In 1990 a Map of World Soil Resources was completed at scale 1:25.000.000,
generalized from the FAO/UNESCO Soil Map or the World at scale 1:5.000.000
(FAO, 1971 - 1981).
The map was issued on the occasion of the 14th International Congress of Soil
Science held in Kyoto, Japan in 1990. Since then new material has become
available, the FAO/UNESCO Soil Map of the World has been partly updated under
the SOTER Programme and the FAO legend has been replaced by the World Reference
Base for Soil Resources (WRB). In 1998 the latter was adopted by the
International Union of Soil Sciences as the standard for soil correlation and
nomenclature. In the light of these new developments it was decided to prepare
an updated version of the generalized Map of the World Soil Resources at
1:25.000.000.
The updating exercise covered:
- the switch from the original map projection to a Flat Polar Quartic
projection
- the conversion of the FAO legend into the WRB classification
- the incorporation of additional soil data obtained from new or revised soil
map sources
- the matching, when possible of soil unit boundaries with major landforms
