I have created a small layer for the Layar augmented reality browser for mobile devices. It shows all known fietsknooppunten in Flanders.
I have implemented this layer as a Java application deployed on the Google App Engine. It consists of two parts.
- A daily cron job downloads a CSV database from Fietsnet (with permission) and stores all entries in the object store.
- A servlet responds to requests from the Layar application on the mobile device and returns a JSON response with relevant POIs.
