代码第三行,大概意思就是根据参数的名字来获取这张影像,声明一个变量elevation,将这张影像(对象)赋值给这个变量。如果我们不知道这个函数的意思,可以去查一下官方的reference: 4~23行,声明一个数组,这个数组共有9个点要素(有坐标有名字)。我们可以再去查一下ee.Feature()和ee.Geometry.Point(),根据这个例子,我...

Roadway elevation data is critical for a variety of transportation analyses. However, it has been challenging to obtain such data and most roadway GIS databases do not have them. This paper intends to address this need by proposing a method to extract roadway elevation data from Google Earth (...
