Unfortunately, this LiCSBAS repository cannot be updated since 2022 for a reason. Data downloading in step01 no longer works because of a critical system change in the COMET-LiCS web portal in June 2024. Please use LiCSBAS2 or COMET-version LiCSBAS which are maintained instead.

LiCSBAS

LiCSBAS is an open-source package in Python and bash to carry out InSAR time series analysis using LiCSAR products (i.e., unwrapped interferograms and coherence) which are freely available on the COMET-LiCS web portal.

Users can easily derive the time series and velocity of the displacement if sufficient LiCSAR products are available in the area of interest. LiCSBAS also contains visualization tools to interactively display the time series of displacement to help investigation and interpretation of the results.

COMET is the UK Natural Environment Research Council's Centre for the Observation and Modelling of Earthquakes, Volcanoes and Tectonics. LiCSAR is developed as part of the NERC large grant, "Looking inside the continents from Space" (NE/K010867/1). LiCSAR contains modified Copernicus Sentinel data [2014-] analysed by the COMET. LiCSAR uses JASMIN, the UK’s collaborative data analysis environment.

The Scientific Colour Maps (Crameri, 2018) is used in LiCSBAS.
