A Dam Good Mix
Above: A view of the Brighton Dam in Brookeville, Maryland, from one of the project’s UAVs. Combining UAVs and 3D computer vision can make infrastructure inspections cost-effective. More than 70% of the 90,000 dams scattered across the U.S. are, according to the American Society of Civil Engineers (ASCE), half a century old. The age of dams,...
3D Evidence
Diagram software helps the New Mexico State Police enhance their extensive forensics work. Reconstructing what happened at the scene of a traffic accident or a crime is a complex undertaking involving scientific methods, physical evidence, deductive reasoning—and their interrelationships. It also requires hardware to gather data and software to analyze it and display it. Laser...
Clear Scanning on the Clearwater
Above: The survey included collecting bathymetric data on the river bottom and bridge substructure with multibeam sonar as well as capturing above- and below-waterline mobile mapping data with the Leica Pegasus: Two mobile sensor platform. Two well-paired engineering firms used high-accuracy mobile mapping to combine bathymetry and lidar data for a fast-turnaround topographic survey of...
6D SLAM
An indoor spatial intelligence start-up from Germany is pushing the BIM industry forward through a combo of navigation and visualization. The line of people at the Intergeo Trade Fair in Frankfurt, Germany, waiting to get their hands on the NavVis M6 was long. Where everyone was on the lookout for the latest geospatial products on...
Walkaround Mobile Scanning Part 1
Above: Walkaround mobile scanning is being increasingly used as a go-to tool for as-built surveys of residential properties as an input to remodel design. Credit: Precision Property Measurements. Part 1: Basic types, differences, and advantages. Walkaround mobile scanning includes “backpack,” “push-cart,” “hand-carry,” and “handheld,” but whatever you call it, it’s gaining real momentum in the...

BLK2GO SLAM (simultaneous localization and mapping) lidar handhelds have become popular for BIM, as-builts, and rapid 3D modeling. The new Leica Geosystems BLK2GO shares some of the core technologies of earlier members of the BLK family (like the BLK360 scanner). What distinguishes this from many of the other SLAM handhelds is that it utilizes cameras...
