National Soil Map

The National Soil Map is the flagship soil data product from 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. The types of soil are described, along with attributes such as the soil fertility and drainage. General descriptions of the underlying geology and typical cropping and landuse are also provided. A URL link to extremely detailed supplementary soil information is also included.

Who and what is this useful for?

  • The National Soil Map is useful for anyone wanting soil information at 1:250,000 scale.
  • The National Soil Map is essential for evidence-based land management and planning across England and Wales.
  • The National Soil Map is being used by most of the major water companies, many universities, consultants and governmental bodies.

Enhanced Natural Perils Directory

Cranfield University have developed an easy-to-use and unique suite of geohazard datasets, the Natural Perils Directory (NPD), to assist the insurance market with risk-management decisions on multi-hazard subsidence, flood and wind. Their data is derived from the UK Government recognised National Soils Data and Land Information System (LandIS).

The enhanced Natural Perils Dataset benefits from the addition of highly detailed and accurate tree location data uniquely provided by Bluesky International. Including all trees in England and Wales over 3 metres in height, it enables an unprecedented level of risk assessment for subsidence.

Hydrology of Soil Types (HOST)

The Hydrology of Soil Types (HOST) classification describes the dominant pathways of water movement through the soil and, where appropriate, the underlying substrate. Eleven drainage models are defined according to the permeability of the soil and its substrate and the depth to a groundwater table, where one is present. These are further subdivided into 29 HOST classes to which all soil series have been assigned. These classes identify the way soil water flows are partitioned, with water passing over, laterally through, or vertically down the soil column. Analysis of the river hydrograph and the extent of soil series for several hundred gauged catchments allowed mean values for catchment hydrological variables to be identified for each HOST class.

Who and what is this useful for?

The HOST classification is widely used to predict river flows and the frequency and severity of flood events and also to model the behaviour of diffuse pollutants.
