3.4.1
Each LSG must derive its Street Name and Address Change Intelligence from official SNN Authority processes.
3.4.2
Other Address Change Intelligence should be introduced from other local authority statutory functions that affect Streets within the gazetteer. Some examples of these functions are:
- Building Control.
- Development Control.
- Highway Management and Maintenance.
- Land Charges.
3.4.3
Street naming functions, planning development control and building control are not statutory duties of all LHAs.
3.4.4
In a ‘two-tier’ structure of County and District or Borough Councils, these functions are the responsibility of the ‘lower-tier’ authority.
3.4.5
In these circumstances, all parties involved should establish effective relationships between organisations and find a way to transfer of change intelligence electronically.
3.4.6
For a diagram indicating the data flows associated with this process, see Appendix F.
3.4.7
Except for the entry date, as a minimum, if a Street is recorded in both the LSG and the LLPG, then the populated attributes which are associated with that Street must be identical in both gazetteers.
3.4.8
The exception to Section 3.4.7 is the entry date. This Field must show the true entry date of the Street in each gazetteer, therefore can be different depending on the information exchange process which is in place.
3.4.9
The locality and town data contained in the LSG (descriptive identifier) must not be based on postal localities and post towns as defined by Royal Mail. Geographic identifiers should be used.
3.4.10
These identifiers can help with the identification of the geographic location of the Street through a series of geographic instructions or real-world locations in common use.
3.4.11
However, frequently the adopted postal geography is the same as the derived real-world geography.
3.4.12
A County or Unitary Council must have a designated Authority Street Custodian who has sole responsibility for the maintenance and content of the LSG and ASD.
3.4.13
This ensures that a single source controls the addition, archiving and changing of all ESUs and Street Data in the LSG.
3.4.14
A consistent approach can then be adopted for all entries in the LSG and ASD within the LSG administrative area.
