BESTGUI is a GUI front-end for BEST written in Python and GTK+. BEST (Basic Envisat SAR Toolbox) is an ESA (European Space Agency) software tool designed to facilitate the use of ESA SAR data.
sarface is a user-interface to the sysstat/sar database which inputs data from sar and plots to a live X11 graph via gnuplot. It mimics the cmd-line options from sar but can cross-plot any two or more stats and apply simple mathematical functions them.
