Overview of the structure of the European soil hydraulic properties database HYPRES. Each column represents a separate table linked by geo-reference and horizon.
HYPRES Version 1.1 has 5 additional fields in the BASICDATA table; FAO (1994 soil classification), COORD_TYPE (local georeferencing system), VEG_ORIGINAL (original V1 land cover description), VEG_RECODE (a reclassification of the original land cover in a hierarchical system), PM_RECODE (a reclassification of the original soil parent material in a European hierarchical system).
