- KonferenzbeitragAus Groß mach Klein: Verarbeitung orchestrierter OGC Web Services mit RichWPS Server- und Client-Komponenten(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Wössner, Roman; Abecker, Andreas; Bensmann, Felix; Alcacer-Labrador, Dorian; Roosmann, RainerRichWPS is a project aiming at more powerful and more user-friendly support for using the OGC Web Processing Services standard (WPS) for distributed geodata processing in the Web. While we have already discussed in other publications the RichWPS ModelBuilder for geoprocessing-workflow composition as well as the RichWPS approach to geoprocessing-workflow orchestration, this paper sketches the RichWPS Server software as well as some client-side developments facilitating the effective usage of WPS processes.
- KonferenzbeitragAus Klein mach Groß: Komposition von OGC Web Services mit dem RichWPS ModelBuilder(Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Bensmann, Felix; Roosmann, Rainer; Kohlus, JörnDistributed geospatial data and services can be used to form Spatial Data Infra-structures (SDI). Current technological developments enable SDI to process large amounts of geospatial data. In this context, Web Processing Services (WPS) can be used as an open interface standard for accessing and executing geospatial processes. Since many SDI are based on Service-Oriented Architectures (SOA), the orchestration of services is enabled by composing existing services. The results are higher services, e.g. complex geospatial applications. The RichWPS research project focuses on analysing and providing practical approaches of web service orchestration. For this, software components are developed to build a modular orchestration environment. The main client-side application is the ModelBuilder.
- KonferenzbeitragGeographic Information Systems Support for Monitoring Environmental Impacts Caused by Deep Hard Coal Mining(The Information Society and Enlargement of the European Union, 2003) Roosmann, Rainer; Busch, Wolfgang; Gorczyk, Julita; Mauersberger, Frank; Nickel, Stefan; Vosen, PeterEvery human activity has impacts on the natural environment, also deep hard coal mining with long-lasting activities and digging huge amounts of hard coal. To detect and minimize effects on anthropological landscape and natural environment, monitoring of specified phenomena takes place. This means large amounts of data and complex analyses that can’t be accomplished without using computerised support, especially by GIS. So this paper provides an insight into the concept of monitoring environmental impacts and how GIS can be used to support this.

- KonferenzbeitragMethods and Tools for More Efficient Working With OGC Web Processing Services(EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Abecker, Andreas; Wössner, Roman; Alcacer-Labrador, Dorian; Bensmann, Felix; Roosmann, RainerWe start with the observation that the OGC Web Processing Service (WPS) is by far less widespread in public administrations than the OGC download and visualization services WMS, WFS, WCS. Based on this observation, it was the goal of the RichWPS research project to develop methods and tool which should facilitate the use of WPS in practice. Now, after the end of the RichWPS project, we briefly review most of its methodological and technological outcomes and try to conclude to which extent the project goals have been achieved.
- KonferenzbeitragOrchestration of Geospatial Processes with RichWPS – a Practical Demonstration(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Ziegenhagen, Dennis; Kohlus, Jörn; Roosmann, RainerDistributed geospatial data and services can be used to form Spatial Data Infrastructures (SDI). Current technological developments enable SDI to process large amounts of geospatial data. In this context, Web Processing Services (WPS) can be used as an open interface standard for accessing and executing geospatial processes. Since many SDI are based on Service-Oriented Architectures (SOA), the orchestration of services is enabled by composing existing services. The results are higher services, e.g. complex geospatial applications. The RichWPS research project focuses on analysing and providing practical approaches of web service orchestration. For this, software components are developed to build a modular orchestration environment. Real-life examples of geospatial processing are analysed and divided into simpler, reusable sub-processes. Using the RichWPS environment, the sub-processes are implemented and arranged as workflow models, which are deployed to an extended WPS server and interpreted by its orchestration engine. This enables workflows to be executed by WPS clients. This paper presents the RichWPS environment and one of the analysed real-life scenarios. The example scenario “Macrophyte Assessment” contains the assessment of water plants in order to report on the water’s qualitative status. This meets requirements of the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD) of the European Union. The scenario is analysed in order to identify elementary processes. With the use of RichWPS components these processes are orchestrated to form an executable assessment procedure.
