S-map Soil Drainage

S-map Soil Drainage is part of the S-map digital soil map for Aotearoa – New Zealand. 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 water logging and reduction. The S-map Soil Drainage layer is a "dissolved" representation of the soil depth attribute for S-map soils previously available as a lookup table. This layer was updated Aug 2021.
