Restriction zones are no-fly zones that can be created during mission planning to define an obstacle that the flight path will navigate around, including when resuming a mission. This is critical for safer inspections or reality modeling missions, or mapping around known obstacles.
Restriction zones support the following components. More examples below.
- Facade (Horizontal and Vertical)
- Map (Including terrain follow)
Restriction Zones have the following main settings:
- Circle and Polygon Shape
- Min and Max Altitude
When using restriction zones, it is important to use 3D previews to visually inspect the flight path behavior navigating around the restriction zone, including testing resuming behavior.
Learn how to create and setup a restriction zone and view examples for various component types and use cases.
Creating and Using Restriction Zones
Step 1 - On a Plan, Right Click on Map to Create Restriction Zone
We are going to add a restriction zone for this map, since part of the construction is now going vertical and a crane is operating in the suggested restriction zone.
A new default circle restriction zone will be created and restriction zone settings menu will open where you can change the shape, and set altitudes.
Step 2 - Adjust the Shape and Position
Drag the boundary points, or add new ones when setting up a polygon, to adjust the shape to match the restricted area.
Select the center of the restriction zone to move it.
Step 3 - Adjust the Altitude
Adjust the max altitude to the height of the obstacle.
As you can see above, the flight path is still going through the restriction zone, this is because the map altitude is above the restriction zone max altitude.
By increasing the max altitude of the restriction zone above the map altitude, we can see that the path no longer enters the restriction zone.
Step 4 - Use the Simulated Drone to Review Flight Path
Open the simulated drone by right clicking on the map, and selecting Simulated Drone.
Move the simulated drone around the map, by both dragging around the simulated drone on the map, or dragging (left click drag), rotating (right click drag) and zooming on the drone preview window.
Notice the flight path behavior around the restriction zone from various perspectives.
Step 5 - Check Resuming Behavior Using the Simulator
Open the Simulator from the Plan Menu
Run the mission and pause it in an area near the restriction zone. The map will show the purple pause location.
Move the simulated drone to a different side of the restriction zone (such as where you will perform a battery swap), and select Start to view the purple resume path, or open to view the resuming mission.
See the purple resume path route around the restriction zone.
Facade Inspections Using Multiple Restriction Zones
It is possible to create multiple restriction zones at various altitudes to define more complex inspection areas. In this example we have an oil and gas tank inspection using the facade component with individual tanks and pipes marked as restriction zones.
Tower Inspection with Spiral
In this example we are performing a spiral tower scan using the Facade component and marking both the tower and nearby structure as restriction zones.
