Thank you for this map! Two questions: - what implementation of quadtree are you using? - will you ever consider opening the data for download as shapefiles/any other vector format? Thanks again, great job!

My own quad tree, they're not that hard to write :)

We're not considering opening the data. But we are working with cities to help improve their bike infrastructure
