An Inefficient Model for National Spatial Data Delivery
This model provides an extremely powerful mechanism for coordination and assembly of fundamental national datasets The model focuses on the The model focuses on the removal of duplication through the establishment and management of a strong relationships network. relationships network. The model is sustainable as it delivers the value required by the market and the need for revenue ensures this focus

Address Complexity
- Address is derived from human language
– Influenced by human psychology
- reasoning, intuition and perception
- context specific
- Place is important in human cognition and
- Place is important in human cognition and
communication – Consequently, a high priority for human computer interaction – Forces consideration of conceptual modelling.

Address Complexity
- Address is a dynamic concept
– Rate of change is very high as there are many components that make up an address components that make up an address
- Address is not easily discoverable
– Complex sites lead to confusion and – Complex sites lead to confusion and inconsistency – Leads to individuals ‘constructing’ address with – Leads to individuals ‘constructing’ address with the knowledge that is available – Creates ‘alternate’ and ‘alias’ addresses that are used but not official or not accurate are used but not official or not accurate
