QGIS CKAN-Browser

QGIS PlugIn to load and display Open Data from CKAN enabled data portals.

Sponsored by Amt der Kärntner Landesregierung - KAGIS

Change log

DISCLAMER

It is very likely that data from some servers cannot be browsed or downloaded!

References for the time being are:

Pull requests that make such servers accessible (and don't break others) are welcome!
