Detailed River Network (AfA036)

Evidence - Scientific & Evidence Services.

The Detailed River Network (DRN) is the only large-scale, accurate and fully attributed digital river centreline covering England and Wales. The DRN is captured from the water features theme of the OS MasterMap topographic layer and built into a network using automated rules. Other input datasets and extensive local Environment Agency staff knowledge has been used to augment the core geometry to incorporate critical spatial detail and attribution, such as flow direction and path, not available from the OS mapping and to verify the accuracy of the centreline itself. The dataset has full-feature network geometry cross-referenced with OS MasterMap following Digital National Framework principles. This is a spatial dataset.
