Kemtro in the making

Video shows:

• The generated custom OSM map tiles, with the metro station, their names, and the station entrances.
• The route finding algorithm in action.

Custom map tiles

I created a suite of scripts and web interfaces to be able to enter the custom data were were using for the application, namely the metro stations and their entrances. We were also dropping or adding details depending on the zoom level. The goal was to have sufficient details depending on the zoom level, and have an overall limited size of the map tiles DB for download. Generating the map tiles required a lot of fine tuning to place the labels, and the details in the best way possible.
