Field Mapping & Obstacle Marking

Ninety percent of drone spray accidents are obstacle strikes. The fix isn't better reflexes โ€” it's a better map.

Map before you fly, every field, every season. Fields change: new irrigation, a new pole, a beehive that wasn't there last year.

Boundaries done right

Walk or drive the perimeter with the controller's mapping mode, or import the boundary from your FMS/shapefile. Don't map to the fence โ€” map to the crop edge, then decide your headland treatment. Save named boundaries per farm/field so year two is a two-minute setup.

The obstacle list to mark every time

No-spray zones & buffers

Draw exclusion polygons for water, sensitive crops (grapes, tomatoes, organic ground), homes, and hives โ€” sized to the label's buffer for the product and your droplet class. Modern flight software will fly the boundary and skip the polygon automatically; that's a compliance record you can hand a customer. More: drift management.

The pre-flight walkthrough (do it anyway)

  1. Drive the field edge and look up โ€” software doesn't see a wire that isn't in the map.
  2. Note wind direction relative to your exclusion zones; plan pass direction accordingly.
  3. Pick launch/recovery point with clear approach and space for the crew.
  4. Photograph anything unusual and attach to the job record.

Terrain following

On rolling ground, constant AGL beats constant altitude: too high increases drift, too low risks a strike. Enable terrain-following (radar or DEM-based) and verify it with a slow first pass on unfamiliar ground โ€” see RTK precision.

General operational practice; follow your platform's mapping documentation and airspace rules (LAANC guide).
