Description
The OpenStreetMap has tons of great data. But one big thing is missing: a good geocoder. In this rails rumble we implemented one. One that is supposed to be awesome and scaleable.
As the backend database we used the new NoSQL database ArangoDB (http://www.arangodb.org)!
We took the OpenStreetMap data and transposed it in a way that made more sense for geocoding. During the implementation we found some flaws and tried to adjust. Due to the pure amount of data, the lack of a scalable machine for transposing and the time we had to process the data, we reduced the dataset to North Rhine-Westphalia, Germany. This means you can search for addresses in Köln, Bochum, or even Düsseldorf.
Next to the Rails application that lies in the RailsRumble repository, we created an importer (happy-importer) gem that takes an OSM-XML export and transposes it into our format. We also created a parser (parsec) for German street addresses that disects the user input and normalizes the data to be searched. Both gems can be found at a seperate organization: https://github.com/happy-geocode/
If you are not familiar with German addresses, here are some sample queries for you:
Street & City: Christinenweg, Hamm
Street & Zip: Markfestestraße, 52457
Street, City & State: Bredeneyer Straße, Essen, NRW
Streets with unusual names:
- Scharpenberg, Mülheim an der Ruhr
- Dimbeck, Mülheim an der Ruhr
