Drone LiDAR surveys millions of data points of direct measurements penetrating to the ground through foliage which is far more accurate than indirect measurements mathmatically derived from photographic images

For projects needing civil engineering G.F. Johnston and Associates with whom we have worked on numerous projects throughout eastern Maine for over 15 years is based in Southwest Harbor
We have just upgraded (Oct '25) our LiDAR capabilities with the Rock Ultra in addition to the Rock R3 Pro V2 LiDAR scanner (we've been using for two years) both made by Rock Robotic to drone scan your property locating building, roads/drives, stonewalls/fences, streams/shorelines and elevation contours even under thick vegetation thereby saving many hours and days.
For example, elevation contouring of 30 acres may have taken weeks or months pre-LiDAR can now be accomplished onsite in minutes!
If the survey includes boundary determination, this time savings allows us to focus on the finer details of monumentation evidence recovery such as pins, pipes, buried fencing, etc.
