All Over the Map

The regulations and uses of UAVs for mapping in Latin America are as diverse as those cultures, but their drivers are much the same as we see here in the United States. Using manned airplanes for aerial photography and photogrammetry is an especially expensive proposition for countries south of the Rio Grande. The reasons are...

Aerial Imaging in Antarctica

It was quite an adventure: an all-or-nothing mission to map a research station in Antarctica. Like numerous countries around the world, Ecuador’s mapping agency, Instituto Geografico Militar (National Military Geographic Institute of Ecuador or IGM), is a technical institution within the country’s military establishment. The IGM is responsible for developing the national mapping and the geographic...

UAV News: Recent Court Cases

  Here are two recent court cases involving the Federal Aviation Administration (FAA) andusers of unmanned aerial vehicles (UAV). In both cases, the FAA’s position that their 2007 policy memorandum on UAVs, particularly in regard to their being used for commercial purposes, was found to be not legally binding. Rafael Pirker v. FAA In this court case,...

Drone Art: Art Meets the Science of UAS at Elevated Element

Our company, Elevated Element, uses UAS for aerial photography. Our monuments capture project came about when we were contacted by Direct Dimensions, a 3D modeling firm, with the idea of combining the techniques of aerial UAS photography and digital 3D scanning. We chose the Francis Scott Key Monument in Baltimore’s neighborhood of Bolton Hill because...

Accuracy With Small UAS Mapping

Two recent advances in heretofore unrelated technologies are giving birth to a new way to perform local-area metric mapping. The first is the development of small, unmanned aerial systems (sUAS), spurred on primarily by the miniaturization of autopilot components.  The second is the development of novel algorithms for creating digital surface models from collections of...

From Traditional Photogrammetry to UAS

Photogrammetry has changed substantially in the past three decades. When Jeff Yates began in the business 32 years ago, he used a projection system known as a Kelsh two-bucket plotter. “That was four generations ago of photogrammetric systems hardware,” he recalls. “From there, we went to the analog stereo plotter. That was the second big...
