GPS coordinate system (latitude, longitude, altitude) in Drone Programming - Mini Project: Build & Apply

GPS Coordinate System (latitude, longitude, altitude)

📖 Scenario: You are programming a drone to record its GPS position. The drone uses three values: latitude, longitude, and altitude to know where it is in the sky.Latitude and longitude tell the drone where it is on the Earth's surface. Altitude tells how high it is above the ground.

🎯 Goal: You will create a program that stores a GPS coordinate with latitude, longitude, and altitude. Then you will set a limit for altitude, check if the drone is flying too high, and finally print a message with the drone's position and altitude status.

📋 What You'll Learn

Create a dictionary called gps_coordinate with keys 'latitude', 'longitude', and 'altitude' and exact values 37.7749, -122.4194, and 120 respectively.

Create a variable called max_altitude and set it to 100.

Create a variable called altitude_status that is 'Too High' if the altitude is greater than max_altitude, otherwise 'Safe'.

Print a message showing the latitude, longitude, altitude, and altitude status in this exact format: "Drone position: (37.7749, -122.4194), Altitude: 120m - Status: Too High".

💡 Why This Matters

🌍 Real World

Drones use GPS coordinates to navigate and maintain safe flying heights. This program helps monitor if the drone is flying within safe altitude limits.

💼 Career

Understanding GPS data and conditional checks is important for drone programming, robotics, and any job involving location tracking and safety monitoring.

1

Create the GPS coordinate dictionary

Create a dictionary called gps_coordinate with these exact entries: 'latitude': 37.7749, 'longitude': -122.4194, and 'altitude': 120.

Drone Programming

# Create the gps_coordinate dictionary with latitude, longitude, and altitude
# Your code here

Need a hint?

Use curly braces {} to create a dictionary. Put keys and values separated by colons.

2

Set the maximum allowed altitude

Create a variable called max_altitude and set it to 100.

Drone Programming

gps_coordinate = {'latitude': 37.7749, 'longitude': -122.4194, 'altitude': 120}
# Create max_altitude variable and set it to 100
# Your code here

Need a hint?

Just write the variable name, an equals sign, and the number 100.

3

Check if altitude is too high

Create a variable called altitude_status that is 'Too High' if gps_coordinate['altitude'] is greater than max_altitude, otherwise 'Safe'. Use a simple if-else statement.

Drone Programming

gps_coordinate = {'latitude': 37.7749, 'longitude': -122.4194, 'altitude': 120}
max_altitude = 100
# Create altitude_status variable using if-else to compare altitude and max_altitude
# Your code here

Need a hint?

Use if to check the altitude, then assign the correct string to altitude_status.

4

Print the drone position and altitude status

Write a print statement that shows the message: "Drone position: (37.7749, -122.4194), Altitude: 120m - Status: Too High" using the values from gps_coordinate and altitude_status. Use an f-string.

Drone Programming

gps_coordinate = {'latitude': 37.7749, 'longitude': -122.4194, 'altitude': 120}
max_altitude = 100
if gps_coordinate['altitude'] > max_altitude:
    altitude_status = 'Too High'
else:
    altitude_status = 'Safe'
# Print the drone position and altitude status using an f-string
# Your code here

Need a hint?

Use print(f"...") and insert the dictionary values and altitude_status inside curly braces.
