                         areas within the Brazilian territory still present a lack of 
                         planialtimetric information at both semi-detailed (1:100,000) and 
                         detailed (1:50,000) map scales, mainly at the Northern and 
                         Northeast regions. In addition, topographic maps when available 
                         are outdated and with poor altimetric quality. Digital Elevation 
                         Models (DEMs) are primitive inputs for topographic mapping 
                         production, and the usage of orbital remote sensing data for DEM 
                         generation is a promising alternative to overcome this overall 
                         absence of terrain information. In this study, several DEMs 
                         generated from optical (ASTER) and radar (RADARSAT-1, Shuttle 
                         Radar Topography Mission-SRTM) remote sensing and based on 
                         distinct methodology (stereoscopy and interferometry) were 
                         generated and evaluated for topographic mapping purposes. As a 
                         test-site, an area of 9,000 square kilometers was selected in the 
                         Caraj{\'a}s Mineral Province, a mountainous terrain located on 
                         the eastern most border of the Brazilian Amazon region. The 
                         geometric modeling for the DEMs extractions was based on the OESE 
                         software (PCI Geomatics). Precise topographic field data from 
                         static and kinematic GPS (Global Positioning System) was used as 
                         GCPs (Ground Control Points) for the modeling of the DEMs and 
                         ortho-rectification of ancillary optical data (ETM+ Landsat), and 
                         as ICP (Independent Check Points), for the calculation of 
                         altimetric accuracies of the products. In addition, a comparative 
                         analysis was also carried out considering the altimetric 
                         requirements for national topographic mapping based on the 
                         Brazilian Standard for Cartographic Accuracy (PEC Padr{\~a}o de 
                         Exatid{\~a}o Cartogr{\'a}fica). The investigation has shown that 
                         the DEMs accuracies derived from ASTER and SRTM data, which were 
                         generated and evaluated with a well-distributed set of GCPs and 
                         ICPs, respectively, met the requirements for 1:100,000-map (class 
                         A) as requested by PEC. The altimetric information provided by 
                         Fine and Standard RADARSAT-1 has only fulfilled the PEC 
                         requirements for 1:100,000-map classes B and C, but these results 
                         were affected by a poor area distribution and small numbers of 
                         GCPs and ICPs, respectively, available for the DEMs generation and 
                         accuracy evaluation.",
