BEST is a collection of executable software tools that has been developed to facilitate the use of ESA SAR data. The purpose of the Toolbox is not to duplicate existing commercial packages, but to complement them with functions dedicated to the handling of SAR products obtained from the ASAR (Advanced Synthetic Aperture Radar) onboard Envisat and the AMIs (Active Microwave Instrument) onboard ERS 1/2.
These pages give you access to the BEST software and to the information you will need to run it. The buttons on the left provide access to:
Input Data Products
The Toolbox has been designed to handle ESA data products from both the Envisat ASAR instrument and the AMI on ERS 1&2.
ASAR data acquired in Image Mode, Wide Swath Mode, Alternating Polarisation Mode or Global Monitoring Mode may be input, along with ERS image data processed both by the VMP processor and by the ERS PGS processor (CEOS and Envisat format). The Toolbox is capable of reading all Level 1b processed data and, in the case of ERS data, products from all 4 ESA Processing and Archiving Facilities plus many "foreign" stations.
Example ASAR Data Products
Sample Envisat ASAR products can be downloaded from Earthnet Online
The tools are portable on the following platforms: Windows™ 98/2000/ME/NT/XP, LinuX, SUN(Sparc)
Human Machine Interface
The Toolbox has 2 graphical user interfaces that enable the operator to easily specify the processing parameters required by each tool.
