Each of the relationships provided have their own unique use cases depending on the features that are being related to each other. The following section provides suggested use cases for each relationship.
Relating the RoadLink feature to a TopographicArea enables the visualisation of data collected and linked to RoadLinks (pollution counts, accidents, traffic speed) and visualises it by colour coding the relevant road surface area. Additionally, it can be useful for analysis enabling the road surface area to be calculated for a given road section.
Having links between Road with TopographicArea allows for the full extent of the road to be joined to all the TopographicArea features that represent it. This can be useful to calculate the full surface area for that named road and for displaying data linked to the road name by colour coding the road surface area.
Being able to relate a Street USRN to a TopographicArea TOID is useful for calculating the total road surface area for a given USRN. It can also be useful to display data related to the USRN such as maintenance history and schedule.
Having a link from the BLPU UPRN to a TopographicArea TOID is useful for calculating the area of the building footprint related to an address. It can also be useful to colour code building TopographicAreas for displaying related data for that address, such as council tax band.
Being able to relate each section of road to its road name is very useful for validation and can also be useful for aggregating data collected at the RoadLink level for sharing at the Road name level.
The RoadLink TOID to Street USRN is useful for aggregating data collected at a RoadLink level to a USRN for reporting. It is also useful for validating that the USRN is the one you are expecting.
Knowing which RoadLink accesses a property UPRN is useful during conveyancing to determine if the road is private or not, and if it is carrying any maintenance liabilities. It is also useful to be able to relate
a RoadLink to all the property UPRNs accessed by it in case you need to notify them about upcoming roadworks.
The primary use case for relating a Road TOID to Street USRN is to validate that the USRN you have is related to the road name you’re expecting. It’s also useful for identifying where a single named road is
maintained by two different administration areas.
Roadworks are often scheduled using the USRN. Being able to relate a USRN to easily identify the UPRN addresses that are accessed by the road, is useful to aid notifying residents of possible upcoming disruption.
These two tables have a very specific use case which is to enable data that is published against an OS MasterMap Highways RoadLink TOID (such as pollution counts, traffic accidents or average vehicle speed )to be visualised with the OS Open Roads product. This enables public data to be visualised for free.
