This network utilizes reflectance difference images from pre- and post-landslide Sentinel-2A images, along with digital elevation model (DEM) data. Moreover, a multichannel differential landslide dataset was constructed through spectral analysis of Sentinel-2A images, which facilitates network training ...
推荐联网自动下载DEM数据,导入外部DEM数据可能会报错。按下图设置好参数,红框标注的是几个需要注意的地方。DEM推荐使用SRTM 3Sec(Auto Download)或SRTM 1Sec HGT(Auto Download),两者的区别主要是分辨率(90 m /30 m)。影像分辨率保持默认10 m即可,取消勾选Mask。点击Run会自动下载DEM,执行地形校正,笔者测试时进行...
,需要将Sentinel数据、DEM数据导入到SARscape软件中,生成SARscape能够识别的格式1.导入Sentinel-1A数据2.导入DEM数据导入结果: 裁剪数据哨兵数据的一幅的跨幅很大,不建议全幅处理。可对其进行裁剪,裁剪的结果尽量要被DEM所覆盖1.哨兵数据裁剪教程 裁剪结果 配准 将两个SAR影像进行配准 【工具位置】/SARscape/Basic/Int...
使用SNAP做DEM,需要安装一个第三方插件:snaphu,官网为https://web.stanford.edu/group/radar/softwareandlinks/sw/snaphu/ 在这里插入图片描述 ### 1.2.1 Windows系统安装snaphu 1. 如果是Windows系统,点击Tools,选择Plugins 在这里插入图片描述 2. 在弹出的窗口中选择Available Plugins中点击SNAPHU Unwrapping,选择左...
哨兵-2 Sentinel-2 数据下载(欧空局) 2.2 DEM数据下载与放置 做DInSAR有多个方法,本文使用是两期SAR数据+DEM,因此要事先准备DEM数据,通常使用SRTM数据,具体来说是SRTM-1 V3,分辨率30m。 虽然SARscape理论上可以自动下载DEM,但是国内的网络经常出故障,因此还是需要手动下载。

First, they were spatially co-registered using the 3-arcsec Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) (USGS, 2019). Afterwards Differential interferograms were generated, multilooked and Goldstein phase filtering was employed. The differential phase is composed of ground ...
