  1. Step 1

    Polygon area and perimeter on the ellipsoid

    The area and perimeter of the site.

    You should see The area is 0.299779355 km², with a perimeter of 2.199 km.

    Open with these values

  2. Step 2

    Survey grid (lawnmower pattern)

    Flight lines 60 m apart at 80 m and 8 m/s: path length and flight time.

    You should see Fly 10 lines for 8.85 km and about 154 photos. That takes about 18.4 min.

    Open with these values

  3. Step 3

    Battery energy (mAh to Wh)

    The energy in one battery pack.

    You should see The pack holds 313.4 Wh, with 313.4 Wh usable.

    Open with these values

  4. Step 4

    Drone flight time

    Flight time per pack at a power draw of 900 W, keeping 20% in reserve.

    Carries battery energy from step 3.

    You should see Hover time is about 16.7 min.

  5. Step 5

    ASPRS accuracy (Edition 2)

    The accuracy class your checkpoints support, to the ASPRS standard.

    You should see Vertical accuracy is 4.47 cm RMSE. The checkpoint count meets the Edition 2 minimum of 30.
