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
