Intersection of 2 Circles

Calculate and map the intersection points of two geodesic circles.

Calculate the intersection of 2 circles and display the results on a map. This is trilateration from two distance measurements. Enter the center coordinates and radius for each circle, then press Calculate. Coordinate inputs accept DDM, DD, and DMS formats. If the circles do not intersect because the measured distances are a little off, the best fit option finds the point that comes closest to both circles.
