The recent ERS tandem mission from ESA offers the potential to
create large area DEMs over a variety of different land cover
regions at unprecedented resolutions and accuracy. Studies at
UCL reported elsewhere at this meeting indicate that accuracies
which exceed the specification of the DMA DTED level 1 (3 arc-second
grid-spacing and 25m Zrms) can be provided by the automated generation
of DEMs from tandem pairs if surface wind conditions are not too
severe and night-time data is available.
An analysis of the potential of ERS tandem will be made using
data from ESRIN and presented at the workshop as well as a comparison
with the recently announced SRTM mission particularly for areas
northwards of 58N and 58S.
