A company offered to survey my land with a drone. Is that a real survey?

A drone can be an excellent mapping tool, but it doesn't replace a boundary survey [1].

What drones do well:

  • quick aerial maps (orthophotos), contours and volumes over large open areas,
  • topographic data where the ground is visible [3].

Limits:

  • Boundaries: property lines are established from records and monuments by a licensed surveyor. A photo can't do that.
  • Vegetation: trees and tall grass hide the ground, though LiDAR helps more than photos do.
  • Accuracy depends on ground control points and checks [2].
  • Licensing: in many states, mapping that is sold as a survey must be done or supervised by a licensed surveyor.

Ask who the licensed surveyor in charge is, what accuracy the data will meet, and how it will be independently checked.
