My friend showed me this interesting article and product about an ASTER derived DEM (30m...yay!). Good news for all of the people outside the states that couldn't get their hands on 1 arc-second SRTM data. I haven't downloaded it yet but I look forward to playing with it.

just as a side note, SRTM was always available as 1arcsec for the US, to anyone in the world. So its the location inside/outside US, not people located inside/outside, that made the differerence
Yeah I was aware of that, my point was for people who wanted coverage outside the US. Coverage of the US wasn't pariculary useful for my work at home
Hans thanks for fixing it up, I got to excited and posted before reading!!

Finally managed to download some data and play with it. Looks nice so far, but the web interface is very slow and I've only managed to get it working in IE...
I've tried twice and never got connected – makes me wish for the days of webGLIS. Perhaps in a week or so the traffic will slow down, however this recent post in the popular Gizmodo website probably garnered a few geo-rubberneckers.
Could this an indication that the digital world is becoming a lot more spatially interested?
