//Latitude (horizonal), longitude(vertical) so |

// 1 degree latitude is ~ 111320 meters, since the distance between the horizonal lines is always the same |

|
// 1 degree longitude is ~111320 meters at equator but gets shorter as we get closer to the poles. |

// so 1 degree longitude is 64.5 km at denmarks southern point (gedser=54.55,11.95) |
