		<abstract>In Brazil, some institutions offer free of digital data that make up a cartography base  of the entire national territory. Mauro Borges Institute (IMB) provides files in shapefile format that include the cartography based on several topics, including, municipal limit and drainage in scale of 1/250,000, which may limit its use depending on the work objectives. This study aims to quantitatively compare the products generated from the use of Continuous Cartographic Base of Brazil and other generated from satellite imagery of high spatial resolution, on the outskirts of the city of Urutaí-Goiás. To achieve the goal, it was used the municipal limit provided by IMB and other defined manually using Google Earth images. These limits were extracted river enabling mapping Permanent Preservation Areas and comparing the results superimposed on the satellite image of high spatial resolution. It was found that on the whole the difference between the municipal limits was 14,731km where 93% of this total are located in boundary of the river. This is due to the different mapping scales. Through the results, we can see that Brazil Continuous Cartographic Base provides for various sources, vector features that can be used for various purposes, however, it is necessary to have parsimony in its use. So, in jobs that require a more accurate positional  is not possible to use the data provided by institutions such as the IMB, being necessary to map such features on scales that allow identification details.</abstract>
