3D Laser Scanning (HDS)
Equipment
Software
– Leica Cyclone
– Cyclone 2 Topo (Virtual Surveyor)
– Cloudworx for AutoCAD or Microstation
Hardware
– Leica HDS 3000 Laser Scanner
– Laptop computer
– Honda Generator or other 110v Power Supply
Benefits of HDS
Virtually obtain bridge structure measurements
Significant cost savings. Reduce or eliminate traffic control costs
No return visits – virtually survey any item on bridge structure
Unprecedented level of detail ie. Bolt patterns, cracks in concrete abutments, lane lines etc.
Applications for HDS
Civil:
Bridge Structure Mapping
Topographic Mapping
Construction As-Builts
Historic Preservation Surveying

Hydrographic Surveying
• What is it ?
– “Hydrographic Surveying” is the process of
collecting positional and depth information in
order to accurately chart lake/channel bottom
conditions.
– “Bathymetry” is the measurement of the
water’s depth
• It is the marine equivalent of a “Topographic” or
“Topo” map
