"AeroVironment is emphasizing the drone’s ease of use: the operator plans a mission withthe tablet by tracing his finger over a map. The system guides the operator through a simple pre-flight check. The operator then presses the “fly” button, and the drone autonomously takes off, flies the mission and lands.
The Quantix carries color and multispectral sensors. AeroVironment says the DSS uses proprietary algorithms to produce high-resolution datasets and analyses of crops, bridges, roads, railways, pipelines and other assets."

so now you don't even need to know how to fly.
