English(EN) Why a Distance Calculation From GPS Coordinates Was Wrong by 20%

由于经纬度度数差异，GPS距离计算常出错

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-12 22:51

在计算GPS坐标之间的距离时，一个常见的错误是将经度度数视为与纬度度数等同。虽然一度纬度大约固定为111,320米，但一度经度的距离会随着纬度的增加而缩小，在北纬51.5°时约为69,290米。如果不考虑这种差异，根据航向的不同，距离计算可能会长达61%。另一个错误原因是使用了Web Mercator投影，该投影也会根据纬度因素夸大距离。 AI
