== == == == == == == == == == == == == == == == == == == == == = 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”.

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 -------------------- - Correction of unhandled exception caused by not updading NetCDF file to reflect GUI changes. - Ensured build and run compatibility with CentOS 6 64 bits. - Enabled by default side-by-side installation of different BRAT versions and processor architectures on the same machine, without overwriting each other. - Updated available formulas (new formulas.ini file). - GUI applications display version and architecture, allowing easy runtime identification of different instances on the same system. - Python API examples can run immediately after installation, without further configuration actions like defining BRAT_DATA_DIR. - Correction of BRATHL 3.1.0 bug, caused by buffer overruns when reading a large list of files. - Correction of bugs caused by wxWidgets upgrade: - the Log tab in the application BratGui loosed its graphical layout and stability when resized; - the context menus of the tree widgets did not execute the expected actions and did not present all menu items. - Enabled C++11 support in g++ (Linux). - Windows XP support enabled by default in 32 bit binaries. - Update to NetCDF version 4.3.3.1. - Inclusion of new libraries, in integration with NetCDF 4 and CODA 2.13, deployed along with BRAT with their respective tools: - HDF5 version 1.8.15, - curl version 7.43 ( only in Windows ), - SZip version 2.1. - Extensions of BRATHL code to process NetCDF 4 and HDF 5, including new NetCDF data types. - Creation of a brathl dynamic module (brathl_module) encapsulating all BRATHL functionality to enable (autonomous) load and interface with Python. - New Python API to the BRATHL library, with examples. - Port to 64 bit of BRAT and all its dependencies, including - VTK 5.6.0 adjustments to enable 64 bit, - port to 64 bit of the BRATHL library, - port to 64 bit of the BRAT command line tools, - port to 64 bit of the BRAT GUI applications. - Updated wxWidgets to version 3.0.2. - Replaced Carbon by Cocoa framework in MAC OS X related code and build settings. - Updated BRAT GUI applications and libraries, with VTK support, as required by new wxWidgets version. 3.2.0 - June 2015 ------------------ Transitional release, preparing version 3.3.0 and focused on - update of build settings and source code to support current versions of operating systems, compilers and build systems in all supported platforms (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.

Further information =================== For software upgrades, documentation updates and the on-line tutorial, including use cases go to: http://earth.esa.int/brat/ or http://www.altimetry.info/ BRAT has been developed under contract with ESA.
Brat is installed and tried to connect, Cryosat, and Jason satellite to access the data. But Brat fails to synchronize
I had downloaded some in land file but when wver i try to execute WSH_Inland_Waters formula , a error /warning message appers on console and unable to see map.
Plz help

In Sentinel-3 data package there is always a xfdumanifest.xml, BRAT is complaning about this file in the import dialog if one just adds the Sentinel-3 data package (Sentinel-3 data is always distributed in the data package: one directory with manifest file + one or more measurements files in netcdf format).
The toolbox should ignore the file and not import it, the user has to remove it manually or the processing will not work.

Kindly provide other alternative link for downloading installer.
When switching to the tab "operations" I see the fields within the window "field" cannot be selected. I correctly charged an altimetry along track file and I can see the track in the map.
