Abstract: There is a constant need for the rational evaluation of every individual piece of land. To provide continuously upgraded, precise technical and economic assessment, an online digital geographic information system was developed. At the roots of the system are cadastral maps from the land registry and soil maps at the scale of 1:10,000. The basis of the technical land bonitation* is the D-e- Meter system, which is used not only for croplands but also for grasslands and forests.
