                         in the identification and monitoring of special areas, it can be 
                         implemented in the short term and on different scales. This makes 
                         it possible to analyze the changes occurring in a given time 
                         interval, enabling the decision-making. This study aims to use 
                         these technologies to identify environmental impacts in Permanent 
                         Preservation Areas (PPA) of the watershed of the {\'A}gua Branca 
                         Creek, located in the eastern of the city of Goi{\^a}nia. It were 
                         used data from the Urban Basic Digital Map of Goiania (UBDMG v.22) 
                         which was manipulate using the software Quantum GIS. Images 
                         provided by Google Earth were also used in this study. PPAs have 
                         been drawn from the springs 100 meters and 50 meters of water 
                         sources along the watershed of that stream. The track was defined 
                         according to Complementary Law No. 171 of May 29, 2007, the Master 
                         Plan of Goi{\^a}nia. The results obtained allowed to identify and 
                         evaluate points of degradation of the PPA of the {\'A}gua Branca 
                         Creek and the watercourses of it sub basin, impacts resulting from 
                         direct and indirect human action. The use of GIS tools and remote 
                         sensing made it possible to study the sub basin of the creek 
                         {\'A}gua Branca which is located in a region with high housing. 
                         In addition, the watershed is part of Meia Ponte River basin, a 
                         source of extreme importance because it is used for water supply 
                         part of the metropolitan region of Goi{\^a}nia-GO.",
