I think I will have to postpone getting all the third-party stuff 64-bit, and just release without it. It'll be for existing users, not an official release, but I think most people won't care about the missing functionality, which affects just a few GDAL drivers.

I'm using Leveller quite a lot in my new workflow for ME-DEM and I'm hitting a wall on how large a file I can use. I need to be able to get 10K in there, but I can't at the moment. We're about to do a big run on the map. For anyone interested you can read about it here <http://www.outerra.com/forum/index.php?topic=326.30> http://www.outerra.com/forum/index.php?topic=326.30 Cheers, Carl
