Here’s a slice of life from the western edge of the Eastern Plains of Colorado. As I write this, the Fourth of July is tomorrow, and I’m shopping for our holiday “staycation.” BBQ pulled pork, buns, baked beans, corn on the cob, and “tater salad.” Check. Should I pick up some fireworks? The informational sign […]

NASA’s Awesome Long-endurance VTOL UAS

The wizards at NASA’s Langley Research Center took a look at the current state of UAS and found two big problems: The flight time and range of electric multicopters is too short, and many fixed-wing UAS require extensive ground support for launch and recovery. With these challenges in mind, the team came up with two […]

As part of a bachelor’s thesis project, a university student successfully scanned more than 21,000 sq ft of complex office space in just 40 minutes with a mobile 3D laser scanner (the GeoSLAM ZEB-REVO), despite having never previously used the device. The point cloud created from the first-time scanning work was sufficient to generate an […]

This entry is part 4 of 49 in the series Pangaea

To round up this short series on low-cost approaches to aerial archeology surveying, we’ll look at an even lower-cost sensor technology that can be used in certain types of archeological projects. In the first part of this series we talked about how new, affordable multispectral sensors are being used with (relatively) inexpensive UAS to find […]

Swords into Plowshares: AUVSI XPONENTIAL 2018

This entry is part 5 of 49 in the series Pangaea

The last time I visited the AUVSI conference was about 10 years ago. I remember walking into the show and thinking, “Did I just accidentally walk onto a military base?” The exhibits were populated with Predators, Reapers, and at least one Global Hawk. Every other attendee was dressed in their best camo BDUs. Not judging, […]

Last February we took a look at how airborne lidar is revolutionizing the science of archeology in Lidar and The Lost City of the Monkey God. Lidar is nothing less than a godsend for the search for lost cities and civilizations. But it comes at a price, one that cash-strapped archeologists can’t always afford. I’d […]
