摘要

这篇短文描述了一种从测量导线(适当地简化为椭球)计算坐标的方法,而不需要通过地图网格进行繁琐的迭代计算。以-160 km导线为例,验证了该方法的有效性和准确性。这表明用户的效率提高了67%,并且最终的坐标与使用基于地图网格的方法计算的坐标在向东2毫米和向北3毫米范围内一致。

Short note: Traverse computation on the ellipsoid instead of on the map plane
This short note describes an approach to compute coordinates from a survey traverse (properly reduced to the ellipsoid) without the need for tedious iterative computations via the map grid. A numerical example of a -160 km traverse is used to illustrate the efficiency and accuracy of the proposed approach. This shows a 67 % improvement in efficiency for the user, and the final coordinates agree to within 2 mm in easting and 3 mm in northing with those computed using the map-grid-based approach.
