As geoprocessing on the web has matured in recent years, an increasing number of geoprocessing services and functionality are becoming available in the form of online Web Processing Services (WPS). Consequently, the quality of such geoprocessing services is of importance to ensure that WPS instances fulfill users’ expectations. In this paper, we illustrate, and discuss initial results from a quantitative analysis of the performance of WPS servers. To do so, we used two test scenarios to measure response time, response size, throughput, and failure rate of five WPS servers including 52 Degree North, Deegree, GeoServer, Py- WPS, and Zoo. We …

Agricultural land use in Germany and related impacts on the environment and the use of natural resources are key research topics at the Thünen-Institute of Rural Studies. As spatial context is essential for the analysis of causal connections, GIS data regarding all necessary information was gathered during different research projects and prepared for processing in a database. In particular, the Integrated Administration and Control System, which was available for certain project purposes for several Federal Laender and years, serves as a very detailed data source for agricultural land use. We use different Open Source GIS software like PostgreSQL/ PostGIS, GRASS …
