             abstract = "The satellite images acquisition involves geometric and 
                         radiometric deformations that must be corrected or minimized. To 
                         correct them, several methodologies and tools can be used, one of 
                         them being orthorectification, which minimizes the inclinations of 
                         the platform and provides an orthogonal projection of the images, 
                         so that reliable information can be extracted. To perform the 
                         orthorectification, it is necessary to generate the Digital 
                         Elevation Model (DEM) of the region, that will be used to correct 
                         the distortion of the terrain. In the process of DEM generation, 
                         different interpolators can be used to reconstruct the Earth''s 
                         surface. Considering the importance of the production of quality 
                         cartographic data from orbital images, the purpose of this work is 
                         to evaluate the positional accuracy of the products generated from 
                         orthorectification based on DEMs generated through the Topo to 
                         Raster, Krigagem, TIN and IDW interpolators for an IKONOS II image 
                         from Vi{\c{c}}osa - MG, using the technical specification for 
                         geospatial data quality control (ET-CQDG) of INDE. The DEMs were 
                         generated from contour lines, hydrography and elevation points 
                         data, available in the IBGE database, with 1: 50,000 scale. It was 
                         possible to identify that, in the generated orthoimages, the 
                         interpolator that presented the best result was the Topo to 
                         Raster, reaching class C on the scale of 1: 10,000 and the worst, 
                         the IDW, reaching class D in the scale of 1: 10,000.",
