Detailed description

A geological survey is a systematic analysis of geological properties in a specific area. It provides information on rock composition, soil structures, geological formations and mineral deposits, for example, through methods such as mapping, geophysical measurements or drilling.

If you want to carry out a geological survey, you must notify the relevant authority before work begins. You must also submit the data obtained from your survey to the relevant authority.
