Future Trends for Modern DCDB's, a new vision for an existing Infrastructure
A legal cadastral model allows for a seamless three dimensional description of interests in the cadastre. The delineating of these interests is achieved through definitions within the relevant acts, dimensions and notations on registered documents and the position of real-world features.
Our current digital cadastral databases were originally designed to emulate and replace the traditional paper based working maps. This usually models the cadastre as a series of flat layers. For example layers of cadastre for base cadastre, strata, secondary interests and administrative boundaries.
As cadastral interests become more geometrically complex and the requirement for information integration increase a new model of the digital cadastral database is required.
