degree of latitude的意思|示意

One degree of latitude on the earth's surface equals almost 70 miles.

If they kept on going, and the next night they saw the pair of stars setting separately, then they would know that they were at a different degree of latitude.

如果他们继续走，第二天晚上看见这两颗星星分别落下，就知道他们在不同的纬度上了。

When working with data in geographic coordinates, this is a problem because the linear distance of a degree of latitude varies.

这样在处理地理坐标下的数据的时候就出现问题，原因是水平距离单位为经纬度。
