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are outdated and with poor altimetric quality.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.",
