Google Earth Engine(GEE)——sentinel-1综合查看两个月前后自动滑坡监测,两者之间的差异(危地马拉为例)

上一次我们利用sentinel2进行了光谱分析,用的是指数计算NDVI,这一次为了更加进一步,我们结合sentinel1综合查看两者之间的差异。这里面需要注意的一点是我们可以通过自己选取点来查看,你要选取的点的位移信息。
代码:
/**
* * 为变化检测制作不同的图像。
* 预处理和可视化 Sentinel-1 雷达数据和 Sentinel-2 光学数据。
* S1 处理步骤已根据 Eric Bullock 的教程修改,[email protected],参见:https://www.youtube.com/watch?v=JZbLokRI8as&t=1210s
