Calculate Distance Between GPS Coordinates on Android
Introduction & Importance
Calculating the distance between GPS coordinates on Android is crucial for various applications, such as navigation, route planning, and location-based services. This calculator helps you determine the distance between two points with ease.
How to Use This Calculator
- Enter the latitude and longitude of the first point.
- Enter the latitude and longitude of the second point.
- Click the “Calculate” button.
Formula & Methodology
The Haversine formula is used to calculate the distance between two points on the surface of a sphere given their longitudes and latitudes. The formula is as follows:
a = sin²(Δlat/2) + cos(lat1) * cos(lat2) * sin²(Δlon/2)
c = 2 * asin(sqrt(a))
d = R * c
Where R is the radius of the Earth (approximately 6,371 km).
Real-World Examples
Example 1: Calculate the distance between Google’s headquarters (37.4224° N, 122.0856° W) and Apple’s headquarters (37.7749° N, 122.4194° W).
Example 2: Calculate the distance between the Eiffel Tower (48.8583° N, 2.2923° E) and the Empire State Building (40.7484° N, 73.9857° W).
Example 3: Calculate the distance between the Great Wall of China (40.4319° N, 116.5667° E) and the Pyramids of Giza (29.9792° N, 31.1342° E).
