Throughout the course we will consistently use open data provided by the federal state of North Rhine-Westphalia via Geobasis NRW.
The following sites are the main starting points for the open data. Unfortunately there is only a German version provided. Please use Google Chrome (or another capable browser) to translate the pages to English!
To fill in all WMS, WCS and WFS services in the QGIS online resources go to link 3 and scroll down to the end to the table “Further Information”.
Right click on the links to the xml-files listing the online geodata services and save them locally on your computer's file system.
In QGIS click on “add WMS/WMTS layer”, “add WCS layer” and “add WFS layer”, respectively and load the corresponding xml files.
This provides a long list of all available online services by Geobasis NRW. Now you can connect to them and load them for your project.
