OS Open Rivers

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.
