If you want to do drone mapping, you should definitely read this case.
The Plaintiff offered certain types of services (“weekly flyovers of the developer’s property, capture images, stitch the images together using computer software, and provide [developer] with an updated orthomosaic picture of his property”) that the North Carolina Board of Examiners for Engineers and Surveyors considered unlicensed surveying. The Board told the Plaintiff to stop.
This case followed. This is a First Amendment case (5:21-cv-00137-FL) in U.S. District Court for the Eastern District of North Carolina seeking the court to declare the North Carolina law unconstitutional and stop the North Carolina Board of Examiners for Engineers and Surveyors from further applying the law.
