The minimal geodata model specifies the structure of the official geodata for dams and reservoirs under the supervision of the federal government. The term "dams and reservoirs" refers to installations designed to dam or store water or mud. Facilities which meet the criteria specified in the Dam Safety Ordinance are subject to the direct supervision of the federal government.
The minimal geodata model is explained in detail in the documentation. The INTERLIS 2.3 data model and geodata are available for downloading.
