Zastosowanie normalizacji obrazu i transformacji składowych głównych PCA do wyznaczania typu pokrycia terenu na zobrazowaniach satelitarnych Landsat 7/ETM+ podczas wezbrań w Basenie Dolnym Biebrzy

Landsat 7/ETM + image processed with method taking advantage of ratio images and Principal Component Analysis - PCA was put to Supervised Classification. Classification was carried out with Maximum Likelihood Classification method on the basis of land cover classes determined upon ground exploration data and complementary data as topographic and thematic maps of investigated area. Analysis of satellite image was executed in ER Mapper 6.1 with out thermal and panchromatic band. Results were compared and usefulness of foregoing methods to determine land cover in the area of flooded river basins was given.
