    More and more countries in the world are developing 3D Cadastre. To make cadastral information available to the potential users, both cadastral sector professionals and normal citizens, the Web can be used as dissemination platform. However, visualization of 3D cadastral information is still a challenge.
    Some of the main issues are: occlusion, distortion, unbounded volumes, perception of position, size and shape of an object. For orientation purposes, it is important to include reference objects to help us understand the location of the parcels in the real world. Although, the resulting higher number of objects makes the clear visualization even more challenging.
    We therefore first investigate the requirements to obtain a proper, clear and not misleading visualisation of 3D cadastral parcels through a geo-web viewer. We explore how to handle the above-mentioned issues such as occlusion, distortion and ambiguous perception (in terms of position, size and shape) of objects while interacting with 3D cadastre. Also, techniques for combining the visualization of legal boundaries (cadastral parcels) and real-world objects (topography) are analysed.
    The overall technical architecture of a system for the dissemination 3D Cadastral parcels is presented, starting with the storage of the data at the backend server (DBMS and webserver) and the possible encodings for data transfer (such as XML, JSON, glTF) to the client. WebGL based solutions at client side are preferred as these do not require the download of a plugin in the web browser, while still offering many well performing visualization and interaction options.
