1. Attribute values are classified, e.g. DR = Depth to rock. S = Shallow ( < 40 cm) M = Moderate (40 - 80 cm) D = Deep (80 - 120 cm) V = Very deep ( > 120 cm) The value of an attribute P within an SMU could be given according to : Dominant STU principle For each SMU : a dominant STU is associated. The value of a attribute P (e.g. depth-to-rock) for that SMU would be the value that P has within that dominant STU Dominant value principle For each SMU and for a attribute P : the value of P is that class value that appears most within the SMU Marc Van Liedekerke, JRC Ispra

2. European Soil Raster Maps (on eusoils.jrc.it) 3 sets of 73 raster maps based on attributes in ESDB v2 raster cells 10km x 10km 3 sets : Set aligned with MARS grid, dominant value Set aligned with MARS grid, dominant STU Set aligned with INSPIRE grid, dominant value Features to raster tool in ESRI ArcGIS Spatial Analyst Limitations to agricultural use FAO and WRB Soil coding Impermeable layer presence Parent material Depth class of an obstacle to roots Slope class Depth class to a textural change of the dominant and/or secondary surface texture Surface and sub-surface textural class Dominant and secondary land use Code for normal presence and purpose of an existing water management system in agricultural land on more than 50% of the STU. Type of an existing water management system. Dominant annual average soil water regime class Maximum and Minimum elevation above sea level Accumulated temperature class. Available water capacity of the topsoil and subsoil Base saturation of the topsoil and subsoil Cation exchange capacity of the topsoil and subsoil Soil crusting class Depth to a gleyed horizon Soil profile differentiation Depth to an impermeable layer Depth to rock Easily available water capacity of the topsoil and subsoil Soil erodibility class Hydrogeological class Profile, topsoil and subsoil mineralogy Organic carbon content of the topsoil and subsoil Packing density of the topsoil and subsoil. Peat Physi-chemical factor of soil crusting & erodibility Parent material hydrogeological type Structure of the topsoil and subsoil Rule infered subsoil texture. Dominant surface textural class Textural factor of soil crusting Textural factor of soil erodibility Regrouped land use class Volume of stones Marc Van Liedekerke, JRC Ispra

3. Also.. (on eusoils.jrc.it) THE MAP OF ORGANIC CARBON IN TOPSOILS IN EUROPE 1k x 1k Marc Van Liedekerke, JRC Ispra

4. Also.. (on eusoils.jrc.it) Pan European Soil Erosion estimates (t/ha/yr) from the Pan-European Soil Erosion Risk Assessment (PESERA) project 1k x 1k Marc Van Liedekerke, JRC Ispra

5. What can JRC do for the project? generate from the ESDB v2 : 1k x 1k raster maps, using the Features to raster tool in ESRI ArcGIS Spatial Analyst for selected attributes dominant value or dominant STU (only 3 to 6 % different cell values) any projection any grid origin document the maps Marc Van Liedekerke, JRC Ispra
