This dataset is based on the 1 x 1 km National Soil map data together with data from the CEH Wallingford ( Institute of Hydrology ) on the behaviour of river catchments. There are 29 HOST classes, which describe the dominant pathways of water movement through the soil and substrate.
HOST is NOT scale specific.
Alternatively, a key to HOST classes is available for current leases of 1:250 000 scale and 1 x 1 km soils datasets at +20% of the map data lease charge.
