❌Site Routing Point
This feature type no longer contains any features or data. It is in an 'end of life' state, where it has stopped receiving updates. If you have an existing OS Select+Build recipe that uses this feature type or transact with it via an OS NGD API, no records will be returned for it and you will receive a blank file.
You can access historic data for Site Routing Point using the temporal filter option in OS Select+Build by selecting the tick box for a 'one-off snapshot'; historic data is available for this feature type from 03 October 2022 to 25 April 2023.
As part of a data enhancement programme in late Spring 2023, all Site Routing Point features were recreated as Road Nodes and they are therefore now accessible via the OS NGD Transport Theme (from the OS NGD Transport Network Collection).
The location on the road network which provides entry or exit into a site for vehicles and / or pedestrians, represented as a point geometry.

Loading OS NGD CSV files into databases
Comma-separated values (CSV) file format is universally supported for easy ingestion into all major database products. Before loading OS NGD data contained in CSV files into a database, it is necessary to create relevant tables. Data definition language (DDL) statements for PostgreSQL, SQL Server and Oracle can be accessed in our OS NGD Resources GitHub repository.
For instructions on loading CSV files, see the Getting Started with CSV guide.
