Top-down view of the same boustrophedon (back-and-forth) survey pattern: camera/spray footprint (swath) grows with altitude and field of view, and battery drains with speed and altitude.
swath = 2·h·tan(FOV/2)
coverage% = area_covered / area_field
battery(t) = 100 − k·(v² + h)·t
- Flight altitude — higher flight widens the swath but lowers spray precision.
- Flight speed — faster coverage, higher power draw.
- Spray rate — nozzle flow; controls droplet density and liters consumed.
- Camera FOV — wider lens/sensor angle widens the swath at a given altitude.
- Fly / NDVI toggle — start/stop the survey; NDVI mode recolors the field by simulated plant health.
