             abstract = "The Brazilian Amazon is a vast territory with an enormous need for 
                         mapping and monitoring of renewable and non-renewable resources. 
                         Due to the adverse environmental condition (rain, cloud, dense 
                         vegetation) and difficult access, topographic information is still 
                         poor, and when available needs to be updated or re-mapped. In this 
                         paper, the feasibility of using Digital Surface Models (DSMs) 
                         extracted from TerraSAR-X Stripmap stereo-pair images for detailed 
                         topographic mapping was investigated for a mountainous area in the 
                         Caraj{\'a}s Mineral Province, located on the easternmost border 
                         of the Brazilian Amazon. The quality of the radargrammetric DSMs 
                         was evaluated regarding field altimetric measurements. Precise 
                         topographic field information acquired from a Global Positioning 
                         System (GPS) was used as Ground Control Points (GCPs) for the 
                         modeling of the stereoscopic DSMs and as Independent Check Points 
                         (ICPs) for the calculation of elevation accuracies. The analysis 
                         was performed following two ways: (1) the use of Root Mean Square 
                         Error (RMSE) and (2) calculations of systematic error (bias) and 
                         precision. The test for significant systematic error was based on 
                         the Students-t distribution and the test of precision was based on 
                         the Chi-squared distribution. The investigation has shown that the 
                         accuracy of the TerraSAR-X Stripmap DSMs met the requirements for 
                         1:50,000 map (Class A) as requested by the Brazilian Standard for 
                         Cartographic Accuracy. Thus, the use of TerraSAR-X Stripmap images 
                         can be considered a promising alternative for detailed topographic 
                         mapping in similar environments of the Amazon region, where 
                         available topographic information is rare or presents low 
                         quality.",
