             abstract = "Wetland environment zones have great ecological interest whether 
                         permanently or eventually flooded. Its estimated that about 20% of 
                         South America territory is covered by wetlands. Although mapping 
                         is a preliminary step to the preservation process, its 
                         delimitation is still imprecise. The Santa Catharina South Plateau 
                         presents wetlands occurring intermingled with native meadows 
                         localized at 1000 meters of altitude. The aim of this study was 
                         mapping and analyzing the metric of wetlands by means of a 
                         Landsat-5 and SPOT-4 images. The research area involves 8174 ha, 
                         localized at south of Lages City (between 28°07- 28°10 S and 50°30 
                         50°22 W). After the pre-processing, Minimum Noise Fraction (MNF) 
                         transformation was applied to 3, 4 and 5 bands of the Landsat 
                         image; the images were classified with Maximum Likelihood method. 
                         The vectors generated by the semi-automatized classification were 
                         used to analyze the size, form, density and distribution of the 
                         wetlands. The permanent preservation areas (APP) were calculated 
                         according to State Laws. The SPOT image showed similar results 
                         comparing with Landsat image. Wetlands presented random 
                         distribution; areas varying between 0,02 65 ha (Landsat-5) and 0,1 
                         35 ha (SPOT-4); concentration of polygons smaller than 0,5 ha; APP 
                         occupying about 30% of total area. Therefore, the studied wetlands 
                         represented an expressive aspect of the landscape, in terms of the 
                         occupied area and also for their frequency and polygons 
                         distribution.",
