Re: [GRASS-user] Location wizard error
In general don't be surprised if a generic linux build doesn't work properly on Ubuntu (or other distro) as location of system support files move about in an uncontrollable way. To avoid this kind of problems, what is your suggestion in order to update GRASS, using weekly snapshots? On Ubuntu 9.10/Karmic with the proj package installed the path to the EPSG file is /usr/share/proj/epsg. I've got the UbuntuGIS grass 6.4.0rc5 on ubuntu 9.10 running here, and the location wizard looks fine. Mine is pointing to: /usr/local/share/proj/epsg. I changed to your path and it worked. Question: Where do I define this path in order to change it automatically when I install/update GRASS?

[GRASS-user] r.to.vect Produces Too Many Areas
I've done something incorrectly but cannot find what that is. Ran r.water.outlet and produced the output basin map. Then I applied r.null to that map setting nulls to zeros. Next I applied r.to.vect to that map (with the '-s' option) setting feature to area. When I look at the aspect map overlaid by the sub-basin map I see the 5 extraneous cells that should not be there. You can see them on the attached screen shot. This did not happen the last time I used r.water.outlet, and the drainage map does not suggest to me why these 5 cells are included. Help would be appreciated in learning what happened and how to get this tail off the map.

Re: [GRASS-user] Question about least cost path
On Mon, 22 Feb 2010, M S wrote: Is the path terminating in local minimums? Mark, I don't know. It is my understanding that r.drain overcomes pits/sinks in a DEM by traversing lowest locations until goes off map. I did not use r.drain, but r.watershed. The last time I ran this sequence -- before correcting the reprojection and resolution -- there were no spurious cells.

To: grass-user@lists.osgeo.org Message-ID: 1266843609307-4611842.p...@n2.nabble.com Content-Type: text/plain; charset=us-ascii Is there no simpler way? e.g using the centroid as a center spot and then find the part of the polygon which is furthest away and use that distance for max radius? (and min dist for min radius) or make grass create a circle increasing in size untill it is fully outside the polygon then use that radius? Is this beyond GRASS? There must be a way using R - although I am still learning so I would be greatful of any instructions of how to do this in R (including which libraries to use) I may have to go to a R forum, any good ones? There are a few approaches that occur to me. One thing I think you'll need is a map showing just the centroid locations (as points). You can do this by using v.extract, eg: v.extract input map output=output map type=centroid Then you could use v.distance measure distance from the centroids to all the boundaries in the original map, capture this in a database table, and select the min and max associated with each centroid. A question for others in the list: if you use the -a flag in v.distance, from centroid to line, I presume the measurement from the centroid is to all nodes on the line?

[GRASS-user] Re: Bug or my fault?
Thanks Michael but I don't think this is the problem in my case, I am using the default DBF database, no DB connections required. Also remember that it all works well when I use TclTk as the GUI, and all works well when the number of DBF files in the mapset is less than approx 188. I haven't been able to find any other cause so far, but it could be Python related rather than GRASS, when I kill the GUI that hangs I get an error message to the effect that Python.exe is not responding. But why should the number of DBF files be relevant??? -- View this message in context: http://n2.nabble.com/Bug-or-my-fault-tp4609390p4614994.html Sent from the Grass - Users mailing list archive at Nabble.com. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] r.watershed: Interpreting Visual Output Map
When I read the man page for the visual output map of r.watershed I see that it's supposed to help me display results. I assume that it does this by coloring the accumulation of surface runoff with sub-basin sizes between 0 and the threshold value. When I display the map with d.rast.leg The color scale of the legend is blank. There are values from zero on the top to the threshold value at the bottom, but no colors are displayed. How am I to interpret this map? How does 'surface runoff accumulation with values modified for easy display' relate to minimum basin size? What are the units of surface runoff accumulation?
