Statutory Main Rivers Map is a spatial (polyline) dataset that defines statutory watercourses in England designated as Main Rivers by the Environment Agency.

Watercourses designated as ‘main river’ are generally the larger arterial watercourses. The Environment Agency has permissive powers, but not a duty, to carry out maintenance, improvement or construction work on designated main rivers.

All other open water courses in England are determined by statute as an ‘ordinary watercourse’. On these watercourses the Lead Local flood Authority or, if within an Internal Drainage District, the Internal Drainage Board have similar permissive powers to maintain and improve.

This dataset is wholly owned by the Royal Yachting Association (RYA). The Royal Yachting Association (RYA) UK Coastal Atlas of Recreational Boating is a GIS dataset of recreational boating activity around the UK, comprising spatial data including indicators of intensity of use, general boating areas, offshore routes, as well as the locations of clubs, training centres and marinas

Audience: PublicExtent: United KingdomYear: CurrentUpdate Frequency: Every Sunday Walk Wheel Cycle Trust (formerly Sustrans) is the custodian of the National Cycle Network (NCN). We work with our many partners and stakeholders to develop the Network across the UK. This view layer depicts more than 12,000 miles of signed paths and routes for walking, cycling, wheeling and exploring outdoors.While we receive updates from regional staff and volunteers on a continuous basis, we can't guarantee the data to be free of error. If you discover an error please inform us by emailing our Walk Wheel Cycle Trust GIS team so that it can be corrected. About Walk Wheel Cycle TrustWalk Wheel Cycle Trust is the charity making it easier for people to walk and cycle. Join us on our journey, Walk Wheel Cycle Trust Website Layer VisibilityThis layer contains over 35,000 polyline features. To optimise drawing performance the view layer has been limited to Cities (1:160000) level. Known IssuesThe NCN view layer's native projection is British National Grid (EPSG: 27700). The Network in Northern Ireland was captured in WGS 84 and reprojected to British National Grid. This is essential for maintaining a complete dataset and for producing overall statistics about the network. For this reason, the public version is projected in WGS 84 / Pseudo-Mercator (EPSG: 3857). Attribute Information 1. DescriptionTrafficFree: Cycle route closed to public motor vehicles such as a footway, cycle path or bridleway.Onroad : Cycle route open to and used by public motor vehicles 2. Route typeNCN (National Cycle Network): Cycle route is signed by a number in a red box. RCN (Regional Cycle Network – network not maintained/updated by Sustrans): Cycle route is signed by a number in a blue boxLink (connects to NCN, but not part of a route): Cycle route is signed by a number enclosed in brackets (blue or red box).PROM: promoted routes, not part of the NCN, but links to NCN and forms part of national or regional routes e.g. John O’Groats to Lands’ End 3. Route category (RouteCat)Main routeAlternative routeTemporary diversion (where a route has been closed for works etc and an temporary alternative route has been designed) 4. QualitySmooth: Top quality asphalt, newly laid path, motorway standard.Standard: Average quality asphalt.Acceptable: Rough British country road or good quality unsealed surface.Rough: Would not normally be ridden on a road bike.MTB Only: A road bike definitely would not be a sensible vehicle for using this section (whether or not it is theoretically possible to cycle on this with enough skill). 5. LightingFullLit: Route link is fully lit, no dark patches.PartLit: Route is part lit, a few dark patches.NotLit: Route is not lit. Additional information on surface type is available on request.

OS Open Rivers is a generalised open water network showing the flow and the locations of rivers, streams, lakes and canals across the whole of Great Britain. The new product is part of the OS Open suite and is designed to be used with other OpenData product sets. It’s mapping that can help you question, visualise and share results quickly and clearly. With OS Open Rivers you can: Understand the water network at a ‘high level’ with generalised geometry and network connectivity.View a network of main rivers, identifying the main river course along its full length.Pin information on the connected network for personal or business use. Take an informed overview of a situation along the network to manage it strategically. Compare and monitor stretches of water. Share information, such as flood alerts and flood risk areas.The currency of this data is 04/2025 The coverage of the map service is GB. The map projection is British National Grid.
