| Evans, J A, Mee, K, Chenery, C A, Cartwright, C E, Lee, K A, and Marchant, A P. 2018. User guide for the Biosphere Isotope Domains GB (Version 1) dataset and web portal. British Geological Survey. (OR/18/005). |
Scale
The dataset is represented by 1 km hexagon cells and has been derived from the BGS Geology and BGS Soil Parent Material data, both 1:50 000 in scale and therefore providing 50 m ground resolution.
