(c) Describe how the data from the drone is used by the farmer on the tablet. [2]

Answer

Answer Details

(a) Two advantages of using a tablet in the field rather than a desktop:

The tablet is lightweight and portable, so the farmer can carry it while walking through the fields, checking data and making decisions on the spot. [1]
The tablet has a touchscreen that can be operated easily outdoors (including while wearing gloves), without needing a separate keyboard, mouse or desk. [1]

(b) Two tasks the drone's embedded computer performs:

It controls the drone's flight path using pre-programmed GPS coordinates or real-time instructions from the controller, maintaining stable flight. [1]
It processes data from the on-board camera sensor to capture aerial photographs and video of the crops at the correct times and positions. [1]

(c) How the drone data is used on the tablet:

The aerial images captured by the drone are transferred wirelessly (via Wi-Fi or a mobile connection) to the farmer's tablet for viewing. [1]
The farmer can examine the images or use a specialised agriculture app to identify areas where crops are stressed, diseased, dry or in need of attention, allowing targeted treatment rather than treating the entire field. [1]
