| BRAT - Broadview Radar Altimetry Toolbox README | |
| == == == == == == == == == == == == == == == == == == == == == = | |
| Overview | |
| == == == == | |
| The Broadview Radar Altimetry Toolbox (BRAT) is a collection of | |
| tools and tutorial documents designed to facilitate the processing | |
| of radar altimetry data. BRAT is able to handle most distributed | |
| radar altimetry data formats, providing support for ingesting, | |
| processing, editing (to a certain extent), generating statistics, | |
| visualising and exporting the results. | |
| A full user manual for BRAT is available in the file | |
| brat_user_manual.pdf in the 'doc' directory of the BRAT | |
| distribution or installation.The user manual contains all the | |
| necessary information about installing and running BRAT. | |
| This README file contains the version history for BRAT, a list of | |
| known issues, and any other last - minute added or updated | |
| information that can not( yet ) be found in the user manual.In | |
| the case of conflicting information, this README file is | |
| authoritative. | |
| Known Issues | |
| ============ | |
| - Window Buttons in Gnome Desktop | |
| The software recognizes Gnome when when running in a Linux desktop | |
| and sets the appropriate properties for the minimize, maximize and | |
| close buttons to be displayed in view windows. However, in Debian 8 | |
| it was verified that additonal configuration steps might be necessary, | |
| at the system level, for those buttons to be dislayed. | |
| This issue, which affects not only BRAT but other GUI applications | |
| as well, can be solved by running | |
| gsettings set org.gnome.desktop.wm.preferences button-layout appmenu:minimize,maximize,close | |
| and by calling gnome-tweak-tool from the command line and then | |
| selecting "Windows", "Titlebar Buttons", and clicking "ON" for the | |
| maximize and minimize buttons. | |
| - Spurious error messages about map projections | |
| The first time a view is displayed in a BRAT GUI session, it is | |
| possible that messages like | |
| "ERROR 6: EPSG PCS/GCS code 54003 not found in EPSG support files." | |
| "Is this a valid EPSG coordinate system?” | |
| are printed to the console. These messages are not issued by BRAT | |
| itself and the reasons why they originate have no consequences on | |
| BRAT functionality. They can be safely disregarded. | |
| - Troubleshooting BRAT startup issues caused by OpenGL check failures | |
| By default, when the BRAT GUI application starts, some tests are executed | |
| to evaluate the system's OpenGL capabilities. The user can then be alerted | |
| if some 3D views (3D plots or the globe) have limitations or are not | |
| displayed at all. In some systems, the Qt framework is not always able to | |
| recover from these test failures, and the application crashes without | |
| being able to circumvent the error and/or display any warnings to the user. | |
| If BRAT cannot start, this is the most common reason, namely in virtual | |
| machines. To disable these default checks, and allow BRAT to start | |
| nevertheless, please see the BRAT Software User Manual, section “3.7. | |
| Troubleshooting OpenGL issues”. | |

| Known problems with the V4.0.0-beta release: | |
| - Contours: | |
| Contours are only available for spectrograms (by selecting "Contour" options inside "Data Options" tab of | |
| the generated View). In the full release it will also be available for the Maps and Globe views type. | |
| - Vector Plots: | |
| Vector plots are currently not supported and will be implemented for the full release. | |
| - Log Scale: | |
| Logarithmic scale is currently not supported and will be implemented for the full release. | |
| - Colour Table: | |
| Currently it is not possible to select a custom colour table, and for this reason, for both type of plots, | |
| spectrogram and map, a default colour table is used. To be implemented for the full release a set of | |
| predefined colour tables. | |
| - Sampling and Filter: | |
| Sampling is the equivalent for the old "Set resolution and filter" feature. Currently this is not customizable | |
| and each time a plot of the type z=f(x,y) is computed, default values are used for the maximum and | |
| minimum of latitude (90 and -90 degrees respectively), maximum and minimum (180 and -180 degrees | |
| respectively) of longitude and a step of 1/3 degrees in each axis. Setting of the parameters to be | |
| implemented for full release. | |
| - Scheduler: | |
| Scheduler feature allows to postpone one or more operations, however this is not implemented yet, and | |
| will be available for full release. | |
| - Saving plot results in an image file: | |
| This feature would allow the user to save the Plot results in an image file (such as JPEG, PNG or TIFF), | |
