cadastral data model

The LPI Cadastral Data Model has been designed to support the LPI's cadastral data maintenance requirements.

The model represents current cadastral status but not necessarily current title.

The model has been developed using UML methodologies based on a target ESRI Geodatabase implementation and therefore certain aspects of the design reflect the requirements of that technology. The published design is a physical model and contains components required to support ongoing data maintenance activity. Cadastral data delivery and distribution systems will be based on this model, essentially containing all the entities and relationships described here with minor modifications to eliminate maintenance specific data elements, to model history and to optimise the structures for query, analysis and extraction
