"Good luck with that": Tag Teaming Civic Data
summary
A Ruby on Rails capstone claims a usable street-parking product built in four weeks by pairing; actual work uses the city ArcGIS map server, KML/ping overlays, shapefiles parsed via Python, and a rails API that caches requests with CarrierWave to S3 and background jobs. Surprises: projection mismatch solved by a wrong-but-working spatial reference id, public open-data stale since 2011, and a scraping strategy that may need 2–300 queries per citywide refresh. Result: a minimal viable mobile web/ iOS app that users already find helpful.
