Optical Monitoring
Above: Imetrum’s portable, long-range, camera-based monitoring system was used in the benchmarking trial. How reliable are optical monitoring techniques for civil engineering structures? Editor’s Note: Camera-based systems have long been used in industrial metrology for manufacturing, materials testing, and integrity monitoring. Now they’re finding utility in the “macro” realms of AEC (architecture, engineering, and construction). Many people in the...
How FAA Exemptions Work for Commercial Operation of sUAS
How They Work for Commercial Operation of sUAS On February 15, 2015, the Federal Aviation Administration (FAA) published a Notice of Proposed Rulemaking, which proposes to enact part 107 of the Code of Federal Regulations. Specifically, the rulemaking proposes operating requirements to allow small unmanned aircraft systems (sUAS) to operate for non-hobby or non-recreational purposes....

The Two Fences
Surveyor Igor Kidinsky, alias Eager (The Kid), could not seem to fit the fence with his calculated property corner. His calculations kept leading him to the other fence, a few feet away. Glenny Dale, alias Glutton (The Old Man), looked on, struggling to convince his logical mind that there should be two fence lines here...
Autodesk + Leica Geosystems
Two tech giants embark on a collaboration and education outreach. At June 2015’s HxGN LIVE (the annual user conference for Leica Geosystems and other divisions of Hexagon), we spied something rather surprising: an Autodesk booth. What’s more, someone at the booth was using Autodesk software for construction layout on a consumer tablet, driving a Leica...
Quantum Navigation

Many of the most accurate measurement devices, including atomic clocks, work by observing how atoms transfer between individual quantum states. The longer the atomic transition can be observed, the more precisely it...
