  • 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 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
