The potential of the upcoming high-resolution (1-m ground
resolution) satellite imagery for national mapping products is
discussed. An analysis of the capabilities of these high-resolution
imaging systems and existing satellite imaging systems
for the representation and extraction of elevation in formation,
such as terrain relief displacement and parallaxes, is
given. In-track and cross-track stereo mapping techniques using
satellite pushbroom CCD linear arrays are described. A
photogrammetric processing model considering such geometry
is introduced. Based on an error estimation and analysis,
it is concluded that, if the strict photogrammetric processing
model and ground control points are employed, high-resolution
satellite imagery can be used for the generation and update
of national mapping products (7.5-minute quadrangles
at a map scale of 1 :24,000), including Digital Elevation Models
(DEM), Digital Orthophoto Quadrants (DOQ), Digital Line
Graph (DLG) databases, and Digital Shoreline (DSL) database
