Abstract
Building and Implementing a 4D Cadastral Information System
Track: High Accuracy GIS
Authors: Stacey Lyle, Jon Gustafson
The research contained within the confines of this paper focuses on the development of a cadastral information system where the user will be able to navigate through a cadastre at various levels of detail and view the parcels in a four-dimensional (4D) context. The traditional two-dimensional cadastre is valuable, but does not have the versatility to accommodate three-dimensional (3D) analysis as well as integrate the parcels history (from a land rights and geomorphic perspective). This paper evaluates the value, documents the processes, and analyzes the practical future of a 4D cadastral information system. This was accomplished by researching the necessary literature, selecting a viable parcel dataset, harvesting the necessary cadastral data, compiling the required geospatial datasets, developing the cadastre, and exploring implementation schemes. Using a combination of software applications, the resultant 4D cadastral information system yielded a 3D parcel model with simulated historical versions and comprehensive attribute information. Going forward, the promulgation of this type of a cadastre on a city (or larger) scale will require significant investment during all stages of implementation, but the largest impact will be the versatility of the 4D cadastral information system.
