Drone & Laser Scanning
Drone LiDAR and photogrammetry, laser scanning, orthophotos and 3D surfaces, all tied to real survey control.
What we do
Services
Six services, from drone and laser scanning to tunnel surveys and original 1800s corners. Pick the one that fits, or request a quote and we will help you choose.
Precision Layout
Control, grid lines, anchor bolts and embed plates for plants, structures and buildings, with as-built checks before the pour.
Deformation Monitoring
Repeat epochs on structures, walls and slopes during construction, compared to tolerance and reported so crews can act the same day.
Tunnel Surveys
Control carried underground, line and grade at the heading, and scans of the excavated profile where GNSS can't follow.
Boundary & ALTA Surveys
Hard boundary problems, original 1800s government corners, records of survey and ALTA/NSPS surveys on 1,000 to 5,000+ acres. Expert witness work, too.
Mountaintop Topographic Surveys & Control
Atop Mammoth Mountain, we mapped the site for a new communication tower and tied it by geodetic control to Mammoth Pool, six hours away by road across the Sierra, so the antennas could be aimed precisely.
