The GLS-2200 is a terrestrial 3D laser scanner designed for the construction surveyor — not the reality-capture specialist. Where general-purpose scanners prioritize raw point density and rely on office software for georeferencing, the GLS-2200 embeds survey-grade positioning workflows directly on the instrument: resection, backsight bearing, and known-point setup are selectable from the 3.5″ touchscreen, the same way a total station operator establishes a station. This means the point cloud is tied to site control coordinates as it is captured, not aligned days later in the office.

What distinguishes the three range variants?

The GLS-2200S (130 m at 90% reflectivity) covers interior spaces, building facades, and small civil sites. The GLS-2200M (350 m) handles road corridors, bridges, and mid-scale earthmoving. The GLS-2200L (500 m) is for open-pit mines, quarries, and large topographic surveys where scan station count is the primary cost driver and longer range directly reduces the number of setups. All three share the same 1.0 mm surface accuracy, 3.1 mm distance accuracy, and 6″ angular accuracy — the only variable is how far the laser can reach on a given surface. On low-reflectivity surfaces (9%), all three models are limited to 40 m, so the range advantage of the M and L only applies where surfaces are reasonably reflective.

How does the GLS-2200 fit a surveyor's existing workflow?

Unlike scanners that require the operator to learn a new software paradigm, the GLS-2200 runs the same resection and backsight routines familiar from TOPCON total stations. It can sight a prism target at up to 200 m to establish its position relative to site control, then scan with the coordinate system already resolved. The dual-camera system — a 170° wide-angle for scene context and an 8.9° coaxial telephoto for long-range target identification — captures HDR imagery that is mapped onto the point cloud for visual inspection and deliverable generation. Data exports to MAGNET Collage and standard BIM formats (including IFC and RCP) for integration with Autodesk and Bentley workflows.
