MAP UNIT CLASSES
The soil scientist who maps a given territory would prefer to be able to delimit “pure” map units, in other words, those corresponding to a single taxonomical unit. Unfortunately, this is not usually possible and complex map units consisting of more than one taxonomical unit must often be represented.
The objective of a soil map, the complexity of the soil distribution pattern within the landscape and the map scale make it necessary to establish different kinds of map units.
The main map units used are as follows:
– the simple unit, characterised by a single soil class;
– soil consociations;
– soil complexes;
– soil associations;
– undifferentiated soil groups;
– taxadjuncts;
– miscellaneous areas;
