Deducing from geodetic coordinate differential formula
Xiaohua Wang · Journal of Henan Polytechnic University · 2006
Based on the relation of function between e and a,geodetic coordinate differential formula is further deduced in detail and a new kind of geodetic coordinate differential formula is obtained in the paper.By comparing formula,computing and analyzing the difference of coordinate transformation,the conclusions are gained:very minute interval between them in small scope,but the new formula is a useful tool to get high precise coordinate transformation of GPS measuring point in large scope.
