Some powershell/shell/python scripts I use to download or simply process GIS/RS data

• this is a basic powershell script
• Download mosaicked MODIS product published on gscloud (地理空间数据云)
• Need browser cookie to download, e.g. copy it from Chrome DevTools to the script
• there are always some false download result when you download from gscloud, and i dont know why.... users have to pick them out and re-download

I made some tweaks on the downloading script nasa provides. Screen output is now saved into dl.log, and failed files are recorded into failed.txt.

Using aria2c to download, which is much faster because of multithreading. Require aria2c installed.

usage:

• First replace the username in Download.sh with your nasa earthdata username
• Get the links of files from nasa earthdata website. e.g. links.txt
• Run the Script: ./Downloadxxx.sh <links.txt>
• Check if there are failed files in failed.txt and re-download them

• add failed files check in nasa earthdata aria2c download
