An eco-hydrological modelling parameters dataset derived from the Soil Map of Estonia.
We have developed the EstSoil-EH dataset as a machine-readable and enriched version on the base of the Soil Map of Estonia.
The national soil map is a vector dataset that maps more than 750.000 soil units throughout Estonia at a scale of 1:10.000. It is the most detailed and information-rich dataset for soils in Estonia. For each soil unit, it describes the soil type, quality, texture, and layer information with a series of complex text codes. However, to use it as an input for numerical modelling using process-based physical models, these text codes must be translated into extract and derive numerical values and exact classes, for example such as:
- soil profiles (e.g., layers, depths)
- texture classes and percent of fine earth fraction (clay, silt, sand components)
- coarse fragments and rock content
- physical variables related to water and carbon (bulk density, hydraulic conductivity, organic carbon content)

During the review process several original attributes, such as “värv” had to be dropped as they didn’t fulfill a function and we couldn’t justify its use case to the reviewers (or any international audience). A version with this attribute joined back in is available on request. Please get in touch if you would like to use original soilmap attributes together with EstSoil-EH.
