Hi! I'm looking for the same answer and I wrote this code, in C: const double R_TERRA = 6378137; struct node { float latitude; float longitude; }; void mercatorSphericalToLatLon(long mercX, long mercY, struct node *point) { double lon = (mercX / 100.0) / (M_PI * R_TERRA) * 180.0; double lat = (mercY / 100.0) / (M_PI * R_TERRA) * 180.0; lat = 180.0 / M_PI * (2.0 * atan(exp(lat * M_PI / 180.0)) - M_PI / 2.0); point->longitude = (float)lon; point->latitude = (float)lat; }
