OFC there are, and all the answer you will get if you report a bug is or It will be corrected in the next version (If you are willing to buy it). I'm not complaining. I have successfully Evangelize some people about using Quantum GIS to solve their GIS problems (instead of proprietary softwares). But this time it was not possible, the trainee needed to move on and try to do it in another software. I already post some test data in the issues. Thanks!

Re: [Qgis-user] Data capture in QGIS with offline PostGIS
Nathan, I've been thinking about something similar, using XAMPP. Would need to add in POSTGIS, Mapserver (and/or the new QGIS Server) and QGIS. I'm interested in setting up a package like this for the same sort of things, data collection in the field. I've been working with PostGIS for the last couple of months, and find it very sable, and have discovered some interesting capabilities during my configuration related to syncing databases, etc. Problem id, I don't have any one customer pleading for the this capability at the moment. So I would need to steal away time to develop a proof of concept. Do you have any possible funding for something like this? bobb Nathan Woodrow madman...@gmail.com wrote: Hi all, I'm currently looking at building a data collection program based on QGIS.

Re: [Qgis-user] Data capture in QGIS with offline PostGIS
Ivan, I was wondering about the concurrent editing as well. I also wondered if it might not be possble to combine data via something external to POSTGIS, like a Mapserver mapfile, instead of (only) relying on the POSTGIS merging capabilities. You could for example have a table per collector ID and then combine them for business needs and presentation. I guess it depends somewhat on the buisness specifics. bobb Ivan Mincik ivan.min...@gmail.com wrote: Does anyone know of anything I can use with PostGIS?

Re: [Qgis-user] QGIS 1.7.4
I had problems with joins with non-spatial data and the not too userfriendly vector opertaions, and this mainly with students. Our solution so far: we use spatialite as backend for students (postgis isn't that easy when lots of external data needs to be joined). It works great: - The initial spatialite db was created using ogr2ogr from our postgis server. - joining data is done in spatialite, with the spatialite-gui tool - new x,y data is created in spatialite too, just link to a file, use the makepoint function, done - spatial operations are performed in spatialite (some tricks needed, once you know, works great) QGIS is used for visualisation and some basic operations. The combination of both products works well for us.

[Qgis-user] pyspatialite problems in qgis 1.7.4-3?
I recently updated qgis to 1.7.4-3 by using the osgeo4w advanced installation and now there seems to be something wrong with pyspatialite. I get error messages from all the plugins QspatiaLite, SpatiaLite Manager and DB Manager. And none of the following attempts to import at the python console is working: *from pyspatialite import dbapi2 as sqlite* *from pyspatialite._spatialite import ** Strange thing is that I did include the pyspatialite package (2.3.1-2) and all the plugins (including importing pyspatialite at python console) are working fine in qgis-dev (f3b78ef).

[Qgis-user] Re: Collecting Events
Thanks for the replies. I came up with a slightly roundabout way of doing this. First, I buffered my points. Next I ran points in polygons to get a point count with the buffers. Finally, I ran polygon centroids to get a points feature class with the counts that I could represent as proportional symbols that show number of crimes per address. -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Collecting-Events-tp4633998p4637441.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] compiling QGIS version1.9.90-Alpha with GRASS 7.0
Hi, I have compiled QIGS 1.9 successfully when building with GRASS 6.4 (on Ubuntu 11.10). However, when I try to build it with GRASS 7.0, I am running into problems. In ccmake, I include the following when building with GRASS 6.4 (grass was build in usr/local/grass6.4.current): GRASS_INCLUDE_DIR /usr/local/grass6.4.current/grass-6.4.2svn/include GRASS_PREFIX /usr/local/grass6.4.current/grass-6.4.2svn LIB_PATH in /usr/local/grass6.4.current/grass-6.4.2svn/lib/libgrass_gproj.so GRASS 7.0 is build in usr/local/grass7.current, thus used the following in the ccmake: GRASS_INCLUDE_DIR /usr/local/grass7.current/grass-7.0.svn/include GRASS_PREFIX /usr/local/grass7.current/grass-7.0.svn LIB_PATH /usr/local/grass7.current/grass-7.0.svn/lib However, when running configure, it apparently cannot find the lib_path, even though I am sure the path is correct (the field for LIB_PATH is put to LIB_PATH_NOT_FOUND). I can still continue with make and make install and QGIS installs and runs fine, but without GRASS toolbox. Any help would be appreciated.

[Qgis-user] Digitizing Idea...
Hi Not sure if this has already been done or thought of... probably While clicking over a very winding river today to digitize an old map I was thinking it would be really useful to combine some graphic package features found in gimp/photoshop. The idea being that as you click it would preferentially follow a certain line/colour. I could thus select a colour on the map and then just click a rough path over the river with the software recognizing my intention and adjusting the path the best fit the line based on the colour I chose or follow the line.
