"In the department of Surveying and Geoinformation (VGI) I deal with topics of future urban development, surveying and the creation of project-related GIS applications. The up-to-dateness of the natural inventory data of the entire urban area of Linz - both in 2D and 3D - forms an essential technical planning basis. The WebGIS - the internal GIS of the City of Linz - is a web application that makes a large part of the centrally stored geodata available in high quality to all authorised users on the intranet. Individual and simple workflows enable even non-technical departments to enter their own geodata."
