Every survey is a negotiation between four numbers: how fine you need the ground sampling distance, how tight the accuracy has to be, how much ground has to be covered, and how long you are willing to wait. Fix any three and the fourth is decided for you.
We publish the relationships rather than the marketing. The chart below is the same one our planners use to pick an altitude, and the flight geometry panel is why a corridor costs more per hectare than a block. Neither is a picture — both are computed from the sensor geometry.
Choosing an airframe
Airframe follows tolerance, not the other way round. Above 150 hectares the fixed-wing is the only economic answer. Under a canopy the scanner is the only technical one. On a structure, the close-range platform is the only thing that can get near enough without touching it.
Crew and currency
Every flight is crewed by a remote pilot and an observer. Pilots hold current type authorisation on the airframe they are flying, and every mission is logged with its airspace approval, its risk assessment and its post-flight coverage check.
