Accurate digital terrain model are essential to a number of scientific
and commercial applications, in particular natural resources,
utilities and mobile communication systems.
SAR Interferometry presents an important new tool for the production
of accurate digital terrain models comparable to optical based
systems such as SPOT.
The method of creating a DEM is discussed in a companion paper
"The UCL 3D Image Maker system for DEM generation from SAR
interferometry" (IFSAR-3DIM) by Muller, Mandanayake, Upton
in this workshop.
This paper presents an accuracy assessment of DEMs derived from
ERS tandem interferometry, including a detailed description and
results of the IFSAR-3DIM process over 2 study sites: Montagne
Saint Victoire and Mt Etna as well as a quantitative comparison
with SPOT-stereo using panchromatic SPOT data.
