It seems you already have plenty of offers for the address of Viewpoint, so I
won't reiterate that, however, I have a few numbers you could try to get
non U.S. digital terrain data. We use these to access the data we require to
1 800 USA MAPS will get you through to USGS who can provide some non US data
which is available through ftp sites. This is free for the low
resolution data (100m post spacing), but as I understand it,
they only provide certain areas of the world so it may be that
you are looking for an area they don't have. In which case, try:
1 800 ASK SPOT which is the number for Spot Image. They can provide almost
anything you require ...... at a cost!!! Their panchromatic
data is 10m resolution and the multispectral is 20m.
At Coryphaeus we would normally use DMA data for our terrain generator, EasyT
when it is available to us (the data and resolution is not always publicly
available) and we also use USGS DEM data which we are able to obtain through
an ftp site at 100m post spacing.
I hope this helps - if you have any more questions about how we obtain our
terrain data please contact me directly.
