SoilGrids1km is a collection of updatable soil property and class maps of the world at a resolution of 1 km produced using state-of-the-art model-based statistical methods. Presents estimates (means and 90% confidence intervals) for pH, texture (sa, si, cl), organic carbon and more for 6 depth layers up to 2 m depth. Harmonized World Soil Database
The FAO soil map was intended for mapping soils at a continental scale but not at local scale. In 1988 the FAO published a Revised Legend with 153 Soil Units forming 28 Major Soil Groupings. It serves as basis for the Harmonized World Soil Database. In 1998 this system was replaced by the World Reference Base for Soil Resources.

The European Soil Database is the only harmonized soil database in Europe from which many other data information and services are derived. For instance, the European Soil Database v2 Raster Library contains raster (grid) data files with cell sizes of 1 km x 1 km for a large number of soil related parameters. Each grid is aligned with the ...
ISRIC is a regular member of the ISC World Data System, and is known as WDC-Soils since 1989. [4] ISRIC's main open access databases include WoSIS, [ 5 ] a large database of quality-assessed and standardised soil profile data for the world, that has been used for producing soil property maps at 250 m resolution, with quantified uncertainty,for ...
The archive is typically unique at the present times, for it is the only archive that holds nearly 6000 maps online related to soils and are freely accessible to the public around the world. Moreover, the major focus of the EuDASM initiative is towards the developing nations of Africa , South America , Asia etc., in order to assist them to ...
Digital soil mapping (DSM) in soil science, also referred to as predictive soil mapping [1] or pedometric mapping, is the computer-assisted production of digital maps of soil types and soil properties. Soil mapping, in general, involves the creation and population of spatial soil information by the use of field and laboratory observational ...
World Census of Agriculture; Contains structural data from agricultural censuses conducted since the 1930s, under the decennial World Programme for the Census of Agriculture. Structural data include the size and number of agricultural holdings, the holder’s gender, the type of land tenure, the legal status of holders, as well as information ...
