Multi-temporal remote sensing study of spectral signatures of crops in the Thessaloniki test site
In the framework of a pilot project concerning the application of remote sensing techniques to agricultural statistics, a specific study of an area in Northern Greece was carried out. The aim of the study was to monitor the spectral signatures of some crops of economic importance, as they are depicted from satellite data (TM and SPOT), and to compare them by means of an objective multi-temporal analysis. Multi-temporal TM and SPOT data were used to combine the spatial resolution of SPOT with the spectral resolution of TM and gain flexibility in the choice of dates. This approach is expected to overcome ambiguities in the spectral definition of crops, but significant problems are introduced, due mainly to the different atmospheric conditions present at the various dates.
