Why geofencing is required in Drone Programming - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a geofence boundary for the drone.

Drone Programming

geofence = {'latitude_min': 34.0, 'latitude_max': 35.0, 'longitude_min': [1], 'longitude_max': -118.0}

Drag options to blanks, or click blank then click option'

A-119.0

B-120.0

C-116.0

D-117.0

💡 Hint

Common Mistakes

Using a longitude_min greater than longitude_max causing invalid geofence.

The longitude_min must be less than longitude_max to define a valid geofence boundary.

2fill in blank

medium

Complete the code to check if the drone is inside the geofence.

Drone Programming

if geofence['latitude_min'] <= drone_latitude <= geofence['latitude_max'] and drone_longitude [1] geofence['longitude_min'] and drone_longitude <= geofence['longitude_max']:
    status = 'inside'
else:
    status = 'outside'

💡 Hint

Common Mistakes

Using '<' instead of '>=' causing incorrect boundary check.

The drone longitude must be greater than or equal to longitude_min to be inside the geofence.

3fill in blank

hard

Fix the error in the code to prevent the drone from flying outside the geofence.

Drone Programming

def enforce_geofence(drone_latitude, drone_longitude):
    if not (geofence['latitude_min'] <= drone_latitude <= geofence['latitude_max'] and drone_longitude >= geofence['longitude_min'] and drone_longitude <= [1]):
        return 'Return to base'
    return 'Continue mission'

Cgeofence['latitude_min']

Dgeofence['longitude_max']

💡 Hint

Common Mistakes

Using latitude values instead of longitude for longitude boundary check.

The longitude upper boundary must be geofence['longitude_max'] to correctly check the geofence limit.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps drone IDs to their geofence status.

Drone Programming

status_map = {drone_id: 'inside' if ([1]) else 'outside' for drone_id, (lat, lon) in drone_positions.items() if lat [2] geofence['latitude_min']}

Drag options to blanks, or click blank then click option'

Ageofence['latitude_min'] <= lat <= geofence['latitude_max'] and geofence['longitude_min'] <= lon <= geofence['longitude_max']

Blat > geofence['latitude_max']

D>

💡 Hint

Common Mistakes

Using incorrect comparison operators causing wrong filtering or status assignment.

The first blank checks if the drone is inside the geofence. The second blank ensures latitude is less than or equal to the minimum latitude for filtering.

5fill in blank

hard

Fill all three blanks to create a function that returns drones outside the geofence.

Drone Programming

def drones_outside_geofence(drones):
    return {drone_id: (lat, lon) for drone_id, (lat, lon) in drones.items() if lat [1] geofence['latitude_min'] or lat [2] geofence['latitude_max'] or lon < geofence['longitude_min'] or lon [3] geofence['longitude_max']}

Drag options to blanks, or click blank then click option'

D<=

Attempts:

💡 Hint

Common Mistakes

Using wrong comparison operators causing incorrect detection of outside drones.

The function checks if latitude is less than minimum or greater than maximum, or longitude is less than minimum or greater than maximum to find drones outside the geofence.
