Release Change Log

Last update: February 2009

Changes from version 4.2.1-a to version 4.2.2-b

  • Version 4.2.2-b is now able to also calibrate ERS – PGS Envisat format data

  • User manual updated 

Changes from version 4.2.1 to version 4.2.1-a

  • Version 4.2.1-a fixes a bug in the handling of the ground range to slant range conversion polynomial coefficients for ERS PGS PRI CEOS data, which caused a wrong evaluation of the image geographic positioning.

    Bugs fixed

  • Geographic coordinates evaluation for ERS PGS PRI CEOS data.

Changes from version 4.2.0 to version 4.2.1

  • Version 4.2.1 solves the problem in handling simultaneously WSM data processed before and after 11 April 2007, in which the "Doppler Grid Centroid ADS" field is enabled. 

  • The Geo Correction routine can be applied to ASAR IMP and ERS PGS IMP data*

  • The Geotiff and Tiff format have been modified to increase their compatibility with other SW

* see Known issues and bugs page

Bugs fixed

  • Full size handling of ERS PGS CEOS data.

Changes from version 4.0.5 to version 4.2.0

  • ERS product processed by the ERS PGS processor both CEOS and Envisat (MPH-SPH) format supported.

  • ASAR WSS new functionalities: Detection and azimuth mosaicking and Range mosaicking and multilook.

  • Calibration of ERS and ASAR* images acquired until 31st December 2008**.

* Version 420 is not able to handle simultaneously WSM data processed before and after 11 April 2007, in which the "Doppler Grid Centroid ADS" field is enabled.
** Use of new ASAR External calibration data (ASAR_XCA_AX)

Bugs fixed

  • Geotiff format generated by BEST now preserves radiometry without any numeric distortion and the geographic positioning is well computed.
  • Tiff format generated by BEST now preserves radiometry without any numeric distortion.
