Abstract. This paper presents a methodology for a low – cost 3D visualization of property rights in multi – storey urban buildings using available and other relevant open geometric and legal data. An online, free platform is created, named “CadaSPACE”, to support the homogenous visualization of volumetric property units and open property rights included in 2D cadaster. The platform is directly interconnected with open – access pages such as the National Cadastral Portal, Autodesk Online Viewer, Tandem, Google Earth and Online 3D Viewer. It offers a wide range of statistical tools such as tables and diagrams to present, filter and manage the sematic information of the 3D property volumes. An application is presented for the Greek Cadaster. Legal information about the property rights is collected from the open - access cadastral records; building footprints are digitized on the available Orthophotos; architectural floor plans of each individual property unit are either taken from the documents included in the electronic building identity records (under construction) or are provided by the owners, and an approximate BIM (Building Information Model) is created for each building using additional approximate geometric information derived from Google Earth Pro and Streetview. The 3D property units are modelled and visualized as volumes. The whole 3D neighborhood model is uploaded online for further categorization and management through various visual and semantic filters. Considerations for further legal and technical improvements are given towards the implementation of the proposed methodology.
