Study Notes

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

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

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.

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 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:
- 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: 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.
