The radians value returned from the math.atan () function can be converted into degrees using another function named math.degree 4.7. atan () Returns the arc tangent of the argument received: Math.atan (1); // returns pi/4 The result is an angle in the range pi /2 to pi /2. It sounds like you're using Java, so I would recommend looking into something like GDAL. This uses the haversine formula to calculate the great-circle distance between two points that is, the shortest distance over the earths surface giving an as-the-crow-flies distance between the points (ignoring any hills they fly over, of course! Building Spark Contributing to Spark Third Party Projects. Math.sin() Math.sin(x) x -1 1 Angle in radians = Angle in degrees x PI / 180.
