Photogrammetry With a UAV

Photogrammetry With a UAV

This video demonstrate how UAV’s carrying photogrammetry payloads can be used in the industry. The data you see in this video was gathered using “DINGO” a VTOL UAV designed by the author. You can also see footage of a smaller variant which will be replacing it. This kind of data can also be gathered on larger areas, with increased precision, ...

Photogrammetry: Which is better, grid flight or ROI?

Photogrammetry: Which is better, grid flight or ROI?

“At our most recent sUAS mission we utilized the Mission Planner ROI (Region of Interest) feature to capture aerial images of the subject. The ROI datum allows the user to create a fixed centroid position to orient the camera and figure an equal distance from a point for the flight path. Our goal was to solve some of the distortion ...

Light Detection and Ranging (LiDAR) Returns

Light Detection and Ranging (LiDAR) Returns

This animation demonstrates how a discrete return LIDAR system records information as light travels through an object, like a tree. The NEON project will collected and offer free discrete return and full waveform LiDAR data for 30 years across it’s field sites. It will also offer derived data products like canopy height models and elevation data.

PHOTOGRAMMETRY: Eyes in the Sky

PHOTOGRAMMETRY: Eyes in the Sky

When Hurricane Irene hit North Carolina, the Photogrammetry Unit of the N.C. Department of Transportation knew it would be called into action. When the storm passed, the Photogrammetry Unit took to the skies from Raleigh-Durham International Airport in a Beechcraft C-90 aircraft mounted with a high-resolution digital camera. The group has flown missions at about 7,500 feet from Ocracoke to ...
