Planning inner-city-railway-tracks: Dynamic integration of geospatial web services in a collaborative multi-scale geometry modelling environment

Planning inner-city-railway-tracks is an interdisciplinary and highly complex task that involves plenty of different stakeholders. Currently, the different planners work more or less separated in an asynchronous manner. To facilitate a collaborative planning process between these different stakeholders we developed a collaboration platform. Clearly, the integration of geographical information and geoprocessing results into the planning process respectively the different modelling tools, improves this process in a significant way. In this paper, we will show how to describe the needed geographical information in a suitable way and how to integrate these pieces of information into the different planning tools via the collaboration platform in a unified, dynamic, and generic way.
