In Australian feral pigs are an enormous problem so military grade drones are used to fly above the 500 metres altitude ceiling covering some serious ground and fly at night with thermal grade military cameras. The infrared camera lets them locate the invasive pest animals by their heat signature. The drone passes the vision in real-time to the ground control station, where it can be seen on computers and forwarded to the farmer’s mobile lap tops. Once the drone locates the pigs a ground team is dispatched to remove the pest pigs. The drone costs roughly $1000/hour and the flights are usually 4 hours. https://www.facebook.com/gogreen.pestcontrol.1
