Technological advances foster the role of web-based infrastructures for spatial data provision and analysis. Current challenges for online information generation include the timely integration of data from heterogeneous sources, the documentation of data provenance and analysis workflows as well as the automation of spatial analyses. The research group Geographic Information Infrastructure (GII) contributes to these research challenges and specifically works on the architectural specification and utilisation of semantics of spatial data and analysis functionality. Our key objective is to support users at their spatial analysis tasks and at the management of spatial data infrastructures.
