You mean Tannewald, just east of Leipzig-Halle EDDP, Sprocky?
And you mean those Porshe Cayenne mini-SUVs?
I published areas mostly covered with heights and mountains before, as I find views there are most dramatic and beautiful. I did fly also around Warsaw and Beijing, a quality of view there depends much on a coverage quality.
Here's very useful service, where you can compare coverage of a few different map servers, especially Google Maps and Yahoo Maps:

Google wins, of course
A mesh: Sure, if you have a proper mesh then your impressions are much better. I used SRTM-based mesh for my pics.
But be aware that some (mostly cloudy) areas have awful holes in SRTM and this means bad distortions (peaks or holes). Then better use other, "hand-made" meshes for this areas, as LOD9-LOD10 meshes for all Himalaya by Holger Sandmann (search Avsim.com, much better then raw SRTM).
Tileproxy author does plan to implement on-line mesh download as well (!) but this time this would mean paying for that stuff a little as a dedicated server and bandwidth would be needed ...
