approximate coordinates

基本解釋

We derived an approximate algorithm from geocentric to geodetic coordinates. The algorithm is very simple, but its accuracy can satisfied general geo-science research.
給出了一種由地心坐標(biāo)到大地坐標(biāo)的近似算法，這種算法非常簡單，但它的精度可以滿足一般地學(xué)研究的需要。

在確定地震工區(qū)位置時(shí)，用鼠標(biāo)在計(jì)算機(jī)屏幕上點(diǎn)出的矩形頂點(diǎn)只是近似值，需要根據(jù)這些近似值求出工區(qū)矩形頂點(diǎn)的精確值。
Analysis and examples show that using this method to estimate the approximate coordinates, the accuracy is obviously improved comparing with the approximate coordinates provided by GPS.
