The BACCHUS-DOC Radar and Optical Campaign was an area mapping project of
vineyards near Frascati (Italy). ESA required high resolution geo-referenced airborne SAR data of different wavelength and polarisation (preferably polarimetric).
ESA's SPectra bARrax Campaign (SPARC) activity was part of the preparatory study for a proposed ESA Earth Explorer mission called SPECTRA. The objective was to collect a CHRIS/PROBA reference dataset for SPECTRA-related studies.
