“…A RichWPS orchestration engine in combination with a DSL (Domain Specific Language) is used to orchestrate WPS processes and publish the composition as a WPS process for further composition [32]. In addition, there are many popular workflow management systems to facilitate the integration of geoprocessing services, such as Taverna [33,34], Triana [35], Kepler [36], jABC [9,37]. However, they only simplify the workflow construction process at the syntactical level, and building a workflow composed of services for geospatial problem-solving is still challenging for end-users.…”

In recent years, the rapid development of cloud computing and web technologies has led to a significant advancement to chain geospatial information services (GI services) in order to solve complex geospatial problems. However, the construction of a problem-solving workflow requires considerable expertise for end-users. Currently, few studies design a knowledge base to capture and share geospatial problem-solving knowledge. This paper abstracts a geospatial problem as a task that can be further decomposed into multiple subtasks. The task distinguishes three distinct granularities: Geooperator, Atomic Task, and Composite Task. A task model is presented to define the outline of problem solution at a conceptual level that closely reflects the processes for problem-solving. A task-oriented knowledge base that leverages an ontology-based approach is built to capture and share task knowledge. This knowledge base provides the potential for reusing task knowledge when faced with a similar problem. Conclusively, the details of implementation are described through using a meteorological early-warning analysis as an example.
