For aerial surveillance on utility yards, I’m running 70 m AGL, about 6 m/s, 75% overlap on a Matrice 30T, and I’m looking for a concise reference that ties wind and altitude to leg spacing and dwell for reliable human/vehicle detection. If you’ve got a field-tested sheet or calculator you trust, I’ll adapt it to this profile and share back results.
At 70 m AGL on the M30T, I’ve had good hits using about 25–30 m leg spacing and 5–6 m/s, keeping “3–5 pixels across a human” as the sanity check. If the crosswind tops 6–7 m/s I either slow to about 5 m/s or bump sidelap to 80% to keep dwell per target up; hot gravel yards push me to the latter. I’ve got a one-pager based on that rule-of-thumb — happy to DM it; it’s more duct tape than PhD.
