This dataset contains 10 maps that relate to the soil's storing and filtering capacity in Europe (the EU only):
- cation storing capacity (STOR_CAPCA)
- cation filtering capacity (FILT_CAPCA)
- anion storing capacity (STOR_CAPAN)
- anion filtering capacity (FILT_CAPAN)
- solids and pathogenic microorganisms storing capacity (STOR_CAPSO)
- solids and pathogenic microorganisms filtering capacity (FILT_CAPSO)
- non-polar organic chemicals storing capacity (STOR_CAPNP)
- non-polar organic chemicals filtering capacity (FILT_CAPNP)
- nonaqueous Phase Liquids (NAPL) storing capacity (STOR_NAPL)
- nonaqueous Phase Liquids (NAPL) filtering capacity (FILT_NAPL)
As input, variables from the European Soil Database have been used. The calculation is described in detail in the JRC technical report "Makó, A., Kocsis, M., Barna, GY., Tóth, G. 2017. Mapping the storing and filtering capacity of European soils
; EUR 28392; doi:10.2788/49218; P54; Publications Office of the European Union, Luxembourg".
The calculated values were converted to a 10-point scale, where the code 1 represents the lowest and the code 10 the highest capacities. To transform the estimated values (continuous scale cariables) into this limited number (10) of distinct categories the Visual Binning method was used (SPSS, Transform, Visual Binning, Equal Percentiles Based on Scanned Cases). This method generates binned categories with an equal number of cases in each bin using the aempirical (empirical distribution function with averaging) algorithm for percentiles.
The 10 maps come as 1 shapefile with an attribute table that contains10 fields corresponding to the 10 parameters mentioned above.
The geometry of the shapefile is the one of the European Soil Database.
Two versions are available:
- a shapefile with only the resulting 10 parameters;
- a shapefile with the resulting 10 parameters plus all the intermediate parameters that were used to derive the output from the input parameters.
These data/maps have been elaborated to the best of JRC’s knowledge. They are based on data publicly available in ESDAC, but the resulting dataset itself was never published for public or peer-reviewed scrutiny.
This study was conducted under the supervision of Gergely Toth.
Below is one example of the "Map of the solids and pathogenic microorganisms storing capacity of European soils", as reported in the study mentioned above:
