131M American Buildings

An IDF counterinsurgency bombing campaign.

The precision with which Israel have exacted what appear to be controlled demolition of structures strongly suggests to me that targeting teams have fairly accurate ideas of building structure and critical weak points, to the point that they know specifically where, and how many times, to hit a structure to collapse it.

Accurate mapping + structure data plus precision munitions is what makes such strikes possible.

Cartography was long considered national-security-level critical data, a situation only mooted by satellite surveillance beginning in the 1960s.

This was exactly what I thought. Not sure why you're being downvoted. Granted it's not very useful if you're just an average citizen.

Establish yourself in non-mapped structures is actionable.

Knowing when you're in a mapped structure is actionable.
