OSM Housenumber Evaluation

Improving Address Quantity and Quality Through Automated Analyses


OpenStreetMap is set to cover more and more addresses. This talk demonstrates a tool designed to automatically detect missing house numbers, by comparing data from OSM with data retrieved from a city council or similar authority. The government data doesn't have to have a geo component - simple lists are sufficient.

This approach has been used with good results in various places in Germany, and also includes a method to generate feedback to the administration (whose data is often less than perfect).
