What is High-Definition Surveying?Laser Scanners Producing Rich Point Cloud Data

Laser Scanning• 3D data capture• Fast, accurate, complete, remote• Full panoramic, full colour• Compatible with TPS/GPS

From Realityto 3D Data

Point Clouds• Remote visualisation• x,y,z engineering measurements• 3D CAD and 2D drawing extraction• Data analysis (volume, clash, etc)

Primary differentiating feature: high density “as-built” or “as-is”

geometric data

The data is so dense, you get the The data is so dense, you get the added value of an added value of an imageimage

When does this technology make sense to deploy?

When it costs less than conventional

When it costs the same as conventional, but can provide meaningful “added-value”

Better quality, more complete data

Potential re-use/multi-use of data

Fuzzy scope, expected scope changes

Need to minimize schedule and construction risk

Faster project turnaround

Traceability
