Abstract:

UNEP/GRID Documentation Summary for Data Set: FAO-Unesco Soil Map of the World; UNEP/GRID 1986 Version. The Global Soils database resident at UNEP/GRID was digitized by the ESRI Corporation in Redlands, California (USA) from the 1974 FAO-Unesco Soil Map of the World at 1:5,000,000 scale. The legend of the Soil Map of the World comprises an estimated 5000 different mapping units, consisting of soil units or associations thereof, occurring within the limits of a mappable physiographic unit (Africa alone in three map sheets has a total of 1509 map units). The number of soil unit classes which compose the FAO-Unesco Soil Map of the World legend is 106. In the UNEP/GRID version, this has been increased to 129 to allow the identification of soils where insufficient information existed to specify the dominant soil unit.* Instead, the dominant soil GROUP is identified (e.g., 'Acrisols' when the dominant Acrisols UNIT is not known). When a map unit is not homogeneous, it is composed of a dominant soil and associated soils, with the latter covering at least 20 per cent of a given area. Important soils covering less than 20 per cent of a given area are added as inclusions. The original FAO-Unesco Soil Map of the World, published in a total of 19 map sheets (including the legend), was in the Bipolar Conic Conformal Projection for the Western Hemisphere, and in the Miller Oblated Stereo- graphic Projection for the Eastern Hemisphere. In order to have a global digital data set that was consistent and uniform, the vector-based data files were first rasterized and then re-projected at GRID-Geneva into the Plate Carree or Simple Cylindrical Projection (a particular form of the Equirectangular). The original digitized polygon vertices in table coordinates were rasterized and georeferenced using the ELAS (NASA's Earth Resources Laboratory Applications Software) programs on a Perkin- Elmer 3241 minicomputer, with an output cell (pixel) size of 30 seconds latitude/longitude spatial resolution (approx. 925 meters at Equator), or 0.86 square kilometers/pixel. The resulting database was also generalized (resampled) to two minutes latitude/longitude resolution (approximately 3.7 km. on a side), yielding an output cell size of 13.7 square kilometers. This is the spatial resolution which UNEP/GRID ( - Geneva) normally recommends to users and most frequently distributes. The original FAO-Unesco Soil Map of the World included information on texture, slope and phase, but separate data layers depicting these variables have not been developed by UNEP/GRID. The proper reference or original source document for this data set is as follows: "FAO-Unesco Soil Map of the World, 1:5000000, ten volumes, Unesco-Paris 1974." The FAO-Unesco Soil Map of the World data file consists of 5400 lines by 10800 elements, with an origin of 180 degrees West longitude and 90 degrees north latitude. At two minutes lat./long. spatial resolution, (approx. 3.67 km. or 30 per degree), the data file covers the entire globe to 180 degrees East and 90 degrees south, and comprises 58.32 Mb. * - There are 106 original Soil Units, and 27 ("Great") Soil Groups; of these, 23 were composed of various soil units and four had ONLY the Group name designations. Therefore, it was only necessary to add 23 new classes to the UNEP/GRID version legend, for 129 in total (106 + 23 = 129). There are three additional categories in the GRID legend for Rock, Salt and Water, or 132 classes altogether.
