[OpenLayers-Users] on line geocoding services

[Dr. Franz-Josef Behr]

If we talk about open / free services I'd like to point to 
http://www.opengeocoding.org.

In contrast to commercial solutions, this project (the result of a 
Master's thesis at our University) aims to implement a free, 
participatory, community oriented geocoding service. On the one hand, 
registered users can submit address information and corresponding 
coordinates. Special attention is given to their validation to prevent 
spamming by comparison to existing data on country, province, city and 
street level. Alternatively, users can use a Web map to digitize the 
location, supported by AJAX based techniques for map display and 
autocompletion. After successful validation, address and coordinates are 
saved into the database.

Based on this data, geocoding services for postal addresses is offered 
free of charge through a number of REST based web services providing 
results in XML, KML, GML, and JSON format.

The geocoding application does not rely only to its internal database 
filled by the community. If no relevant results can be gained from the 
internal database, the request will be forwarded to other publicly 
available geocoding services. The result will be checked, parsed, and 
forwarded to the user.

While commercial solutions concentrate on industrial countries, this 
service aims particularly offering geocoding for developing countries.

Up to now there are not so much locations in the DB as I expected. But I 
hope for further growth!


Mit freundlichen Grüßen / Regards / Cordialement
