// 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) |
|
|
// and is 59.4km at northern point (skagen = 57.75,10.65) |
