NSI Site data showing carbon levels in Yorkshire

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.

How much does this product cost?

  • £600 for each individual property across England and Wales;
  • £10 per point, all data for that point (discounted for more than 50 points);
  • £3,500 for the whole dataset.
