Satellite analysis
Drone scouting is for structure, not for every block
Reserve drone passes for the blocks that already proved they deserve the spend.
Section 1
Drone wins on detail
Use it when the free pass and the first walk both keep pointing back to the same block.
Section 2
Drone loses on cost and schedule
It is the wrong default for every questionable block because it adds time and spend before triage is finished.
Section 3
Start broad, then get closer
The sequence matters more than the tool: satellite first, then field walk, then drone only if the decision remains narrow.
