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,...
Outstanding Geospatial Trends at INTERGEO 2019
INTERGEO, the world’s largest summit in positioning and geospatial tech, wrapped up last week in Stuttgart, Germany, proving that even after 25 years it still can be a great show. It’s the biggest geospatial event of the year where companies around the world showcase their current innovations for the industry, and the xyHt team was...
Navigating Streets with No Name
Where streets have no names, confusion creates geo biz opportunities. Those of us in the business of mapping take pride in our wayfinding skills. Yet, on a recent trip to Florence, I found myself searching aimlessly for my hotel in the city’s medieval street layout. Something was definitely wrong when I ended up between numbers...
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...
Caretographic Representations
In parts of the world where both man-made and natural catastrophes frequently occur, how are geospatial technologies being used? And for those of us whose jobs are to create maps of construction sites and other built-up areas, how can we responsibly use the same technology to monitor destruction and wreckage? I pondered these tough questions...
Piping Hot Tech
Above: The cramped field conditions in the underground tunnels are evident in this point cloud Trammel used to create the 3D tunnel piping. From crowded boiler rooms to hard-to-reach underground tunnels, BIM experts tell us how following a smooth workflow is key to rapidly creating accurate 3D pipe models from point clouds. Inside the Student...
