Re: [GRASS-user] Importing .csv table into GRASS
Hi everybody, thanks for suggestions; In between I've posted some comments and wondered why there was no answer to them - now I realized that I've simply replied to the people sending the comments, not the grass-user forum. Sorry for the confusion. Here, once more, I attach what I wanted to write to the grass user forum: 2-nd mail (reply to Moritz): Actually, the .csv table was made from .dbf table of an existing vector map. The problem is that I want to use v.db.join to transfer one attribute from that table to another vector map through a common key; When I tried v.db.join directly on the .dbf table, it said the .dbf format is not supported. I am affraid v.in.ascii will produce a .dbf table, so it does not serve my purpose. 3-rd mail (reply to Hamish): Thanks for suggestions. In between I took a way of least resistance and achieved my goal by a couple of OpenOffice Calc operations directly on .dbf files (instead of using db.in.ogr + v.db.join). However, the method of using this sequence of commands (db.in.ogr + v.db.join) is recommended and used in an example in Neteler, Mitasova, 2008: Open Source GIS and GRASS GIS Approach (Third Edition) - page 180. Therefore, I would like to find out what's the problem - is there a bug in the GRASS modules, or my .csv file in not OK?

[GRASS-user] grass 6.4 rc5 and python scripting
Hello list I compiled grass-6.4.0RC5 (downloaded a tarball from the main site). I'd like to learn about scripting grass with python.

Sorry for misleading you. Concerning the issue of dbf, GRASS will create the table in the default database backend that you define with db.connect, so just define sqlite as your default database backend, and it will create a table in an sqlite db which you can then use for v.db.join.

Re: [GRASS-user] grass 6.4 rc5 and python scripting
Hello all Thanks for your good advice. I decided to go with the option of EXPORTing the grass addon path and put my scripts there, which works ok, well... kind of. It happens that when I launch GRASS from the terminal, the GRASS_ADDON_PATH gets correctly added to the PATH and I can load my test script. However, if I start GRASS from the gnome menu (or gnome-do) the GRASS_ADDON_PATH gets ignored. Maybe theres some config file that I have to tweak?

[GRASS-user] link to datasets from other locations?
Hello grass users, There exist v.external and r.external to link to data which hasn't been imported into GRASS. But in order to save time and disk space I would like to link to data sets from other locations: How do I link to a raster and vector data in another location presuming it has the same projection?

[GRASS-user] Multiple v.net.path parameters
Hello, I am looking to use v.net.path to determine the distance of many different points to many different other points on a network. Is it possible to send multiple parameters to v.net.path? For instance, I have (in theory) 4 points connected to a network. I want to find the distance of the line segments between points 1 and 4, 2 and 4, 3 and 4. I want to: run v.net.path once by passing multiple parameters; get vector line output of each of these three paths found by v.net.path in one output file; calculate the distance of each line from the file using v.to.db. Since this is not a module of GRASS which I have worked with in the past, I am wondering if this is possible.

Re: [GRASS-user] Multiple v.net.path parameters
Well, I will have a database with thousands of points and I don't want to create thousands of vector files. Plus, I'm worried I will lose the length data if I use v.patch, which is what I am most interested in. I will contact Daniel. Thanks for the tip.
