Re: [Qgis-user] Linking tables in QGIS vector objects?
Agustin Lobo wrote: Hi! I have a vector map of land use, I'd like to know if the following operations can be made with QGIS: 1. Create a table with a list of the 7 Land use types that are present so that I can select one land use and get highlighted all polygons with that land use. 2. Link this table of 7 land use categories to another table of, for example, biomass/ha, so that I can display a map of biomass/ha. 3. Calculate the product of the biomass/ha * ha of each polygon and get it as a new variable in the original table for display. I konw I can do 2 and 3 in R and then bring the output to QGIS, but would like to know if there is a QGIS way for this, in particular the link between tables (through Postgis? I've no idea on how to use it) Thanks, Agus The short answer is that yes it's possible to do what you want using SQL. You can either take the approach using PostGIS or GRASS (I recommend SQLite backend) In grass 6.3 there is a v.db.join that would join data. My prefered way though is to use SQLite Manager(Firefox extension) to import the reclass table to the grass attribute db. Then do an update query populating a new column in the vector layer with the required information. You can also do simple mathematical operations like division. This is the same basic approach as with PostGIS. In fact the SQL statements would be almost identical. Basic steps - Load vector layer, and corresponding text layers; do some SQL; map output based on updated attribute table. Alternately, I think most of the steps might be possible now with a combo of plugins primarily from Carson, add this to your plugin manager and take a look at Join Attributes http://www.geog.uvic.ca/spar/carson/cfarmerQgisRepo.xml Alex ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

I have noticed a quite similar problem in QGIS 0.10 @ Ubuntu 8.04. The new Installer doesn't see installed plugins, because the QgsApplication.qgisSettingsDirPath() method returns the QTextCodec object instead of QString. It's really suprising for me. Ubuntu 8.04 - QGIS 0.10 - python-qt4 4.4.2.0 - python-sip4 4.7.6.0 (all packages from ppa.launchpad.net) - python 2.5.2-2 - KDE 4.1 latest beta Regards, B. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Cannot open DEM
Thank you, Jeff, Marco, and Aaron —
I have tried using Grass plugin, but even grass complain that the file
"Does not appear to be a USGS DEM file". So, looks like Aaron is right,
TNRIS messes up the file format. However, I am gradually going through
one of the DEMs byte-by-byte and have not found anything wrong so far
(up to byte 900). Unfortunately, GeoComm site is not an option because
it's not free, though thanks for the link, Jeff, I'll use it for my
personal projects.
I am trying to get XYZ data for the area, so, hopefully, I'll have the
DEM.
That's the story so far,
Mikhail.

Re: [Qgis-user] qgis0.10_lenny
Hi,
it looks like something really strange is happening in your case: the
errors are related to conversion between Python and Qt types. Thus I
suspect your installation might contain some incompatible pieces or
something like that.
- have you installed qgis from a package or from source?
- did you have some previous version of qgis installed?
- is this happening from the time you've installed qgis or it might be
caused by some upgrade?
- what versions of packages python, python-qt4, python-sip4 do you
have installed?
