Construction area bomb drop zone

No, we did not pay anything for the request.

No result meant in essence: An aerial image analysis was not possible due to the lack of aerial images. So please dig carefully when earthworks are deeper than 40cm.

By forced search I mean: If a suspicion arises during aerial image analysis, the building authority can force the builder to commission an appropriate metal detector for the survey. But I am not really familiar with that. Dangerous half-knowledge read off.

Understood, still interesting, so thanks!
