Geospatial web services can be enhanced with semantic web service techniques in order to solve the existing interoperability issues in the geospatial domain. Therefore a large number of services can be composed to provide meaningful results to complex geospatial queries, but as the complexity grows, the users face serious performance problems. On top of existing geospatial web services we adopt the WSMO/L/X framework which provides a model to define machine and human‐understandable semantic descriptions, full support for mediation and a simple language to choreograph the execution of a composition of several geospatial web services. Our research focus is on the semantic execution and its performance inside the WSMX platform. Our core contributions are: (1) providing a solution for automated semantic execution of geospatial queries; and (2) providing a combination of techniques and improvements to the efficiency aspect.
