Terrestrial LiDAR scanning
An aircraft sees the top of the world. Some of the answers are underneath it. Terrestrial scanning fills in the garages, the balcony undersides, the interiors and the tight geometry the aerial pass cannot reach.
The half of the building the aircraft cannot see.
On restoration work the underside of a balcony, the soffit condition, the garage structure and the interior of a mechanical space are frequently the whole point. None of those are visible from above at any altitude.
We register the terrestrial data into the same control frame as the aerial collection, so the result is one model rather than two datasets that approximately agree. That is what makes it usable for take off instead of just for reference.
What you get back
- Registered terrestrial point cloud
- Combined aerial and terrestrial model on one control frame
- Interior floor plans traced from the scan
- Sections and elevations to CAD
- Clearance and dimension checks
- Panoramic imagery tied to scan positions
- Registration report with residuals
- Archive files with capture date
How ground scanning runs
Scan positions planned for coverage
Positions set so the overlaps close and the shadows do not stack up. Under structured concrete that means more setups, and we plan for them rather than discovering them on site.
Targets or cloud to cloud registration
Whichever holds tighter for the geometry in front of us, with residuals reported so you can see how the registration actually performed.
Tied to the aerial control
The same observed control frame carries both datasets, which is what lets you measure across them.
Working around occupancy
Occupied buildings stay occupied. Scanning is quiet, it does not need scaffolding, and it does not close a lane or a lobby.

Data from delivered work.
Every image below came off a real collection. Nothing here is a stock render or a vendor sample.
Where this work goes.
Common questions.
Do you have to close the building or the area?
How long does a scan take?
Can this replace the aerial flight?
Often collected on the same trip.
Aerial LiDAR mapping
Classified point cloud, bare earth under canopy, contours and Civil 3D surfaces from a single flight.
Read more →Photogrammetry and orthomosaics
Orthorectified imagery and colorized 3D mesh, tied to the same control as the LiDAR.
Read more →Digital twins
A measurable copy of the building on your server, so the next question does not need another trip.
