What is the distance from one confluence point to the next ?
Well, it depends a little. If you want to reach the next confluence point to the north or to the south, the distance is always the same, or it would be if the Earth were a perfect sphere: it varies only from 110.57km (68.71mi) at the equator to 111.69km (69.40mi) between 89 degrees latitude and the poles. If you want to reach the next confluence point to the east or west, the distance depends on how far north or south you are. The distance is 111.32km (69.17 miles) at the equator, and decreases with increasing latitude. In other words, the closer to the poles you are, the nearer the next confluence point to the east/west becomes. At 89 degrees latitude, you can encounter a confluence point every 1.95km (1.21 miles) going east or west. (This is the reason for the Poles Problem) To compute the distance in east/west direction, given latitude, the following formula can be used: Distance in kilometers: 111.32 * cos(Latitude) Distance in miles: 69.17 * cos(Latitude) (Calculator should be set
