52-North is an open source software initiative that provides
implementations for many OGC standards. The entire framework is
written in Java and the WPS component supports raw data, HTTP,
SOAP and WSDL. It provides links to ArcGIS and GRASS-GIS functionalities
while R scripts can be exposed as WPS processes through
WPS4R. INTAMAP is one of the first experimental examples of web
services based on the OGC WPS standard. It is built on 52-North
WPS and provides functionality to exchange data, undertake statistical
analysis, automatically visualise results and communicate
uncertainty via UncertML (Cornford, 2009).
