Data protection statement in connection with the use of drone technology

Information about how your personal data are processed in accordance with Art.13 GDPR in connection with the use of drone technology for surveying

You have seen one of our documentation and surveying drones or a sign – we would like to inform you about the background:

The creation of terrain models with the help of drones flying over the terrain as well as the documentation of the progress of construction on large building sites is an economical alternative to surveys carried out using conventional GPS technology or the documentation of construction work by hand.

The existing topography is measured and recorded by means of drones flying over the relevant areas and subsequent analysis with the aid of software by our engineers. We focus on previously marked / identified areas of construction sites when doing so.

Art. 13 GDPR requires us to inform you about the possible processing of personal data as follows.
