  1. Mogens Humlekrog Greve Danish Institute of Agricultural Sciences Improving the Danish Soil Information System

  2. Subjects • Introduction • Existing data • Combining point and area data • Generating a two layer soil model • Generating soil attributes • Conclusion Mogens Humlekrog Greve

  3. Introduction, the aim The aim of the project is to establish a nationwide geographical database containing information on top- and subsoil of basic soil parameters in a scale of 1:50 000

  4. Introduction – method The database will be constructed by combining a number of existing maps with large number of point data. Mogens Humlekrog Greve

  5. Existing data, Topsoil point data

  6. Existing data, Topsoil map

  7. Existing data, Subsoil map Geological soiltype 1:50000 evaluatede in 1 meters dept

  8. Existing subsoil data, 2000 Soil profiles

  9. Existing data, Profile data

  10. Generating a two layer soil model Eight soil types 40 000 point Topsoil 30 cm Subsoil Thirteen geological soiltypes and 2000 soil profiles

  11. Generating attributes for the topsoil

  12. Generating attributes for the subsoil

  13. Conclusion,1 Minimizing the within class variance

  14. Conclusion,2 Cartographical difficulties

  15. Conclusion,3 We continue to work with system
