National Soil Map of England and Wales - NATMAP


National Soil Map - Vector Data Version

NATMAP Vector is the principle soil data product held at Cranfield University. It is a 1:250,000 scale map of England and Wales, showing the locations of the 297 distinct soil associations wherever they occur within the countries. Within each of the soil associations are multiple soil series. This hierarchical data structure allows for easy integration with the the series-based, non-spatial SOILSERIES data, pulling this tabular data also in the the spatial framework.
