                         topographic maps based on orbital remote sensing data was 
                         investigated for mountainous terrain of the Caraj{\'a}s Mineral 
                         Province (Par{\'a} State), Brazilian Amazon. Radargrammetric 
                         digital elevation models (relative and absolute DEMs) were 
                         obtained from Fine-Mode RADARSAT-1 stereo-pairs (F2, F5) and 
                         evaluated with regard to their altimetric information. The DEM 
                         extractions were based on a geometric modeling (RADARSAT-1 
                         Specific) available at the OESE software (PCI Geomatics). The 
                         planimetric features were extracted from digital integrated 
                         Fine/ETM+ Landsat 7 products. Precise planialtimetric information 
                         from DGPS (differential global positioning system) field campaign 
                         was used as GCPs (ground control points), for the modeling of the 
                         absolute DEM and the orthorectification of the radar and optical 
                         data, or as ICP (independent check points), for the calculation of 
                         planialtimetric accuracy of the topographic map. The 
                         planialtimetric accuracy of the topographic map has met the 
                         requirements for 1:100,000-map (semi-detailed scale), class B, as 
                         requested by the Brazilian Standard for Cartographic Accuracy 
                         (PEC). The investigation was carried out as an INPE-Geoambientes 
                         project with funds from FAPESP and supported by CVRD.",
