Remote Sensing of Environmental Conditions

Remote Sensing of Environmental Conditions

Accurately measuring environmental conditions is critical for natural resource planning, estimation of agricultural conditions, weather forecasting and a number of essential scenarios affecting our everyday life. Emerging Science joins Christian Skalka, assistant professor of computer science at the University of Vermont, as he explains how scientific advances in gathering and transmitting environmental data are giving us a better understanding of ...

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 ...
