Micro-Drones Moving into Commercial Operations

Micro-drones, those that weigh less than 250 grams, are popular with recreational UAV flyers for several reasons. They are relatively inexpensive, with models starting at under $500. Additionally, the 249-gram-and-under category requires no FAA registration, nor do they fall under the remote ID (RID) regulation. Now, with the aid of sophisticated flight planning and automated...

Fresh Specs That Are Lifting the UAV Game

The latest UAV technologies released in the first quarter of this year seem to be bucking the trend of white-washed main frames and disappearing control buttons commonly seen in the last five years. Instead, the current crop of drones is gaining more advanced robotic payloads, as well as imbibing unconventional shapes that allow for better...

3D Cities from a Single System

Above: This screenshot is of CityMapper output. A look at the hybrid airborne system that combines lidar with oblique and nadir imagery. Over the last five years I’ve built and used a lot of 3D GIS and BIM models. Almost all of this has required the capture of stereo imagery and oblique imagery and a...

Satellite Imagery’s Impact

Above: The highest resolution of commercial satellite imagery is still more than an order of magnitude lower than the highest resolution attainable from aerial platforms. Keystone Aerial Surveys, Inc. developed this digital surface model from 1.75 cm digital imagery taken with a low-altitude flight. The resolution is sufficiently high to enable its use for mapping...
