UTM投影坐标反算的迭代算法

摘要

UTM投影是常用的一种投影方法，本文根据UTM投影坐标正算公式，用简单迭代法进行UTM投影坐标反算，其效果与直接用反算公式相同。这种迭代算法理论和形式简单，便于理解与编程，避免了枯燥的反算公式的推导。可为实际应用提供参考。%UTM projection is a projection method is com-monly used, in this paper, based on UTM projection coordi-nates calculate formula, with simple iterative method for back calculation of UTM projection coordinates, the effect is the same as with back calculation formula directly. Theory and form of this iterative algorithm is simple, easy to understand and pro-gramming, avoids the boring back calculation formula is de-rived. Can provide a reference for practical application.