| however was not implemented, and will be available for full release. | |
| - Aliases: | |
| Aliases are short names or unified names for data fields. There are NetCDF files read by Brat that do not | |
| have pre-defined aliases. This will implemented for the full release. | |
| - Export Operation: | |
| This option allows the user to export the current operation data to different formats (such as ASCII, | |
| NetCDF and GeoTIFF). This feature will be for the full release. | |
| - Show Info Button: | |
| Provides information about the original units (the ones defined in the data products) and the units used | |
| during computation or selection. This feature is not available yet and will be implemented for full release. | |
| - Faulty Map Projection: Nearest sided perspective: | |
| This projection is currently not working properly. | |
| 3.3.0 - September 2015 | |

| (Windows, Linux, Mac OS X); | |
| - update of build settings and source code to prepare the port to 64 bit | |
| architectures; | |
| - update to CODA version 2.13; | |
| - update to BitRock InstallBuilder version 15.1.0; | |
| - minor bug corrections. | |
| 3.1.0 - March 2012 | |
| ------------------ | |
| - Add an "aliases" capability, that enables users to use the same names for | |
| the most frequent data fields. | |
| - Add an index (brat_index_data) for data with a "time" dimension | |
| (i.e. not available for some data, like grids). | |
| - Add filters algorithms (four different filters have been implemented), | |
| working along-track or on grids. | |
| - The call to the geostrophic velocity algorithms is modified to use the | |
| aliases for longitude and latitude, to make things simpler for users. | |
| - Updated CODA to version 2.3.1. | |
| - Internal (CODA) product type names for ERS product types have been aligned | |
| with ESA naming convention (OPR_pass_file -> ALT.OPR, WAP -> ALT.WAP) | |
| - Updated CryoSat product format (codadef) to be in line with upcoming | |
| L1 PFS v4.9 and L2 PFS v2.8. Main changes impacting BRAT are: | |
| - The field for the main dataset in the FDM product is now called | |
| 'siral_l2_fdm_mds' instead of 'siral_l2_fdo_mds' | |
| - usr_corr field now has a scale factor of 1e-15 instead of 1e-7 | |
| - Fixed locating of User Manual document when selected from GUI. | |
| 3.0.1 - May 2011 | |
| ---------------- | |
| - Bugs fixed : | |
| * The Loess filters computation were not applied if input files were netCDF | |
| files. | |
| * Fixed problem where incorrect lines were drawn for worldmap plots on | |
| Windows due to rounding issues near the projection boundaries. | |
| * Fixed issue where a 'marque' (box with dotted lines) could appear in a | |
| worldmap plot. | |
| * Included MSVC 2010 DLLs to BRAT IDL and MATLAB directories on Windows to | |
| prevent usage problems of these interfaces. | |
| 3.0 - February 2011 | |
| ------------------- | |
| - Added algorithms computation module (geostrophic velocity algorithms). | |
| - Added batch processing : BratScheduler enables to delay the execution of an | |
| operation. | |
| - Added support for Topex-Poseidon and ERS RA waveform products. | |
| - It is now possible to drag & drop files into the Dataset panel. | |
| - Several improvements to BratDisplay: | |
| * the center/zoom functionality for worldplots has been greatly improved. | |
| * the number of latitude/longitude grid lines will now increase/decrease | |
| depending on the zoom level. | |
| * latitude/longitude grid lines now come with a text label showing the | |
| associated latitude/longitude value of the parallel/meridian. | |
| * the 'animation bar' is now shown by default if the plot can be animated. | |
| * Added support for new projections: Orthographic, Near-Sided Perspective, | |
| and Stereographic. | |
| * The save directory for image export will now be remembered for consecutive | |
| calls to export. | |
| * Added support to visualize vector plots. | |
| - Improve 'ascii export' : 'ascii export' is able to export either the result | |
| of the operation (default) or only dumps the expression data. In the | |
| previous version of Brat, 'ascii export' only dumped the expression data. | |
| - Updated CODA to version 1.5. | |
| - BRAT now requires VTK 5.6. | |
| - Bugs fixed : | |
| * Statistics computation are not converted to wanted unit (set by the user). | |
| * Display Expression Properties for a field were not updated properly in the | |
| Views tab of BratGui on Mac OS X. | |
| * The BRAT installer did now work on KDE SUSE 11 systems. | |
| 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 was sometimes | |
| reset if it contained a syntax error. | |
| * For Topex products, the date in Brat output was wrong if the Brat | |
| operation contained "high resolution" fields (data). | |
| 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 | |
