OS MasterMap Water Network

Every river, stream, lake and canal in Great Britain

OS MasterMap Water Network is the only detailed, heighted water network of Great Britain showing the flow and precise course of rivers, streams, lakes and canals. It supports flood risk management and is ideal for data sharing.

OS MasterMap Water Network

From aqueducts to tunnels, with annotations of flow direction, OS MasterMap Water Network Layer provides the detailed mapping that’s most useful – including underground watercourses (inferred from entry and exits).

Proximity is key. Organisations can understand water-related risks in detail, combining OS MasterMap Water Layer with OS MasterMap Topography Layer, property information and 3D height data for even richer insights.

For planners, for surveyors, for engineers – this Layer offers the potential to model in 2D and 3D like never before, thanks to the clarity of river flow, gradient and river widths.

OS MasterMap Water Network is released quarterly in January, April, July and October.

Answers on Tap

With OS MasterMap Water Network, you can look up the height of any water course, along with its flow direction, gradient, length and width anywhere along its length.

As an island, water defines Great Britain. No other visualisation of our nation’s watercourses details the heights of watercourses in relation to sea level with this level of precision.

OS MasterMap Water Network provides a detailed centre line following the curve of the waterway precisely. It includes the coordinates of watercourse sources and where they meet, exactly.
