Terrestrial Scanning.
Terrestrial Laser Scanning in California for Buildings, Interiors, and Complex Sites
Aeroskape provides ground-based terrestrial laser scanning to capture dense 3D point clouds of existing conditions for planning, design coordination, and documentation.
Deliverables are provided for informational purposes only and are not certified engineering or surveying measurements.
Drones are excellent at capturing a site from above. But many of the details that matter most on a project sit where a drone can’t see — under roof decks, inside mechanical rooms, along building façades, and beneath canopies and overhangs.
That’s where terrestrial laser scanning comes in.
A tripod-mounted scanner records millions of points from ground level, building a detailed 3D record of walls, ceilings, structure, piping, and equipment.
For architects, general contractors, engineers, and facility owners, this means working from a record of what actually exists on site — not outdated drawings or tape-measure notes.
Paired with our aerial LiDAR and drone photogrammetry services, terrestrial scanning lets Aeroskape capture a project from the rooftop to the basement.
What Is Terrestrial Laser Scanning and How Does It Work?
Understanding the Basics of Terrestrial Scanning
Terrestrial laser scanning (TLS) uses a stationary, ground-based scanner — typically mounted on a tripod — that sweeps laser pulses across a full 360-degree field of view.
Each pulse measures the distance to a surface and records it as a point in 3D space.
The scanner is moved to multiple setup positions around and through the site, and the individual scans are then registered, or aligned, into a single point cloud.
Many scanners also capture panoramic photos, which are used to colorize the point cloud for a true-to-life view of the space.
How Terrestrial Scanning Differs from Aerial LiDAR
Aerial LiDAR looks down. Terrestrial scanning looks across and up.
That difference matters.
A drone-mounted sensor is ideal for capturing terrain, rooftops, and large open areas quickly.
A ground-based scanner captures vertical surfaces, interior spaces, and tight or covered areas where drones can’t fly or can’t see — and, working at close range, it typically records those surfaces in greater detail.
On many projects, the best result comes from combining both.

Key Benefits of Terrestrial Laser Scanning
Capture Existing Conditions Before Design Decisions Get Expensive
Renovation and retrofit projects often rely on original drawings that no longer match what was actually built.
A terrestrial scan documents conditions as they exist today, helping design teams spot conflicts, tight clearances, and discrepancies before they turn into change orders.
Fewer Return Trips to Site
A scan captures everything within the scanner’s line of sight — not just the items on today’s checklist.
When a new question comes up weeks later, your team can often answer it from the point cloud instead of sending someone back out with a tape measure.
Safer Documentation of Hard-to-Reach Areas
High ceilings, elevated structure, and congested mechanical spaces can be captured from the floor.
That reduces the need for ladders, lifts, and working at heights just to document existing conditions.

Applications of Terrestrial Laser Scanning in Construction and Facilities
1. Renovation, Retrofit, and Tenant Improvement Planning
Architects and designers use point clouds as a reference for existing buildings — capturing walls, openings, ceiling heights, and exposed structure to support redesign work.
2. Scan-to-CAD and Scan-to-BIM Support
Point clouds can be brought into CAD and BIM platforms such as AutoCAD and Revit, giving design teams a detailed reference for drawings and models of existing conditions.
3. MEP and Industrial Space Documentation
Mechanical rooms, plant floors, and utility spaces are packed with piping, ductwork, and equipment.
Terrestrial scanning captures that congestion in detail, supporting clash review and upgrade planning.
4. Façade, Structure, and Construction Progress Records
Ground-based scans record building façades, structure before it’s covered by finishes, and job-site conditions at key milestones.
The result is a time-stamped visual record that supports coordination, stakeholder reporting, and dispute resolution.

What You’ll Receive
Deliverables are tailored to your project and software. Typical outputs may include:
- Registered, colorized 3D point clouds
- Industry-standard formats such as E57, LAS/LAZ, and RCP/RCS for Autodesk ReCap
- 360-degree panoramic imagery of scan locations
- A shareable web viewer link for stakeholders without CAD software
- Optional 2D drawings or 3D models developed from the point cloud
Choosing the Right Terrestrial Laser Scanning Provider
Match the Equipment and Deliverables to Your Project
Ask any provider what scanner and registration workflow they use, and what the equipment is rated for.
Confirm that their deliverable formats open cleanly in the software your team already uses.
Ask to see sample data from a similar building or site before you commit.
Know Whether You Need Reality Capture or a Licensed Survey
Not every scanning project is a survey — and in California, the difference matters.
Work that determines property boundaries or establishes the authoritative position of land and fixed objects falls under licensed land surveying.
A good provider will be clear about which side of that line your project falls on, and will bring in a Professional Land Surveyor when it’s required.
