BRAT - Basic Radar Altimetry Toolbox README

===========================================

Version History

===============



2.1.1 - June 2010

---------------------

  - Bugs fixed :

    * Regression issue in 2.1.0 that broke support of high resolution and

      waveform data for ENVISAT RA-2 and ERS RA products.

    * Possible loss of field names in expressions that contain aliases

    * Wrong SSH formula for Topex product (SSH_TOPEX) (since BRAT 2.0.0):

      'Topex dual-frequency ionospheric (Iono_Cor) correction' should be used

      instead of 'Ionospheric correction from DORIS (Iono_Dor).

    * When executing an operation within Brat GUI, expression is sometimes

      reset if it contains a syntax error.



2.1.0 - March 2010

---------------------

  - Updated RA2 product format specifications (codadef) to bring them in line

    with the new Vol14 4/C product format specifications document.

  - Improvements to the CRYOSAT product format definitions (codadef) file to

    bring it in line with the latest official specification documents.

  - Updated CODA to version 1.3.3.

  - Bugs fixed :

    * The Matlab API 'brathl_ReadData' could crash depending on how parameters

      were passed to the API.

    * BratDisplay could crash due to an invalid pointer.

    * Incorrect fieldname for Export if 'Only dump expressions' was selected.

    * Fixed column header for 'date as period' values in ascii export.



2.0.3 - November 2009

---------------------

  - Bugs fixed :

    * An uninstall of BRAT would delete the entire installation

      directory (/usr/local by default on Linux when installed as

      root), including non-BRAT files and directories.

    * BratExportAscii : issue with the FIELD_FORMAT parameter

      which is not taken into account from the export parameters' file

	  (Notice that FIELD_FORMAT parameter is never set by using BratGui

	  and have to be set manually in the parameters' file).

    * Get rid of 'RPM' error messages after a root install on

      Linux.



2.0.2 - November 2009

--------------------

  - Bugs fixed :

    * On Windows, BRAT could be looking on the wrong drive for its data files

    * Fixed a few potential memory leak and memory corruption problems

    * Uninstaller on Windows will now properly remove all files



2.0.1 - June 2009

-----------------

  - Bugs fixed :

    * Compilation errors under Linux X64

    * BratDisplay sometimes crashes on close.

    * BratGui sometimes crashes when refreshing the display panel

    * Some minor issues.



  - Improve 'ascii export' report (from Netcdf products).



2.0.0 - April 2009

------------------

  - This update is a major upgrade of the software, including a Mac OS X

    version, River&Lake data reading capability, full waveform processing and

    plotting, new plotting capabilities, export in GeoTiff, including a Google

    Earth export feature, easier export in ASCII, a rethinking of the Graphical

    User Interface and of the software packaging, to make it easier to use.



1.1.1 - June 2008

----------------------

  - Bug fixed : In Brat Gui, Loess filter is never applied. Bug

    appears in version 1.1.0.



1.1.0 - December 2007

----------------------

  - Bug fixed : sometimes the toolbox (GUI) crashes when you

    delete an operation.

  - Add Jason-2 data processing.

  - Add 'General' NetCdf data processing.

  - Built under linux with GCC 4.2.2 (new warnings)



1.0.2 - March 2007

------------------

  - Bug fixed : In X/Y plot display, sometimes the toolbox

    crashes when moving the graph after having modified the font

    size.

  - Disable 'barn' unit.



1.0.1 - December 2006

---------------------

  - Add high-resolution fields processing.

  - Installation process and package creation enhanced.



1.0.0

-----

  - First released version.







Known Issues

============



+ Due to a conflict between the openSUSE 11.1 Linux operating

system and the InstallBuilder 5.4.13 software used to create the

binary installer for BRAT (the symptom is a "Segmentation Fault"

crash when attempting to run the installer), BRAT cannot

currently be installed on such systems and will have to be

compiled from source instead.
