                         (GIS) and considering the ease of obtaining orbital images and 
                         Remote Sensing data, implies an increasing need to obtain tools 
                         that can translate data from Remote Sensing, normally orbital 
                         images, in information, this work has as main objective to compare 
                         the two main active contour models, which are: parametric and 
                         geometric, known as Snakes and Level Set, respectively, to extract 
                         water bodies in orbital images. The proposed methodology was to 
                         make a qualitative comparison in this work. The images used to 
                         apply the models were binarized according to the well-known method 
                         of Otsu (1979), creating the same conditions for comparisons. The 
                         application of the active contour models were initialized with 
                         points, for the Level Set and small initial contours for the 
                         Snakes, always in the same positions. The methodology was applied 
                         in clippings of a scene taken in the Pantanal region of the State 
                         of Mato Grosso, with the PAN sensor, of the satellite CBERS-4, of 
                         April 2016. The results show that the application of the contour 
                         is directly linked to Characteristic of the feature in question 
                         and show that both models have reasonable behavior, given the 
                         characteristics of the features.",
