    Study Notes

    Comprehensive Mapping Class

    • Today's mission involves:
      • Creating double grids with orbits of the whole area
      • Performing free flights of a building
      • Performing orbits of another building
      • Merging all data sets together
    • Due to tree coverage, a quad grid and orbits of the whole facility will be done
    • Minimum obstacle clearance altitude (MOCA) must be checked to ensure clearance by at least 25 ft

    Line of Sight and Tree Coverage

    • Main issue with trees and structures:
      • Losing line of sight
      • Running into them during flight
    • To counteract tree coverage:
      • Fly up higher and do it all in one grid
      • Use a higher altitude to maintain line of sight

    Mapping Area and Grid Setup

    • Mapping area: the whole property, from one street corner to another, including part of the church parking lot
    • Grid setup:
      • Double grid through Pix4D Capture
      • Use DJI Phantom 4 Advanced drone
      • Camera settings: Apple Maps, units in feet, upload resolution: no, auto download images: off
      • Drone speed: middle (not too slow, not too fast)
      • Angle of camera: 70°
      • Front overlap: 70°
      • Max speed on drone: fine as long as flying a Phantom

    Safety and Altitude

    • Safety checks:
      • Maintain line of sight
      • Watch out for hawks and pause mission if necessary
      • Turn into atti mode and descend if hawk is close
    • Determine altitude by flying to the furthest corner of the mapping area and checking visibility
    • Minimum altitude: 191 ft to maintain visual line of sight
    • Flights: two drones in the air at a time, one at 200 ft, one at 240 ft, with a separation of at least 40 ft

    Camera Settings and Picture Mode

    • Camera settings:
      • Angle of camera: 70°
      • Front overlap: 70°
      • White balance: sunny
    • Picture mode:
      • Safe mode recommended for Mavic 2 Pro
      • Safe mode adds time to the flight but prevents rolling shutter effect
      • Fast drone speed acceptable in safe mode

    Landing and Mission Completion

    • Landing: do not go straight down, landing mode engages at 300 feet
    • Mission completion:
      • Wait for checklist to complete
      • Hit start to begin the mission

    Comprehensive Mapping Mission

    • The mission involves creating double grids with orbits of the whole area, performing free flights of a building, performing orbits of another building, and merging all data sets together.

    Line of Sight and Tree Coverage

    • Tree coverage poses two main issues: losing line of sight and running into trees during flight.
    • To counteract tree coverage, flying higher and using a higher altitude to maintain line of sight is recommended.

    Mapping Area and Grid Setup

    • The mapping area covers the whole property, from one street corner to another, including part of the church parking lot.
    • Grid setup involves using a double grid through Pix4D Capture, a DJI Phantom 4 Advanced drone, and specific camera settings:
      • Apple Maps, units in feet, upload resolution: no, auto download images: off.
    • Drone settings:
      • Speed: middle (not too slow, not too fast).
      • Angle of camera: 70°.
      • Front overlap: 70°.

    Safety and Altitude

    • Safety checks include maintaining line of sight and watching out for hawks, with a plan to turn into atti mode and descend if necessary.
    • Determining altitude involves flying to the furthest corner of the mapping area and checking visibility.
    • Minimum altitude: 191 ft to maintain visual line of sight.
    • Flights: two drones in the air at a time, one at 200 ft, one at 240 ft, with a separation of at least 40 ft.

    Camera Settings and Picture Mode

    • Camera settings:
      • Angle of camera: 70°.
      • Front overlap: 70°.
      • White balance: sunny.
    • Picture mode:
      • Safe mode recommended for Mavic 2 Pro to prevent rolling shutter effect.
      • Safe mode adds time to the flight but allows for fast drone speed.

    Landing and Mission Completion

    • Landing: do not go straight down, as landing mode engages at 300 feet.
    • Mission completion involves waiting for the checklist to complete and hitting start to begin the mission.
