Finistère soil mapping units

Representation of the contours of the 113 soil mapping units (also known as UCS or soil landscapes) of the Finistère. Each UCS, consisting of one or more polygons, is defined as a portion of landscape in which the factors of soil genesis (parental material, morphology, climate, soil occupancy) are homogeneous. This layer of information is part of the Regional Soedological Reference (1/250 000)
