James Hutton Institute data sets contributing or derived from the National Soils of Scotland database.

Soil maps display the distribution of different soil types across the land based on what you can see in the field. The amount of detail shown on a map depends on its scale. For example, smaller scale maps (e.g. 1:250,000) will show less detail than larger scale maps (e.g. 1:25,000). More detailed 1:25,000 maps are also available for much of Scotland’s cultivated agricultural soils and the adjacent uplands and only provide partial cover of Scotland.
