Answers to Questions

How to find a GPS coordinate from a given address?

Use geocoding / geolocalisation function also available on dCode. It is not a calculation but of an association between an address and coordinates.

How to calculate a point at equal distance of 2 others?

dCode calculate the median point on a sphere with the same radius as Earth (it is not the same than on a plan).

Example: Consider the coordinates P1 (45.678 N, 5.4321 E) and P2 (46.810 N, 5.1015 E), the median point is located (46.2441 N, 5.2685 E), whereas on a 2D plane it would have been slightly shifted (46.2440 N, 5.2668 E).

How to calculate a finish point when having a starting point?

Knowing the direction and the distance on a sphere of radius R, dCode can calculate the path and find arrival coordinates.
