Heya David,
The Terrain Team does create a stratmap for <almost> every map we have. Although the general community has never really asked for them before, there's no reason that they can't be published and available to the community. I'll talk to our web gurus about perhaps setting aside some webspace on AHEvents.
These maps are 2048x2048 and pixel-based... so I'm not sure if they fit your definition of "high-resolution" or not.
In the meantime, please feel free to e-mail me or PM me about any specific stratmap you need... I'll happily send one along.
ps. Thanks for the offer of your server. Ideally we should keep them on an official events server, just for convenience sake. That way updates can be handled better, and version control won't be an issue.
