2024.8.1
dd27029
  • Refactored the Sentinel-1 _process_bursts function of the InSAR processor
  • Geocoding lookup tables (LUT) now uses a common DEM
  • No more LUT merging after processing, safer handling of burst overlap to avoid gaps
  • The processor uses a new function S1IWSwath.fetch_dem that downloads the DEM for all processed bursts
  • The DEM is now upsampled after download, not at terrain correction stage
  • Burst geometries are computed at S1IWSwath initialization and stored as a class member
  • Burst geometries are now used instead of GCPs
  • DEM cropping uses a buffer around the burst geometry
  • Fixed a bug in the load_metadata function: rfi files are filtered out from the metadata file search
  • Handling of non-float NaNs in DEM (at coordinate reading)
  • range_doppler function skips NaN values
  • Optimization: Using cache=True and nogil=True in coregister_fast and range_doppler
  • Optimization: avoid the creation of multiple small arrays by coregister_fast results in speedup
  • Bug fix: in the s1-core-demo notebooks, burst index testing has been corrected in the interferogram warping cell
  • Better test data
  • Wrote a test for the insar processor using this data
