This dataset is a soil map of England and Wales at 1:250000 scale. NATMAP Vector shows the locations of the 297 distinct soil associations wherever they occur within the countries. Each soil associations has multiple soil series. This hierarchical data structure allows for easy integration with the series-based, non-spatial SOILSERIES data, linking this tabular data with the spatial framework. NATMAP Vector is the most detailed of four versions of the National Soil Map. It is derived from the National Soil Map for England and Wales and is the product of sixty years of soil survey work in England and Wales.
In addition, other NATMAP products are also available, at different prices and scales, including simplified gridded representations, top and subsoil texture, wetness, available water, and soil carbon datasets.

The National Soil Map was published in 1983 after four years of intensive work by the field survey teams of the National Soil Resources Institute. It is the product of free survey with an average of 2 to 3 soil observations per sq km outside areas mapped during more detailed soil survey. A new improved version of the National Soil Map was introduced in 2001. It includes complete urban soil coverage and increased accuracy of line work.
