BEAM, the Basic ENVISAT Toolbox for (A)ATSR and MERIS, is a collection of executable tools and Application Programming Interfaces (APIs) which have been developed to facilitate the utilisation, viewing and processing of ENVISAT MERIS, AATSR and ASAR data. The purpose of the BEAM is not to duplicate existing commercial packages, but to complement them with functions dedicated to the handling of ENVISAT MERIS and AATSR products.
The main components of the BEAM are:
This following table lists the data product formats which are supported by BEAM using the reader modules provided in the standard installation. Information about access to these products is given on the Data Sources page.
|MERIS Binned Level-3||Envisat||netCDF|
|TM Thematic Mapper||Landsat 5||Fast Format|
|NASA Ocean Color (OBPG)||MODIS A/T, SeaWiFS, OCTS, CZCS||HDF|
VISAT and the scientific data processors use a simple data input/output format, which makes it easy to import ENVISAT data in other imaging applications. The format is called DIMAP® and has been developed by SPOT-Image, France. The BEAM software uses a special DIMAP profile called BEAM-DIMAP, which has the following characteristics:
The complete BEAM software has been developed under the GNU public license and comes with full source code (JavaTM).
BEAM is programmed in pure Java to allow a maximum portability. The BEAM software has been successfully tested under MS Windows XP®, Windows Vista, Windows 7 and also Mac OS X and as well as under Linux and Solaris® operating systems.
