Abstract

This paper describes research into the visualization of mixed 2D and 3D Cadastre. A schema has been developed to accommodate this data, with provision for a time component. This paper describes the schema, the visualization requirements, and the provision of LADMcompatible views of the data for the purpose of developing these tools, and for the further research into the schema itself. A significant volume of 2D+t Cadastral data, which also contained 2D+t representations of 3D parcels, is currently incorporated in the Cadastral Database of Queensland. A moderate number of 3D building units, and a smaller number of volumetric parcels have been hand-encoded using bespoke software, and added to this database. The mixture has been displayed in KML through Google Earth. Examples of the database schemas, the encoding practices, LADM-compatible views, and the encoded 2 and 3 dimensional spatial units are included.
