Distance from point to location on android?

Question

Java

Hello! There are gps coordinates of one place. You need to know the coordinates of the location AND calculate the distances from the location to that point. How can I do that? Is there some kind of library?

Answer 1

Here you don’t need to look for libraries, but remember geometry, and specifically the topic about vectors. Remember / look for how to get a vector from two points and then find out the length of this vector, this will be the distance. The formulas are very simple.

Answer 2

The formulas are given here www.movable-type.co.uk/scripts/latlong.html
You just have to decide in which system to count Rhumb line or Great circle.
