Elisabeth,
One of the best places to find more information about these (and other) elevation products is the Digital Elevation Data Catalog from Bruce Gittings at the Univ. of Edinburgh. The URL is
http://www.geo.ed.ac.uk/home/ded.html
Another worldwide product is GTOPO30 elevation data at
http://edcwww.cr.usgs.gov/landdaac/gtopo30/gtopo30.html
but the resolution is also 1 kilometer.
Hope this helps,
Charley

Subject: DEM products
Does anyone use - or know anything about - these products, or
could suggest better quality products that show digital elevation
worldwide?
GLOBE (Global Land One-Kilometer Base Elevation) Version
1.0 - by NOAA has global DEMs
Map Render 3D - has world wide DEM coverage at 30 meter
resolution
Please email me directly, thanks!
Beth

See the NOAA's "GLOBE" (1 km DEM grid) data set at:
http://www.ngdc.noaa.gov/seg/topo/globe.shtml
... you could also use the Digital Chart of the World or VMAP0, both in VPF
format, and both having some terrain elevation data ... at 1:1M
scale. ...
