Soils of Brittany — Map of Naizin soils at 1/10000

Soil map of Naizin at 1/10000. The coding corresponds to code 4 soil criteria of the Armoricain Massif (see online resources). The fields of the successful table are: — SUB: Parent material(s) from which the soil develops — HYD: Hydromorphic class, 0 (well drained soil) to 9 (extremely hydromorphic soil) — TYPE: Profile development defined from the succession of horizons — TEACHER: Soil depth, classified from 1 (very thick soils) to 6 (surface soils) — CODE4C: code 4 criteria derived from the concatenation of the previous fields. The values taken by the different fields for each entity are detailed in the 4 criteria method (see online resources). — UTS: Soil Typological Unit number from the Regional Pedological Reference Office of Brittany.1:10000比例尺的奈赞（Naizin）土壤图。 该数据集采用的编码体系对应阿莫里卡地块（Armoricain Massif）的4类土壤分类标准，详细信息参见在线资源。 有效数据表包含以下字段： — SUB：土壤发育所依托的母质 — HYD：水成土等级，取值范围为0（排水良好的土壤）至9（极端水成土） — TYPE：由发生层序列定义的土壤剖面发育程度 — TEACHER：土壤深度，分级标准为1（极厚层土壤）至6（表层土壤） — CODE4C：由上述字段拼接得到的4类土壤分类标准编码。 各实体各字段的具体取值详见4类分类标准方法文档，详细信息参见在线资源。 — UTS：布列塔尼大区土壤学参考办公室划定的土壤类型学单元编号。
