Demonstrators
The demonstrators are a series of examples of how DNF enables relationships to be generated and reused between spatial data from different sources. Each example is a practical, hands-on demonstration of the underlying principles of DNF.
Read more about the demonstrators at www.dnfdemo.org. Note that new users will need to register (registration is separate from the DNF website itself).
Example 1 - General Concepts
Example 1 - General Concepts
Interest Group: General Concepts
This example demonstrates simple relationships between Buildings, Streets, Addresses and the Reference Base.

Example 2 - Address and Land Parcel Cross-Referencing
Example 2 - Address and Land Parcel Cross-Referencing
Interest Group: General Concepts
A demonstration of simple relationships between Land Parcels, Buildings, Streets, Addresses and the Reference Base.

Example 3 - River Attribution and Cross-referencing
Example 3 - River Attribution and Cross-referencing
Interest Group: Environmental
In this example, simple relationships between Water Features from different organisations, including the Enviroment Agency and their relationship with the Reference Base are demonstrated.

Example 4 - Fault Reporting
Example 4 - Fault Reporting
Interest Group: Service Delivery
This particular example demonstrates how DNF principles can be used in the context of creating, sending and relating fault reports on streets, street furniture or utility related household problems.
DNF principles can be used to validate data entry and to identify patterns and relationships in data after it has been recorded. The location of the fault reports, which are fundamental to the fault reports themselves, are recorded using the cross-referencing approach described by DNF.
Example 5 - Social Exclusion
Example 5 - Social Exclusion
Interest Group: Social Exclusion
DNF principles can be used in the context of cross referencing information to identify areas and groups of households that are not receiving the necessary services, but that might well benefit from them.
Datasets from different departments have been combined to enable accurate statistics about worklessness and social exclusion to be calculated and monitored. The data used in this demonstrator is not real, but has been produced to show how such information can cluster in particular neighbourhoods.

Example 6 - Flooding Emergency Response
Example 6 - Flooding Emergency Response
Interest Group: Emergency Services
This particular example demonstrates how DNF principles can be used in the context of sharing information between organisations to support planning for and emergency responses during serious flood events.
