[Qgis-user] OpenStreetMap import

[Mayeul Kauffmann]

Hi,
There is virtually an unlimited number of key=value pairs in OSM.
Partly because key and values are absolutely free; partly because even
mappers who try to follow guidelines make typing errors.
You will need hundreds of columns to create columns for each key. 
The best solution I am aware of is to filter features (in QGIS) based on
a full text representation of the tags.
You can get this:

I have developed a tool to prepare the data for use in QGIS, see:
http://wiki.openstreetmap.org/wiki/Osm2postgresql

I also created tools to make a statistical analysis of the frequency of
tags, and used this to fine tune my styles. FOr a demo, see:
