These products provide information about the spa tial variation of many factors associated with geology\, natural resources \, soil health\, climate\, topography and the potential occurrence of natu ral hazards. These products might be integrated within mathematical\, stat istical or machine learning models to answer specific questions regarding the need to protect the land because of its value for productive agricultu re or mineral exploitation\, the potential hazards associated with develop ing the land and the suitability of sites for particular types of infrastr ucture. The British Geological Survey produces many two- and three-dimensi onal data products (see https://www.bgs.ac.uk/data/mapView ers/home.html). We also integrate these products in decision support t ools addressing many land-use questions such as the suitability of land fo r sustainable drainage schemes\, the need for remediation of brownfield si tes\, the suitability of land for renewable energy production and queries regarding the cost and environmental impacts of major infrastructure proje cts. I will describe examples of such decision support tools particularly focusing on the issues of uncertainty in the products used to create them\ , the propagation of this uncertainty upon integration of these products a nd the potential for a mismatch of scales between the different products a nd the policy question being addressed. I will discuss strategies to addre ss these issues and the information and metadata that must be provided wit h data products to facilitate such strategies.
