Virginia Tech has another tool in its arsenal for managing land resources that can be used to do everything from inventorying forests and identifying land-use changes to assessing soil erosion and water runoff on agriculture lands.
What is this powerful tool? A 1.5-pound unmanned aircraft, or drone.
“Our drone, a fixed-wing eBee, carried two different sensors — true color and infrared — that gathered land-use and land-cover data to support inventory mapping,” said John McGee, professor and Virginia Cooperative Extension geospatial specialist in Virginia Tech’s College of Natural Resources and Environment.
The eBee’s sensors capture data that will enable researchers to measure vegetative vigor — places in which chlorophyll activity differs drastically across the terrain. If the ground vegetation is stressed in a confined area, it might indicate that a structure, perhaps a foundation, is buried underground.
