(June 2009) The BEAM development team proudly presents
1. the new BEAM 4.6 release,
2. the redesigned BEAM website including
3. a new BEAM user forum!
BEAM 4.6 comes with some interesting new features, namely the new layer and session management. With the new forum we hope to establish an vivid community where BEAM users ask questions, provide solutions and share their knowledge.
The forum is moderated by the BEAM development team and our experts wont let any problem unacknowledged.
Originally developed to facilitate the utilisation of image data from Envisat’s optical instruments, BEAM now supports a growing number of other raster data formats such as GeoTIFF and NetCDF as well as data formats of other EO sensors such as MODIS, AVHRR, AVNIR, PRISM and CHRIS/Proba. Various data and algorithms are supported by dedicated extension plug-ins.
- VISAT – An intuitive desktop application to be used for visualization, analyzing and processing of remote sensing raster data. To get an impression of how VISAT looks and feels like, please take a look at the related screenshots page.
- A set of scientific tools running either from the command line or invoked by VISAT, also entirely written in Java.
- A rich Java API for the development of new remote sensing applications and BEAM extension plug-ins.
This following table lists the data product formats which are supported by BEAM using the reader modules provided in the standard installation. Information about the access to these products is given on the data sources page.
|MERIS L1b/L2||Envisat||Envisat N1|
|AATSR L1b/L2||Envisat||Envisat N1|
|ATSR L1b/L2||ERS||Envisat N1, ERS|
|MODIS L2||Aqua, Terra||HDF4|
|AVHRR/3 L1b||NOAA-KLM||NOAA, METOP|
Generic EO Data Formats
BEAM supports the following generic raster formats:
|BEAM-DIMAP||read + write||The standard BEAM I/O format. It comprises an XML header based on the SpotImage/CNES DIMAP schema and ENVI images for the raster data|
|GeoTIFF||read + write||A widely used EO data format, e.g. for Quickbird, LANDSAT, SPOT|
|NetCDF||read||A widely used EO data format. BEAM supports NetCDF files conforming to the NetCDF CF Metadata Convention|
|HDF-EOS||read||BEAM supports the HDF-EOS profile (HDF4) used by NASA Ocean Color data products of SeaWiFS, MODIS, OCTS, CZCS|
