The National Soil Inventory (NSI) site data is a spatial, point dataset with 6,127 points, located in a 5km grid across England and Wales.
NSI Site provides a in depth description of the general land features at each of the NSI points across England and Wales.
NSI Site contains data on the land use, slope, slope form, human influence on the landscape, rock outcrops, the altitude, aspect, erosion and deposition features and a description of the rock type. As such, NSI Site gives a comprehensive description of the sites in which these inventory points were taken.
NSI Site has proved useful for those who would like to have a good picture of the landscape across these two countries, for instance in a project examining the link between erosional features and the amount of Carbon in the upper 15cm of soil.

LandIS, or the Land Information System is one of the offerings of the Soil and Agrifood Institute. Incorporating the National Soil Resources Institute, CSAI is the largest UK national and international centre for research and development, consultancy and training in soils and their interaction with the atmosphere, land use, geology and water resources.
