For the whole of Eurasia.

I don't do ftp but surely the space shuttle data would be the US department of Defense data with 30
arc second spacing referred to earlier.

I think its closer than 30 seconds.... 3 seconds IIRC

Its certainly got the tech heads on rhb excited....

Whilst I don't have a website, as such, when I've got my Route sorted I put a screendump copy on
my website space and give address to whoever is acting as "safety". A couple of texts during the
hike to update location and I have the reassurance that when I fall into a crevasse someone'll
have some idea of where I am, when I fail to report in!!

Excellent idea!

No the 30 arc second data has been around for a long time and was known as Digital Terrain
Elevation Data or DTED. The recently released SRTM data is apparently available in 3 & 1 arc
second resolutions (I think the 1 arc sec data is only for the USA).

If the arc 30 second data was a spacing of 900 m the 3 as data would be 90 m and the 1 as 30 m. So
the European data would still not be as good as Anquet.

I haven't seen a comment yet on the resolution of Memory-map data. Have I missed anything?

I have been using the 2003 series of Memory Map for one year and am extremely pleased with them. I
find the resolution perfect and they will magnify to suit all needs, without any loss of definition.

I still haven't found out how to find the Legend of the series. It would seem that this is not
included in Memory Maps 2003 package. I aslo haven't found out how to enter a grid reference or
Lat/Lon and let the software take you to the location. Does anyone know how to achieve this?

The only way, I think, is to create a mark anywhere, then double-click it to bring up the properties
box. Edit the grid reference, and click *view*.

I use the same trick in Oziexplorer. Create a waypoint and edit it's position then in the waypoint
list "plot position of waypoint on map" or if it is off the map "find map for waypoint" first.
