Viking.... Linux and Windows

[Zecatfish]

Check it out,
It can load your GPS track files, download topo layer for that trek or an road layer.
Theres a Windows Version and a Linux version.
IT can be used with a GPS receiver and log your treks on a laptop too.
It downloads the map tiles and saves them for use off-line could be handy for those that carry a netbook, you can have USGS terraserver topo reliefs along.

At one time it was downloading google maps too, but I think they removed it because it violated Googles terms of service.

ITs free too, but as with all the open soruce software, if you like it make a donation to the developers.

Sweet, thanks for the link!

My travel netbook just happens to dual-boot XP and Ubuntu 9. I prefer to spend my life in *NIX. This might be a good tool for my digital nomadic lifestyle.
