<p>This data comes from the HWSD World Soil Database and covers soil attribute classification data sets in five Central Asian countries and Xinjiang. Attributes include sand, loam, clay and PH values. The projection coordinates use GCS_WGS_84 projection coordinates, with a spatial resolution of 1000 meters. </p>
The data comes from the International Institute for Applied Systems Analysis (IIASA) and the Food and Agriculture Organization of the United Nations (FAO) and the Kyoto Protocol on soil carbon measurement and the FAO/International Global Agroecological Assessment Study (GAEZ v3.0) to establish a new generation of World Soil Database (Harmonized World Soil Database version 1.2 ) (HWSD V1.2).
Unique verification identifier for core soil system unit: MU_GLOBAL-HWSD database soil mapping unit identifier, connected to GIS layers. MU_SOURCE1 and MU_SOURCE2-Source database mapping unit identifier SEQ-sequence of soil units in the composition of soil mapping units; soil classification systems use the FAO-7 classification system or the FAO-90 classification system (SU_SYM74 resp. SU_SYM90) FAO-85(SU_SYM85)。
