在数字高程模型(DEM)允许误差的条件下，一定存在最优基线使得DEM精度最佳。

In the condition of acceptable Digital Elevation Model (DEM) error, there must be an optimal baseline which makes DEM precision highest.

我看到这一个，我就去她说，我和我的冤家她让我思考，那就是当我说在数字高程模型的女孩，女孩？

I seen this one, I'm bout to go in Then she said, I'm here with my friends She got me thinking, thats when I said Where dem girls at, girls at?
