Setting geofence boundaries in Drone Programming - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a geofence in drone programming?

A geofence is a virtual boundary set around a specific geographic area to control where a drone can fly. It helps keep the drone within safe or legal zones.

Name two common shapes used to set geofence boundaries.

The two common shapes are circles (defined by a center point and radius) and polygons (defined by multiple points connected to form an area).

Why is it important to set altitude limits in geofence boundaries?

Altitude limits prevent drones from flying too high or too low, avoiding collisions with buildings, aircraft, or restricted airspace.

intermediate

How does a drone typically respond when it reaches a geofence boundary?

The drone can stop, hover, return home, or alert the operator to prevent crossing the boundary.

beginner

What data is needed to program a geofence boundary?

You need geographic coordinates (latitude and longitude) for the boundary points, altitude limits, and sometimes time or flight mode restrictions.

What does a geofence boundary do for a drone?

A Increases the drone's speed

B Limits where the drone can fly

C Changes the drone's camera angle

D Controls the drone's battery life

A geofence sets a virtual boundary to limit the drone's flying area.

Which shape is NOT commonly used for geofence boundaries?

A Square

B Polygon

C Circle

D Triangle

Squares are not typically used as a separate shape; polygons cover all multi-point shapes including triangles and squares.

What happens if a drone reaches the geofence limit?

A It ignores the boundary

B It speeds up

C It shuts down immediately

D It stops or returns home

Drones usually stop, hover, or return home to avoid crossing the geofence.

Which data is essential to define a geofence?

A Geographic coordinates

B Drone color

C Pilot's name

D Camera resolution

Geographic coordinates define the location of the geofence boundary.

Why set altitude limits in geofences?

A To save battery

B To increase flight speed

C To avoid collisions with other objects

D To improve video quality

Altitude limits help prevent collisions with buildings, aircraft, or restricted airspace.

Explain how to set a geofence boundary for a drone flight.

Think about the area, height, and what the drone should do when it reaches the edge.

Why are geofence boundaries important for drone safety?

Consider risks of flying without limits.
