HDS Fundamentals
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
Safety
