Spatial variability of soils in the landscape and how this variability is represented by soil maps and portrayed in map unit descriptions are critical for assessing many of today's pressing environmental concerns. Traditional concepts used in mapping, naming, defining and correlating map units need ...
whereas the latter depicts the soil–landscape interaction as a continuum. There are various drawbacks to conventional soil categorization, which adopts a polygon-based soil map unit model. The conventional soil classification technique, according toHartemink et al. (2010), ...

could be translated to at least 2 or 3 soil types in the international (target) system. In this computational notebook we show how to generate a global map of soil types, how to access thepredictions we produced(GB of data), and how to further learn about your own soil. These ...
Geological maps and brief descriptions of regions and quadrangles are available from the US Geological Survey, 1200 South Eads Street, Arlington, Virginia 22202. Generally, the smallest rock unit mapped is a formation, and a geological map indicates the extent of the formation by means of symboli...
VARIABILITY IN THREE AREAS OF THE DENCHWORTH SOIL MAP UNIT This paper shows correlations between soil properties and uses multivariate techniques to investigate similarities between profiles in relation to substrata. It compares laboratory measurements and field observations as means of characte... C. ...

There is no consensus of opinion on theoretical grounds for defining a basic or fundamental unit of soil as a geographic body. There is probably reasonable agreement of such units among field-soil mappers who delineate soils at map scales from about 1:6000—1:12,000. Insofar as practical, ...
Spatial variability within a mapping unit forms a large proportion of this error. The best predictions at point locations were obtained with the representative profile descriptions for the 1:10,000 map.doi:10.1016/0016-7061(89)90059-1A.K. Bregt...
Here we utilise the Harmonized World Soil Database (HWSD), the most up-to-date world soil map (FAO, 2012). It incorporates a data table of 48,148 soil profile descriptions related to the various soils associated with each mapping unit, at a spatial resolution of 30arcsec (approximately 1...
