[GRASS-user] sqlite in grass7

Hello all, I'm trying to use an sqlite database for a vector file in a location created in grass 6.4 in grass7 but the only drivers listed are ogr and dbf. I thought that sqlite was to be the default database driver in 7 (http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures)? I'm sure this is

I think what you are looking for are the interpolarion tools. They can be found in the menu Raster, under interpolate surfaces Daniel On Fri, Jul 23, 2010 at 7:26 PM, Susana Arciniegas sarcinie...@mail.igm.gov.ec wrote: I found tool Tools for point layer (Herramientas para capas de puntos)/

[GRASS-user] Overlapping vector areas

Hi I am trying the generate watersheds for several outlets by looping over r.water.outlet in a python script (attached). The basin procedure is that for each outlet point (read using v.info -t), my script runs r.water.outlet, r.to.vect and v.patch, to combine the watersheds into a simgle vector

Re: [GRASS-user] Re: Installing r.area

fyi I get what it does now, and just fixed a small bug in it which was stopping it from reading CELL maps. I have the full svn version of grass built from source, and from the addons svn dir I built it with: make MODULE_TOPDIR=/usr/local/src/grass/svn/grass65/ (I just run grass out of the

[GRASS-user] Aquatic (Fish) Habitat Modeling with GRASS

I've not found a module or integrated tool to model aquatic (primarily fish) habitats by stream/river or drainage basin. I've looked at the Wiki and searched fairly extensively with Google and have not found anything useful ... that runs on linux or the *BSDs. Has anyone created such a tool

Hi everyone, Thanks for the responses. I'm really sorry that I'm struggling so much here, but... It just isn't working for me. Hamish: I tried building GRASS from source and failed miserably. I know, it must sound pathetic. I went through all of the packages that are required for GRASS -

[GRASS-user] r.terraflow problem

Dear GRASS users, I am trying to run r.terraflow in GRASS 6.4.0svn (GIS library revision: 37101 (2009-05-10)) provided as part of the OSGeo4W bundle on WinXP. The command prints some output, which looks normal, and then exits right away without doing anything. Here is the command and the output

Ricardo, This is not an answer to your question but rather a question to the list. Can v.db.update take as values a formula using data from other collumns? Or would I need to use db.execute to do something like new_column = col_A + col_B Daniel On Thu, Jul 29, 2010 at 4:57 PM, Ricardo Rodríguez
