There has been a change in the way the S-map is being made available to users. The S-map primary map layer ofsoil classes (i.e. delineated areas that are labelled with the soil family name) is no longer freely available to commercial users. Access to this data and associated soil attribute data for commercial use is by negotiation - please contact Graeme Anderson. This layer is a "dissolved" representation of the soil drainageattribute for S-map previously available as a lookup table.It is available for non-commercial use under a creative commons licence (CC-BY-NC-ND).Soil drainage is a relatively simple classification of the soil profile that describes the likelihood of seasonal wetness. It is based on the occurrence within specific depths of redox segregation and low chroma colours indicative of waterlogging and reduction (Webb and Lilburne, 2011).Very poorly drainedPoorly drainedImperfectly drainedModerately well drainedWell drainedWebb TH, Lilburne LR 2011.
