实现的方法是缩放到一个整数的缩放级别(可尝试一个任意的固定比例尺以便观看不同值的效果)并通过纬度和经度定义一个点。

You do this by zooming to an integer zoom level (an arbitrary fixed-scale experiment to see the effect of different values) and defining a point by latitude and longitude.

然而，可以证明再开始的GMRES算法：GMRES (m)，有可能发生停滞，这里m为某一固定的整数。

However, it is possible to show that the restarted GMRES methods, GMRES mis some fixed integer parameter, may be stationary.
