Alex Mandel wrote: I'm a little lost here, in my experience a vector layer becomes a table, not multiple tables and all the geometries are stored in a blob column no matter what type it is. That's what I'm curious about. Each vector is becoming a table unto itself. That's not proper normal form for a relational database. Of course if you have multiple vector types in the same table this can cause issues with various spatial operations, so you either need to separate them out or subquery when you want to perform spatial operations to make sure you only use compatible types. Yes, this is exactly what you want when using a relational database in the proper manner. What tool did you use to import the layer into POSTGIS?

Re: [Qgis-user] Linking an external attribute table..
I accomplish this by using the Grass plugin and the sqlite driver for data storage. 1. Create a Grass Mapset 2. Change the driver to sqlite db.connect (I think) 3. Import the Vector layer to Grass 4. Now you can import any other attribute tables you want into your sqlite database, I use the Firefox SQLite Manager plugin to do this. Then I run queries to build tables I want to use with my layer or add columns to the attribute table. 5. Using the Grass plugin you can change what table is linked to the layer at any time or if you added columns to the attribute table the data will show up. Kinda round-about way, but it works.

Re: [Qgis-user] Relational Databases and PostGIS formatting of Vector Data
Yes, that is correct. Are there any other 'shp ingesters' for use with QGIS? AFAIK the PostGIS manager plugin is also able to load shapefiles into PostGIS, and this is a nice simple way to manage your database directly from within QGIS. I am thinking that my complaint regarding proper normal form for vector data ingested into postgresql should also be tempered with the idea that any database user could reorganize the ingested data into any format they desire. Therefore, it's not as though anything is actually irreparably disorganized or broken. Technically one could just add a trigger to the system catalogs to check if a new table has been added to the database and then go from there. Yes, I think you're probably right here. It would be difficult to create a tool that would import data into pgsql the way that everyone or anyone would like... so KISS is the best solution (keep it simple s...) from here it's up to the database maintainer to keep things the way they want it... Th postgis user lists would probably benefit from this discussion, have you suggested similar things there? Most of us on the QGIS lists aren't database experts, so a better discussion would probably come out of the postgis lists. Carson -- Carson J. Q.

[Qgis-user] WFS/WMS layers behind HTTP/HTTPS basic auth
Hello, I am wondering if there is a way to get QGIS to request the basic auth user name and password for WMS/WFS URLs that are protected by HTTP basic auth. When I put a URL (that uses basic auth) into the WMS server connections I just get an error that the return message is misunderstood when QGIS attempts to connect. Is there any way to use HTTP basic auth with QGIS WMS? Thanks Peter ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
