Ultra-Low Altitude Plant Sensing Through Unmanned Aerial Vehicles with Portable Hyperspectral Imagers for Detection of Glyphosate-Resistant and Susceptible Weeds in Soybean Fields Annual Report

Remote sensing technology on unmanned aerial vehicle (UAV) has a great potential for precision crop management with ultra-high spatial resolution (a few centimeters to millimeters per pixel) imagery through the flight at ultra-low altitudes (tens of meters to a few meters). Therefore, a portable hyperspectral sensor mounted on a small UAV has the potential to overfly a soybean field and quickly determine the distribution of weeds, including GR and GS weeds. This information can be provided in a timely manner for Mississippi soybean producers and consultants to improve their site-specific weed management.
