description European mapping institutions recently started creating three-dimensional (3D) topographic datasets to satisfy modern application demands. The resulting datasize creates new challenges for managing, disseminating and visualising topographic surface models interactively. Moreover, open, publicly-available, free-of-charge software is desirable for data dissemination, so that the general public can access the public-funded survey results. Available large-scale visualisation platforms are commonly proprietary. In this paper, we contribute three major points that address the visualisation- and dissemination challenge: First, we present a scheme for extending open scientific visualisation platforms with out-of-core rendering capabilities. Secondly, we present a practical processing workflow for geometric corrections and storage of the surfaces for interactive visualisation. At last, we present a GML-based storage structure for large-scale data dissemination. First results show interactive rendering capabilities for a city dataset which was formerly impossible to render in its entirety. The developed processing workflow is versatile and handles polygonal inaccuracies with minimal input constraints.
