Added 797 motorcycle parking bays to London OSM using council FOI requests
I've been sending Freedom of Information requests to London councils asking for their motorcycle parking bay data, then uploading the missing bays to OpenStreetMap.
So far: 240 from Camden (open data), 69 from Tower Hamlets (FOI), 313 from Lambeth (FOI), 171 from RBKC (FOI, with BNG coordinates converted via pyproj). Plus 4 from personal surveys. Total: 797 bays added.
The process: download council data, run a gap-finder script comparing council bays against Overpass, geocode any streets without GPS coordinates via Nominatim, spot-check 6 random bays on Google Maps, then upload via JOSM.
Spot-check accuracy has been 94-100% across all four boroughs. Council data is surprisingly reliable since they use it for enforcement.
The data powers a free motorcycle parking finder at parkmoto.london, but more importantly it's all on OSM for anyone to use.
Still waiting on FOI responses from Islington and Southwark. Happy to share the FOI template if anyone wants to try this approach for other data types.
