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 ...

Aerial Photogrammetry with Hexakopter

Aerial Photogrammetry with Hexakopter

In short, we placed Ground Control Points (GCPs) around a man-made ponding area at roughly ten meter intervals (40 x 30 m in total area). The GCPs were shot in with a deferentially-corrected GPS (0.1 m horizontal and 0.2m vertical resolution) and with a Total Data Station (0.03m vertical and horizontal resolution). We then flew the Hexakopter at 40m above ...

Using Photogrammetry with Low Altitude Aerial Photographs

The first part of a tutorial on how to use Leica Photogrammetry Suite (LPS) to create Digital Terrain Models (DTMs) and photomosaics from very low altitude aerial photographs (such as those take from a kite (KAP), blimp (BAP), or MikroKopter (MAP). The second part of a tutorial on how to use Leica Photogrammetry Suite (LPS) to create Digital Terrain Models ...
