A continuous centreline network of rivers, canals and field drains for Great Britain. The Centre for Ecology & Hydrology’s 1:50,000 watercourse network was derived from Ordnance Survey 1:50,000 maps and was the first continuous digital river network to be produced for Great Britain.

The 1:50,000 watercourses has been used to define flow paths in CEH's Integrated Hydrological Digital Terrain Model (IHDTM), which in turn is used to define drainage paths in the Flood Estimation Handbook CD-ROM.

Released in July 2011, Land Cover Map 2007 (LCM2007) is the latest land cover map to be produced by the Centre for Ecology & Hydrology. It covers the whole of the UK.

Over the last 20 years, CEH has produced three digital land cover maps: LCMGB 1990, LCM2000 and LCM2007. Each of these land cover maps has been produced as a number of different products with varying data formats and spatial resolutions. All of the products of the three land cover maps can be obtained from CEH under licence for academic, non-commercial and commercial use.

A 50m grid interval DTM derived by the Centre for Ecology & Hydrology from 1:50,000 scale mapping from Ordnance Survey and Land & Property Services (previously OSNI). The IHDTM is comprised of five separate gridded datasets.

Each IHDTM grid is hydrologically consistent with the other IHDTM grids and with the CEH 1:50,000 Watercourse Network dataset.

The five gridded datasets are -

The Scottish Environment Protection Agency’s maps show where flooding may happen across Scotland so that individuals and groups can take appropriate action.

Flood Maps (NI) is an interactive map-viewer that enables users to access the latest flood hazard information available from government for the whole of Northern Ireland.

The map highlights the areas throughout Northern Ireland that are prone to flooding and its potential adverse impacts.
