SLAM LiDAR Scanning in Southern Ontario

SLAM LiDAR Scanning and 3D Point-Cloud Data

Geo Vision Surveying Inc provides SLAM LiDAR scanning and 3D point-cloud capture for existing-conditions documentation, renovation planning and construction as-builts. We work with engineers, architects, contractors and property owners to define the area to capture and the data needed. On construction projects, SLAM LiDAR records existing conditions before design and captures what was built for as-built checks.

What Is SLAM LiDAR?

SLAM (simultaneous localization and mapping) LiDAR is a mobile laser scanner that is carried through a building or site. It maps the space as it moves, producing a dense 3D point cloud without setting up at every room or corner. That makes it fast for interiors, mechanical rooms, multi-level buildings and cluttered sites where traditional setups would take much longer.

What's Included

• Scope review: the area to scan, access, required coverage and the intended use of the data.
• Control and tie-in: where the project needs it, the scan is tied to site control measured by robotic total station or GPS/GNSS, so it lines up with your drawings.
• Field capture: walk-through scanning of the agreed areas, inside and out.
• Processing: registration and cleaning of the point cloud.
• Deliverables: point clouds and CAD drawings in the agreed formats.

When You Need LiDAR Scanning

• Before renovating or adding to a building with no reliable drawings
• When an architect or engineer needs existing floor plans, sections or elevations
• To record mechanical, electrical or structural elements before ceilings and walls are closed
• For as-built documentation of completed interiors or complex structures
• When a site has too much detail to measure efficiently point by point

Equipment and Methods

We use a handheld SLAM LiDAR scanner for walk-through capture. Where accurate positioning is required, the scan is tied to control points measured with robotic total stations and GPS/GNSS receivers. For open outdoor areas and stockpiles, drone surveying may be a better fit, available on request. For design-grade ground detail, we combine scanning with a topographic survey.

Deliverables

Deliverables are confirmed in the quotation and typically include:

• LAS point cloud of the scanned areas
• DWG drawings extracted from the point cloud, such as plans, sections or existing-conditions linework, where agreed

We also build BIM models in-house from our scan data through our in-house Scan-to-BIM modelling service, where agreed in the quotation.

Our Process

1. Tell us what you need. Send the project location, the area to be scanned and how the data will be used.
2. Agree the scope. We confirm coverage, control, deliverables, formats and the level of detail.
3. Scan. We capture the agreed areas, checking coverage on site.
4. Process. We register, clean and check the point cloud and prepare any drawings.
5. Deliver. You receive the LAS and DWG files, and we're available for follow-up questions.

LiDAR data supports as-built surveys, renovation design and construction layout on existing buildings.
