摘要：The CampusGIS of the University of Cologne (http://www.campusgis.de) is designed, developed and established by the GIS & Remote Sensing research group at the Department of Geography. It is a web-based application to provide and visualize general and spatial campus information, e. g. advanced search functions, orientation, routing, and facility management. Several existing relational database systems of the University of Cologne with spatial data were connected within that online GIS environment. The overall design approach is based on this database linkage with spatial data to provide location-based services (LBS) (Baaser et al. 2008). This paper presents the major recent networking improvements based on a topological validated line-network to provide online routing applications for pedestrians and comparable user groups. Therefore, several objects and attributes of the CampusGIS geodatabase were surveyed, digitized and joint to selected objects of the ATKIS-street dataset (ATKIS = Authoritative topographic cartographic information system of the Federal Republic of Germany).
