52°North WPS

The 52°North Web Processing Service enables the deployment of geo-processes on the web in a standardized way. It features a pluggable architecture for processes and data encodings. The implementation is based on the current OpenGIS specification: 05-007r7 .

Its focus was the creation of an extensible framework to provide algorithms for generalization on the web.
