Kearsey, T, Lee, J R, and Gow, H. 2019. Buried valleys (onshore) - Version 1: scientific report and methodology. British Geological Survey Internal Report, OR/19/003.

Data description

The buried valley dataset is provided in three GIS format (ESRI shapefiles) layers. For ease of use the layers should be displayed in the following order:

• Buried Valley Historic centerlines
• Buried Valley Historic margins
• Modelled Thickness of Buried Valleys

Scale

The buried valley dataset is produced for use at 1:250 000 scale providing 250 m ground resolution.

Field descriptions

Each buried valley theme (GIS map layer) contains a series of attribute fields specific to the data they contain for example the historic buried valleys include a reference field describing the data source.
