What OS Water Network provides you with
Named waterways
Rapidly identify the full extent of a named drain, canal or river using link sets comprising water links which make up a common named waterway.
Water network mapping
Filter, select, and refine the required data using attributes such as description and catchment name, and keep water network data up to date and accurate with quarterly updates.
Use cases
- Assess the environmental impact of water networks. Conduct ecology studies, including species migration, monitor the likelihood of water movement and upstream pollution, or identify the effects of natural disasters.
- Significantly enhance the systems used to manage waterways and rivers. Manage statutory directives relating to watercourses, and access a rich data attribution assigned to water movement that can predict and model flooding.
- Optimise flooding predictive models, to manage waterways and rivers, and establish appropriate flood protection and response measures.
Additional information
This data is generated from the National Geographic Database
The National Geographic Database (NGD) sets the benchmark in accuracy and completeness for location data. NGD data helps businesses and government make critical decisions, and deliver vital services with the utmost confidence and certainty.
The NGD is the single store of Ordnance Survey’s authoritative data for Great Britain; the repository of millions of records that precisely define the built and natural environment, in unparalleled detail.
Central to the power of NGD data is a single, structured database. Unlike previous generations of OS data, NGD data is built for analytical uses and designed to be the bedrock of more intelligent solutions. It reduces the complexity towards insight and getting the answers you need.
