GMTSAR软件InSAR时序处理流程

1.Download InSAR data

 nohup python3 ./download-all-2023-11-01_12-08-11.py > T85_download.log &

2.generated SAFE filelist

ls -d /home/wx/gmtsar_sbas_test/data/*SAFE > filelist 
 
sed 's|^/data2/xinw/HMF_Sentinel1_data/T85/T85_SAFE/||' filelist | sort -t '_' -k 7,7 -k 8,8n -k 9,9n | sed 's|^|/data2/xinw/HMF_Sentinel1_data/T85/T85_SAFE/|'
 
sed 's|^/data2/xinw/HMF_Sentinel1_data/T85/T85_SAFE/||' filelist | sort -t '_' -k 7,7 -k 8,8n -k 9,9n | sed 's|^|/data2/xinw/HMF_Sentinel1_data/T85/T85_SAFE/|' > filelist_sort
 
sort -t '_' -k 7,7 -k 8,8n -k 9,9n filelist > filelist_sort

3.Download orbit

download_sentinel_orbits_linux.csh filelist 1

filelist:
    absolutepathto/filename1.SAFE
    absolutepathto/filename2.SAFE

     mode 1 = precise orbits (POEORB)
            (most users should choose precise orbits)
    mode 2 = temporary (restituted) orbits (RESORB)

4.Download DEM

make_dem.csh -156.1 -154.8 18.8 19.7

5.拼接burst

organize_files_tops_linux.csh filelist pins.ll 1 看看多少数据覆盖
 
organize_files_tops_linux.csh filelist pins.ll 2
 
 ls -lht F0301_F0304/*/measurement
 
ls *SSV_20151006*/preview 
scp -r  xinw@114.214:/data2/xinw/HMF_Sentinel1_data/T85/T85_SAFE/S1A_IW_SLC__1SSV_20151006T122221_20151006T122248_008032_00B3EF_006D.SAFE/preview ./preview3

6. 超链接

~/gmtsar_sbas_test/F2/raw$ ln -s  ../../organized/F0301_F0304/*/*/*iw2*vv*tiff .
~/gmtsar_sbas_test/F2/raw$ ln -s  ../../organized/F0301_F0304/*/*/*iw2*vv*xml
