要转换地球纬度经度(公里) [英] Want to convert the earth latitude & longitude in kilometer

问题描述

您好，我在C#中创建了简单的GPS应用程序，但是我想转换以千米为单位的地球经度，我有相应的公式，所以我不确定该公式给出的计算是否正确.因为这个公式在VB中

xtmp0 =(((69.172 * Cos(0))* 1.609344)* Val(经度)
ytmp0 =((((68.703 * Val(纬度)))* 1.609344)
请建议我是否正确的公式，或者建议一些用于相同公式计算的链接

Hello as my creating simple GPS application in c# but i want to convert the the earth latitude longitude in kilometer i had formula for that bit i am not sure whether the calculation given by that formula is correct or not.here is the formula for that this formula is in the VB

xtmp0 = ((69.172 * Cos(0)) * 1.609344) * Val(longitude)
ytmp0 = (((68.703 * Val(latitude))) * 1.609344)
please suggest me whether it is correct formula or not or suggest some link for calculating it for the same
