Mixed gazetteers
6.3.5.1 Conventions - mixed gazetteers
LSGs must be created and maintained to level 3. All DCA Street Update transfer files to GeoPlace must be at level 3. However, because of the latency of survey of base mapping material, a level 3 gazetteer has some level 1 or 2 Streets. In this case the Authority Street Custodian must do one of the following things:
- Leave the Street at level 1 or 2 until such time a base mapping is available.
- Digitise the approximate location of the Street in the real world using reference material, for example developers’ plans.
