通过该算法模块，可以将离散数据生产出任意比例尺下的格网DEM数据，具有一定的实际意义。

In the algorithm module, the DEM data with any scale can be produced from scatter data, which is of significance.

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.
