Moments later it plummeted into a ravine along with several other vehicles as the bridge collapsed beneath them....

The Future of Aerial Photogrammetry

Rapid advances in technology are changing the way we map from the air, but the 100-year-old technology of mapping by crewed airplanes will continue to fly into the future For thousands of years cartographers made maps using tools that mostly measured angles and distances, allowing for positioning of fixed objects over unknown topography. The earliest...

Sponsored Content: Revolutionizing Utility Mapping in North America

As many of you already know, inaccurate utility locational data is one of the main causes of utility strikes. In 2021, this has led to an estimated $30 billion societal cost due to delays and damages in the USA alone, according to The 2021 Damage Information Reporting Tool (DIRT) Report released in October by the...

Safety is Paramount in Aerial Drone Mapping

As the Federal Aviation Administration (FAA) prepares to release its ruling covering uncrewed aircraft flights beyond visual line of sight (BVLOS) in the National Airspace (NAS) the entire industry is holding its breath preparing for a new era of certainty and expansion.  Aerial photogrammetry will be one of the immediate beneficiaries of this new policy...

Built for Danger

While the operator stays safe, indoor drones carrying lidar and SLAM technology create a 3D map of the inside of hazardous spaces Nuclear power plants, ballast tanks, underground mines, toxic chemical plants, sewers, offshore oil storage, decommissioned industrial facilities—none of these are places suitable for humans; yet monitoring and inspection of the interiors are often...
