OS MasterMap Water Network Layer

OSMM Water Network

Abstract

OS MasterMap Water Network Layer offers one of the world’s most detailed, heighted water networks – showing the flow and precise course of every river, stream, lake and canal in Great Britain. 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.
