GPS data processing in Drone Programming - Mini Project: Build & Apply

GPS Data Processing for Drone Flight

📖 Scenario: You are programming a drone that collects GPS coordinates during its flight. The drone records latitude and longitude points as it moves. You want to process this GPS data to find which points are within a certain distance from the starting location.

🎯 Goal: Build a program that stores GPS points, sets a distance threshold, filters points within that distance from the start, and then displays those points.

📋 What You'll Learn

Create a list of GPS points with exact latitude and longitude values

Create a variable for the maximum distance threshold

Write code to filter GPS points within the threshold distance from the start point

Print the filtered GPS points

💡 Why This Matters

🌍 Real World

Drones collect GPS data to track their flight path and avoid obstacles. Processing GPS points helps in navigation and safety.

💼 Career

Understanding how to handle GPS data is important for drone programmers, GIS specialists, and developers working with location-based services.

1

Create the GPS points list

Create a list called gps_points with these exact tuples representing latitude and longitude: (34.05, -118.25), (34.10, -118.20), (34.00, -118.30), (33.95, -118.35), and (34.07, -118.22).

Drone Programming

# Create the gps_points list with given latitude and longitude tuples
# Your code here

Need a hint?

Use a list with tuples for each GPS point. Each tuple has two numbers: latitude and longitude.

2

Set the distance threshold

Create a variable called max_distance and set it to 0.07. This represents the maximum distance from the start point to keep.

Drone Programming

gps_points = [(34.05, -118.25), (34.10, -118.20), (34.00, -118.30), (33.95, -118.35), (34.07, -118.22)]
# Create max_distance variable and set it to 0.07
# Your code here

Need a hint?

This variable will help us decide which points are close enough to the start.

3

Filter GPS points within the distance

Create a list called close_points that contains only the points from gps_points whose latitude difference from the start point gps_points[0] is less than or equal to max_distance. Use a for loop with variable point to check each point.

Drone Programming

gps_points = [(34.05, -118.25), (34.10, -118.20), (34.00, -118.30), (33.95, -118.35), (34.07, -118.22)]
max_distance = 0.07
# Create close_points list with points close to gps_points[0] by latitude
# Your code here

Need a hint?

Compare the latitude (first number) of each point to the start point's latitude.

4

Display the filtered GPS points

Write a print statement to display the close_points list.

Drone Programming

gps_points = [(34.05, -118.25), (34.10, -118.20), (34.00, -118.30), (33.95, -118.35), (34.07, -118.22)]
max_distance = 0.07
close_points = []
for point in gps_points:
    if abs(point[0] - gps_points[0][0]) <= max_distance:
        close_points.append(point)
# Print the close_points list
# Your code here

Need a hint?

The output should show only the points close enough by latitude to the start point.
