[GRASS-user] Re: Overlapping polygons and v.distance

2008-12-11 Thread Adam Wilson
I figured out a solution to my problem using R, which is posted below for any future user's benefit (though this is specific to my dataset, some changes will be needed). I would still like to know if it is possible in GRASS, though. Thanks, Adam ### This code intersects a set

[GRASS-user] raster data from one location to another

2008-12-11 Thread José María Michia
Hi list. Sorry for the very basic question. I can not find a convincing way to do it myself. I need to copy a raster map from one location to another. I've think this options: - use a intermediary format, like ASCII - use r.pack/r.unpack - copy manually the files needed. I think that the files

[GRASS-user] r.to.vect and then v.clean using tool=rmarea creates polygons instead of holes.

Hello Grass-Users, I'm having problems with this sequence of commands: r.to.vect -s input=lszone output=lszone10 feature=area v.clean input=lszone10 output=lszone10_clean tool=rmarea thresh=2800 Below is the output. Overlaying lszone and lszone10_clean, I see that there are large

[GRASS-user] osm data in grass

2008-12-11 Thread Torsten Eckart
Hallo, could someone give me a hint how to import osm data in to a grass location. The module v.in.osm what I download from http://kripton.kripserver.net/software/v.in.osm/v.in.osm-2007-07-14-00 gives not a good result: Reading from file /home/torsten/Arbeit/Gis/Daten/osm/heim.osm, writing to map

I followed your suggestion, but I'm still getting the same problem. It seems strange that v.to.rast would create a vector file that has flawed topology. Do you know of any alternative to v.clean with rmarea? Btw, I also tried to use v.generalize with a very small threshold and then v.clean.

Hi, AFAIK the v.in.osm is for the old API (0.4) of OSM. You can't use it for the current data. There are utilities to import OSM data to various formats checkout their wiki: http://wiki.openstreetmap.org/ But if you want GIS ready data derived from OSM, you can download shapefiles here:
