When we were at TU Graz for the KDE Plasma Sprint and Grazer Linuxtage a few weeks ago the question came up how to practically map such buildings in OpenStreetMap given their available floor plans. As I’m mostly involved in using rather than creating OSM data I didn’t have a good answer for that back then. Thanks to input during the following quarterly OSM Indoor Meetup, you’ll find some hints on approaches and tools below.
