I created two maps with umap for local politics in my city.

One is about cycling infrastructure: the status of a city council resolution that introduces city-wide safe cycling routes. The project is hardly going anywhere so this (and a blog) is me trying to get public pressure on: www.radmonitor-regensburg.de/hauptrouten. It includes different layers (standard is current status). Still needs some improvement in communicating the project and its message.

The second one is about maxspeed withing the city limit. There is a lot of discussion about slower car traffic in Germany. I got the existing OSM data with Overpass Turbo, exported the different speed limits and imported them to seperate layers in umap: www.radmonitor-regensburg.de/tempo30. Had to add some more data but overall I was surprised to see how well maxspeed was already documented (some data still missing but hardly anything, really).

The second project really got me started with Overpass, I use it regularly now to spot missing data and add it to OSM.

It is really great to see all the possibilities you have with OSM data and the tools around it!
