A small collection of Python3 scripts to download data from the COMET-LiCS Sentinel-1 InSAR portal. The licsar_web_tools_example.py shows two examples, but usage can be summarised below:
frameID = '014A_04939_131313' # As defined on the LiCSAR portal
date_start = 20190901 # YYYYMMDD
date_end = 20200101 # YYYYMMDD
download_metadata = True # the network of baselines, DEM etc.
between_epoch_files = ['geo.unw.png', 'geo.cc.png'] # Possible files: 'geo.cc.png', 'geo.cc.tif', 'geo.diff.png', 'geo.diff_pha.tif', 'geo_diff_unfiltered.png', 'geo_diff_unfiltered_pha.tif', 'geo.unw.png', 'geo.unw.tif'
epoch_files = ['geo.mli.png','ztd.jpg'] # Possible files: 'geo.mli.png', 'geo.mli.tif', 'sltd.geo.tif', 'ztd.geo.tif', 'ztd.jpg'
n_para = 4 # Parallelisation. The number of cores is a good starting point.
download_LiCSAR_portal_data(frameID, date_start, date_end, download_metadata, epoch_files, between_epoch_files, n_para)
This tool is designed to be used in conjunction with the COMET-LiCS portal. By finding a frame of interest and selecting "download":
The files available to be downloaded can be browsed:
There is also a conda .yml file included for building a suitable environment:
conda env create --file LiCSAR_web_tools.yml
This has only been tested on Linux (Ubuntu 18.04), so please get in touch if you encounter any bugs. Several of the functions and ideas used in this software were were taken from LiCSBAS: https://github.com/yumorishita/LiCSBAS
