3D Mapping to Collect Volunteered Geographic Information

This paper discusses the concept of crowdsourcing in combination with our new developed 3D viewer which is integrated in the technical infrastructure of PUBinPLAN, our digital participation platform. The voluntarily gathered information is collected on PUBinPLAN, where people can join and share their spatial knowledge on our 3D models of the city of Deggendorf and the Deggendorf Institute of Technology. Firstly, the technical details of the 3D viewer and the implementation into the PUBinPLAN website are explained and then, in a case study, the performance on different devices and in different browsers is analysed to ensure a smooth mapping experience for architectural approaches. This creates an added value to participatory regional and spatial planning processes.
