River Network Centrelines
Data already available
This data request has been included in the work ODUG is undertaking on third party licences and River Networks Centrelines. For further information, please see http://data.gov.uk/open-data-user-group-benefits-cases-for-release-of-data
Data request description:
A vector-based mapping data set of centrelines of rivers and other watercourses in England and Wales, segmented and attributed with local names of the watercourses.
There are financial charges for the data
There is no authoritative vector-based open data mapping available for the river network in England and Wales. This data currently exists as a subset of the Environment Agency's Detailed River Network (DTN) data product, derived primarily from the water features theme of Ordnance Survey's OS MasterMap Topography Layer. (Both of those products are available for licensing on commercial terms.). This request is specifically for open data release of the centreline data, minimally attributed with names of watercourses, and not for release of the complete DTN data set.
Vector mapping of the river network is a noticeable gap in open geographic data for England and Wales. Since the release of the OS OpenData product suite in 2010 the public has had access to freely re-usable data for administrative boundaries, postcode locations, the road network and the rail network. Addition of the river network would help to complete the picture for existing open mapping initiatives such as OpenStreetMap, and support numerous other geographic applications.
Release of this data would enhance leisure applications, tourism and outdoor pursuits. Enabling developers to include the river network as a standard layer on free web-based maps would also help familiarise the public with names and locations of their local watercourses. This would support greater awareness of flood risk and environmental concerns associated with rivers and streams.
