3.4 Best Practices for Missions
Sentera provides
several scenarios that will aid you in setting up to collect imagery to get the intended results. The examples are intended to be a starting point. Many users have found it helpful to fine-tune these settings based on variables, such as crop, time of year, location. contact Support at Sentera to assist with resetting the password and provide a login email address. For assistances, contact Sentera Support at 1-844-SENTERA/612-244-2000, or
support@sentera.com.
3.4.1 Scenarios
The following are several scenarios you can use to set up your mission.
NDVI/NDRE and/or RGB QuickTiles
For overall ideal settings:

Overlap
| 30% or Early Scout or Late Scout setting in FieldAgent Mobile.
|
Altitude
| 200/400 feet or 61/122 meters
|
Speed
| 20 MPH or 8 m/s
|
Time of Day
| Mid-Day. You want to fly when the sun is highest in the sky.
|
Conditions
| Clear, Mostly Clear, or Overcast
|
NDVI/NDRE and/or RGB Full Mosaics
For overall ideal settings:

Overlap
| 80% or Early Map or Late Map setting in FieldAgent Mobile.
| |
Altitude
| 200/400 feet or 61/122 meters
| |
Speed
| 20 MPH or 8 m/s
| |
Time of Day
| Mid-Day. You want to fly when the sun is highest in the sky.
| |
Conditions
| Clear, Mostly Clear, or Overcast |
3D Mapping or Volumetric
For overall ideal settings:

Overlap
| 80% or Early Map or Late Map setting in FieldAgent Mobile.
|
Altitude
| 200/400 feet or 61/122 meters
|
Speed
| 12 MPH or 5 m/s (200 feet), 18 MPH or 8 m/s (40 feet)
|
Flight Pattern
| Best results will require that the location to be flown twice; once in a North-South pattern, and once in an East-West pattern.
|
Time of Day
| Mid-Day. You want to fly when the sun is highest in the sky.
|
Conditions
| Clear, Mostly Clear, or Overcast
|
Stand Count
For overall ideal settings:

Overlap
| 300% or Stand
|
Altitude
| 50 feet or 16 meters
|
Speed
| 10 MPH or 5 m/s
|
Weed Density Maps
For overall ideal settings:

Overlap
| 30% or Weed
|
Altitude
| 150 feet or 45 meters
|
Speed
| 15 MPH or 7 m/s
|
Small Fields or Plots
For overall ideal settings:

Overlap
| 30% to 80%
|
Altitude
| 51 to 400 feet or 16 to 122 meters
|
Speed
| 1-18 MPH or 1-8 m/s
|
Time of Day
| Mid-Day. You want to fly when the sun is highest in the sky.
|
Conditions
| Clear, Mostly Clear, or Overcast
|
Notes: Small plots can be challenging to fly; the main thought is to test different options until you find what works for you. Advanced users can change how and when the sensor is triggered for collecting very small plots. This does require manual flight in most cases.3.4.2 Consider Wind and Field Shapes
When setting up your mission, take several things into account:
· Wind: If the wind is strong and close to, but not above, the aircraft's limits to obtain high-quality imagery, it is recommended that you should fly at a slower speed, for example in the 4 to 5-meter range. This will increase flight time and the number of batteries needed to complete the flight. In addition, the pilot may want to consider adjusting the aircraft's flight directly so that the aircraft is flying into and with the wind. This will help keep it on the path.
· Field Shape: Adjusting the flight path can make the collection of the images more efficient and may have a reduction in flight time. Shown in figure 43 are two different flight patterns of the same field. The flight pattern for North-South will produce a better QuickTile image as there are fewer stops and starts of the drone changing direction.
Figure 43: Flight Patterns
