WPS Client udig Introduction

"The User-friendly Desktop Internet GIS (uDig) is both a GeoSpatial application and a platform through which developers can create new, derived applications. uDig is a core element in an internet aware Geographic Information System." (taken from the udig website)

Based on this description and the need to process distributed services on the Web we decided to develop a plug-in for uDig. The facilities of uDig allowed us to develop enhanced distributed web service based processing of geodata. Besides the client-based visual integration of processing results with other distributed sources (e.g. from WFS and WMS), the possibility to chain sources within a WPS for a distributed process was the main argument for choosing uDig.

The advantage over the existing JUMP client is first the pleasing visualization of features and its powerful styling capability but mainly the seamless integration into OGC Web Services (e.g. WFS and WMS).

To get a short idea of the integration of WPS and other services in udig using the developed plugin please take a look at the screeenshots below.
