Re: [其他] 坐標比例計算
※ 引述《hfuman ()》之銘言：
: 不好意思 在這請教一個問題
: 已知相對坐標
: A(-0.3521,0.4463)
: B(-0.04 ,-0.404)
: 已知經緯度坐標
: A':121.215427,25.014413
: B':121.216686,25.01388
: C':121.216264,25.013777
: D':121.216461,25.014468
: 不知道這些數值能否求出C與D的相對坐標?
Let x=0.3121/0.001259
y=(-0.8503)/(-0.000533)
C=A+(x*0.000837, y*(-0.000636))
D=A+(x*0.001034, y*0.000055)
