Calculate Distance Using Latitude and Longitude in Android
Calculating distance using latitude and longitude in Android is crucial for various applications, such as navigation, route planning, and location-based services.
- Enter the latitude and longitude of the first location.
- Enter the latitude and longitude of the second location.
- Click the ‘Calculate’ button.
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 Δlat and Δlon are the differences between the latitudes and longitudes of the two points, R is the radius of the Earth, and d is the distance between the two points.
Real-World Examples
Let’s calculate the distance between three pairs of locations:
- New York, USA (40.7128° N, 74.0060° W) and London, UK (51.5074° N, 0.1278° W)
- Sydney, Australia (33.8688° S, 151.2093° E) and Tokyo, Japan (35.6895° N, 139.6920° E)
- Cairo, Egypt (30.0571° N, 31.2431° E) and Cape Town, South Africa (33.9249° S, 18.4241° E)
