Re: [GRASS-user] Rendering labels in GRASS Cartographic Composer from vector layer
It appears I can set the label size (map units) from the command line and the label re-sizing works as expected (provided I omit the fontsize option). However, I can't seem to omit the fontsize option if running from the module window. E.g. this works for a lat long layer, input in the command console, where the labels change in size on zooming. v.label labels=hydro_africa_lables.lbl map=hydrobasins_africa@hydrolayers column=MAJ_NAME size=0.25 color=red -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Rendering-labels-in-GRASS-Cartographic-Composer-from-vector-layer-tp5048403p5048538.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] v.label.sa not working with areas?
Hi, I'm using GRASS 6.4.3 and cannot get v.label.sa to work with areas. On running the following I get an empty labels file. v.label.sa --verbose map=hydrobasins_africa@hydrolayers type=area column=MAJ_NAME labels=africa_basins_sa font=Trebuchet_MS size=0.5 color=red However, it works with lines - I can output a labels file if the layer comprises line features.

Re: [GRASS-user] speeding up v.clean for large datasets
On Sat, Apr 20, 2013 at 3:02 AM, Mark Wynter m...@dimensionaledge.com wrote: Thanks Markus. Upgraded to GRASS 7, and re-ran v.clean on same OSM Australia dataset. Substantially faster. The bulk of the time related to removal of duplicates, and it got exponentially slower as the process approached 100%. Overall it took 12 hours but I'm wondering how it would perform if we were to repeat v.clean for even larger road networks e.g. USA or Europe? Something is wrong there. Your dataset has 971074 roads, I tested with an OSM dataset with 2645287 roads, 2.7 times as many as in your dataset. Cleaning these 2645287 lines took me less than 15 minutes. I suspect a slow database backend (dbf). Try to use sqlite as database backend: db.connect driver=sqlite database=$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db Do not substitute the variables. HTH, Markus M I'm tempted to try dividing the input dataset into say 4 smaller subregions (i.e. vector tiles), and then try patching them back. I read that we will still need to run v.clean over the patched datasets to remove duplicates. Since the only duplicates should be nodes along the common tile edges, is there a way to in effect constrain the v.clean process to slithers containing the common edges? I've had a quick go at g.region but to no avail.

We're running on a large Amazon AWS EC2 instance. What we've observed is exponential growth in time taken as number of linestrings increases. This means it's taking about 3 days to clean entire network. We were wondering if we were to split the dataset into say 4 subregions, and clean each separately, is it then possible to patch them back together at the end without having to run v.clean afterwards? We want to be able to run v.net over the entire network spanning the subregions. Alternatively, has anyone found a way to speed up v.clean for large network datasets? Yes, implemented in GRASS 7 ;-) Also, when breaking lines it is recommended to split the lines first in smaller segments with v.split using the vertices option. Then run v.clean tool=break. After that, use v.build.polylines to merge lines again. Or use in GRASS 7 the -c flag with v.clean tool=break type=line. The rmdupl tool is then automatically added, and the splitting and merging is done internally.

[GRASS-user] GDAL libgdal1.6.0.so.1 error (REPOST)
I am reposting my question because the first time I forgot to suscribe and the message was not sent to the mailing list. Sorry for the inconvenience. Hello everyone, I am trying to use GRASS backend with 52norh WPS server, so I have followed this instructions (http://52north.org/communities/geoprocessing/wps/tutorials/WPSGRASSLinux.html) to install GRASS 7 in ubuntu 12.10.

[GRASS-user] Unix and Grass commands in Windows
Hi Folks Just wondering how best to execute Unix and Grass commands using Grass 6/7.0. I'm running Windows Vista, and had started installing Cygwin, but this seems to be massive, and not even sure if this is the best environment, as some users don't seem happy about it. I had initially thought I could use the Console window, but this appears not to accept Unix commands. I also tried the included MySys Unix console which appears to be a Bash shell, but this does not recognise Grass commands. What would you recommend is the best option if I want to use Grass quite a lot, but don't want to convert my PC to a fully fledged Linux system (unless that really is the best option, such as using an emulator).

Re: [GRASS-user] Unix and Grass commands in Windows
Consider the option to install a virtual machine running Linux. Gives you the best of both worlds. You might choose the OSGeo Live DVD as your source for the virtual machine. It runs Xubuntu, and you'll have right from the get go GRASS 6.4 all the other GIS software you could want. You'll find instructions on how to setup the Live DVD as a virtual machine (with VirtualBox) right in the help files on the DVD. And after install the "Guest Addons" in the new VM, you'll be able to share folders between the VM and the host Windows computer, so you'll have access to any results from your Linux GRASS work back on the Windows machine.

Thanks Micha I'll have a look at this. I am trying to optimise the number of applications on my system to have a limited number that I can actually use, yet cover all evils!!

Would like to get everything on a modest laptop, or even a subset of tools on my phablet..(another day!) Can you tell me what is the best Windows-based solution as well please, -to compare?

All the r.basin.* series are sensitive to threshold size, so everywhere you specify a threshold value try increasing it -- greatly -- until you get a number that works for your needs.

I had initially thought I could use the Console window, but this appears not to accept Unix commands. The console window doesn't recognise any commands; it's the shell which is run in it which executes commands. If you use the Command Prompt entry in the start menu, you'll get a console window running cmd.exe (largely backward-compatible with DOS). MSys and Cygwin each offer a version of bash, along with some utilities. Cygwin provides a higher degree of Unix compatibility, but is more heavyweight. MSys and Cygwin each include a terminal emulator (rxvt for MSys, mintty for Cygwin), and the corresponding icon uses this terminal emulator to run bash. However, either version of bash can be run in a Windows console window if that is preferred. I also tried the included MySys Unix console which appears to be a Bash shell, but this does not recognise Grass commands. GRASS commands are designed to be run inside of a GRASS session. Essentially, this requires certain environment variables to be set (e.g. GISBASE must contain the path to the GRASS installation, GISRC must contain the path to a file containing certain settings, PATH must include the directories containing GRASS programs and DLLs). GRASS is supplied with a batch file which sets the various environment variables then starts a shell and/or a GUI. What would you recommend is the best option if I want to use Grass quite a lot, but don't want to convert my PC to a fully fledged Linux system (unless that really is the best option, such as using an emulator). GRASS 7 should run natively on Windows, i.e. it shouldn't require bash or any Unix utilities. GRASS 6.x requires bash and standard utilities in order to run various shell scripts (these have been converted to Python in GRASS 7). The Cygwin version should only be used if you particularly want a Unix environment but only have a Windows system. -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
