The main aim of the work was to develop methods of remote identification of marshes, detection of flooded territories, and classification of plant cover on the basis of data of satellites operating in the optical and microwave spectres in particular. The research is done in 2014 on the territories of the Rozwarowo Marshes nature protected area, located in the north-eastern Poland in the delta of Oder. The backscattering coefficients (°), calculated from Radarsat-2 (Phased Array type C-band Synthetic Aperture Radar) images registered at cross polarization VH on 26 September 2014 were applied for classification of main types of wetland communities. The peculiarities of plant cover are also discovered using Normalized Difference Vegetation Index (NDVI), calculated on the basis satellite image SPOT-6 on September, the 1st, 2014. The differences in the NDVI value within homogeneous segment of plant are caused, first of all by the soil moisture. Close connection between the soil moisture and the NDVI value for the main groups of plant cover is detected. The application of coefficients °VH/°VV, calculated on the basis of radar images at the polarization VH and VV and the big ray angle (above 40°) of incidence are suggested for identification of flooded territories.
