Abstract: The purpose of this paper is to present the results of the assessment of Digital Elevation Model (DEM) generated from the IKONOS images stereo pair. The DEM was generated by an automated photogrammetric process in the software ERDAS LPS ATE. The methodology is based on rational function polynomial using the Rational Polynomial Coefficient (RPC) as the main information on triangulation and DEM extraction. The DEM is a cartographic product key for study and analysis of altitude. So evaluate the accuracy of even become indispensable for these product is reliable source of information for project about environmental management and territorial planning. Were used to evaluate the parameters required by Padrão de Exatidão Cartográfica (PEC). The study area was the city of Luís Alves, situated in the northern state of Santa Catarina.

 Keywords: Rational Polynomial Coefficient, Process photogrammetric rational function polynomial
