I am wanting to find the distance between two different points. This I know can be accomplished with the great circle distance. http://www.meridianworlddata.com/Distance-calculation.asp Once done, with a point and distance I would like to find the point that distance north, and that distance east in order to create a box around the point.

Here is a Java implementation of Haversine formula. I use this in a project to calculate distance in miles between lat/longs. public static double distFrom(double lat1, double lng1, double lat2, double lng2) { double earthRadius = 3958.75; // miles (or 6371.0 kilometers) double dLat = Math.toRadians(lat2-lat1); double dLng = Math.toRadians(lng2-lng1); double sindLat = Math.sin(dLat / 2); double sindLng = Math.sin(dLng / 2); double a = Math.pow(sindLat, 2) + Math.pow(sindLng, 2) * Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)); double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)); double dist = earthRadius * c; return dist; }
