The Agras T-Series are Agricultural drones used for spraying your crops and fields. You can use one of  these drones along with a Phantom series drone, for instance, a Phantom 4 RTK for a complete agricultural solution. A typical workflow would look like: Plan a survey flight with the Phantom RTK for precise data collection that will be fed into the DJI Terra software to generate real-time mapping 2D/3D modeling and AI operation planning. Then using DJI Agricultural Management Platform, you plan for a Agras T-Series drone flight to spray your designated crop area. A one year Agricultural version license for DJI Terra software is available for free with the purchase of any of the DJI Agras T-Series drones. The DJI SmartFarm App delivers service and support for spraying and spreading campaigns. It can display data, allow for device management, field sharing, tutorials, collaboration for teams and measurement tools. You can control and manage your Agras drone and view the data on the drone as well.
