基于经纬度快速计算两点间距离及测量误差

Quickly Calculate the Distance between Two Points and Measurement Error Based on Latitude and Longitude

直接用经纬度计算两点间距离(弧长)和测量误差,减小了大地坐标转换成平面坐标的环节。文章通过推导经向所在纬度每一度弧长的公式,结合Excel电子表格,达到快速运算求取两点间距离(弧长)和测量误差的目的,计算简单方便,改进了运算方法。

Directly calculating the distance （arc length） between two points and measurement error by using latitude and longitude, can reduce the link that geodetic coordinates transform into plane coordinates. By deducing the formula of longitude at the arc length of each latitude degree, combining with Excel spreadsheet, can achieve the purpose of rapid operation obtaining the distance （ arc length） between two points and the measurement error. This make the calculation simple and convenient, and also improve the calculation method.
