Multidimensional Small Baseline Subset (version 2D)

  • The Multidimensional Small Baseline Subset version 2D (MSBAS-2D) software simultaneously processes multiple ascending and descending Interferometric Synthetic Aperture Radar (InSAR) data sets and produces either
    • one-dimensional (line-of-sight),
    • two-dimensional (horizontal east-west and vertical), or
    • opportunistically three dimensional (horizontal north-south, east-west and vertical) deformation time series with combined temporal resolution.
  • The set of linear equations solved by MSBAS-2D is usually rank deficient and is solved in the least-square sense by applying the Singular Value Decomposition (SVD) and the zero, first, or second order Tikhonov regularization.
  • The MSBAS-2D source code is written in C++ and is parallelized using OpenMP. It is linked to the Linear Algebra PACKage (LAPACK) library that provides SVD support and to the Geospatial Data Abstraction Library (GDAL) that provides GeoTiff support.
MSBAS-2D have already been used for measuring various ground deformation, including:
  • mining (Samsonov et al., 2013a,b, 2014b);
  • urban development (Samsonov et al., 2014a, 2016c; Samsonov and d’Oreye, 2017);
  • carbon sequestration (Samsonov et al., 2015; Czarnogorska et al., 2016);
  • permafrost aggradation and pingo growth (Samsonov et al., 2016b);
  • volcanic activities (Samsonov and d’Oreye, 2012; Smets et al., 2014; Samsonov et al., 2014d,c, 2016a).

The user manual, source code and test set for MSBAS-2D can be download from here. To demonstrate the capabilities of MSBAS-2D, a test set of ascending and descending RADASAT-2 data over the Barnes Ice Cap (Baffin Island, Nunavut, Canada) during December 2014 - May 2015 is included and is used throughout the user manual to illustrate the processing sequence.
