Is your feature request related to a problem? Please describe.
There's no info about offices/lecture halls/labs etc in our campus.

Describe the solution you'd like
Gather all data with images and locations and add them to NavigaTUM.

Currently we get our data from patches and other roomfinders.
=> see https://nav.tum.de/about/about-us for a list of our sources

Is there a Roomfinder/other publicly scrapable source for the Heilbronn campus we can access?
(As I am not located there and TUM does not cover travel-expenses for my position, going there and looking is not feasible)

I think for the scale of the Heilbronn campus (and the low amount of different lecture halls):
Is a roofinder even helpfull?
