As an on-the-ground mapper in OpenStreetMap, I personally prioritize the local city transit network. It’s an economic powerhouse, and generally important public infrastructure as an alternative to driving. While mapping out transit nodes such as bus stops, I find it difficult to keep track of my progress. I wrote this program as a personal tool, but recognizing its potential, I’ve decided to publish it an expand its capabilities. It cross references two CSV files, one provided by a city of all known bus stops, and one that contains all bus stops that exist in OpenStreetMap, and produces an SVG file, illustrating how well mapped out the city is.
