3D Cadastre System using the Node-Relation Structure in GIS

The foundation for the development of GIS throughout a local government is cadastral GIS applications. The applications need to maintain the cadastral data known as the tax assessment role, to evaluate land values including buildings and physical structures. Because the current 2D Cadastre systems with 3D visualizations (ArcScene) is a framework to support comprehensive land-related information such as land use, buildings, flood hazards, income and population at the parcel level, there are limitations in representing the complex internal structure of the buildings on geometric and thematic dimensions in the 3D entity (room units) level. It may create difficulty to understand and analyze the human behavior in micro-scale environments. This study, therefore, intends to propose a new approach in creating a 3D cadastre using a 3D topological data model based on Node-Relation Structure in order to represent the 3D attribute data integrated with the 3D spatial data (geometric and topological data) of 3D objects in 3D GIS.
