%X ABSTRACT. The objective of this paper is to assess Radar spatial resolution degradation effect on the identification and mapping of fluvial geomorphology features from the Amazon floodplain. 25 m resolution Standard Mode RADARST image was degraded to 100 m resolution using the same process applied to produce JERS images. The main steps in the research were: legend definition; data base implementation, image processing, geomorphological mapping, quantitative assessment of resolution effect. The area of each fluvial landform class and each lake class was computed for both radar productis: original and degraded resolution. Results showed that: marginal levee and lake deposition fan were more subjected to changes related to spatial resolution degradation; there is a non-proportional relationship between lake area and lake number in the floodplain region.
