Abstract

The paper describes the progress and the preliminary results of the project entitled “Synergetic use of ASAR and SPOT data for land cover mapping and crop monitoring” carried out in the framework of ESA’s ENVISAT AO Projects (ID:783). The main data sources for this research are ASAR detected products: Image Mode and Alt.Pol Mode. Different polarimetric configurations for Alt.Pol Mode as far as for Image Mode are exploited jointly with a few different imaging angles. Additionally single look complex ASAR products both for Image Mode and Alt. Pol Mode are processed for coherence map generation. The interferometric pairs are chosen amongst the available sets of ASAR data acquired for the test site Malbork located in the North of Poland during 2003 growing season. The acquisition dates and imaging parameters were programmed regarding ASAR flight schedule and instrument availability. On each day of ASAR imaging a lot of parcels were observed and some bio-metric parameters of crops were measured. On the other hand the series of 5 optical SPOT images were acquired during period April-August 2003 for facilitating ASAR images interpretation and understanding. Both sensors are exploited jointly for examining the complementarity and synergism of them. All these measures were undertaken for achieving the main purpose of the project namely detailed mapping of land cover and agricultural crop types.
