS vector that originated as multiple GPS tracks from walking a particular trail segment on several different days. Is there a good way to average these lines to get a single line? I want to minimize GPS accuracy errors by averaging across multiple days and also minimize precisi
