Re: [Qgis-user] qgis/postgis : flow map

To understand you correct: In your raw-data table entrants you have one row for each person and in your query you want one flow for each person, ie. the same number of rows in your output? In the regards to the group by, you want the sum(ipondi) on each flow where they're grouped by a

I think you undervalue what's been done. See the code base, and re-use/adapt whatever components you want. You can run your own custom version. https://github.com/fieldpapers Could even integrate it with QGIS as a plugin, or flip that around and use QGIS server to create the tile layer used in

Thanx guys for the hint, but this is a "serious" project ;) My detail maps I have to produce are scattered around an area of ca. 200 sqkm, I want to have the freedom to design everything I want to with overview maps for finding the spot, inserting already existing data etc. So

Let me echo Brent Fraser suggestion to look at Field Papers, fieldpaper.org. They accomplish what you are looking for. Each page of the field paper has a QR code for georeferencing. Not only that they can be loaded in as a baselayer in OSM editors. The site fieldpapers.org has a simple walk

Try use DB Manager (QGIS Plugin - Comes with standard installation of QGIS), here you can connect to the database and run queries and afterwards import the queries into QGIS. When you've create a link to your database in "Add PostGIS-layers" (Ctrl + Shift + D) it should show up in DB manager
