Texas Public Radio reports on how drones can be used for geographical research. "For years, commercial drones have improved with better battery life, stronger motors, lower cost and are easier to use. Researchers are increasingly turning to drones to collect data they couldn’t before, including biologists using them to count trees and officials to monitor snow depth.
