Geospatial Web Services for Distributed Processing: Applications and Scenarios

Processing and modeling of geodata are essential parts of the daily work of GIS technology experts. Domain experts often need to perform sophisticated GIS analysis of complex data. Currently, capturing, storing and requesting data are embedded in Spatial Data Infrastructures using Service-Oriented Architectures. GIS analysis is performed locally by first downloading geodata such as from SDIs. With the advancements in network bandwidth, processing power and the standardization of Web technology and Geospatial Web Services, distributed geoprocessing is the next step of realizing GIS analysis on the Web. Geoprocessing Services are considered to be a key aspect of meeting the requirements for distributed geoprocessing on the web. This chapter provides an overview of the current state-of-the-art approach of distributed geoprocessing by describing the related concepts, such as the OGC Web Processing Service, workflows, Quality of Service and legacy system integration. Furthermore, the chapter demonstrates different applications for distributed geoprocessing. Finally, this chapter examines the introduced concepts by two scenarios.
