Pretty much anything by Shinkai and Studio Ghibli (for the latter I particularly suggest Iblard Jikan, which is essentially a collection of animated sceneries) (most of both can be found on BD, for Ghibli some things are even actual 1080p).
As already stated, Mushi-Shi also has many sceneries, but it is unfortunately an SD only sources (the BDs are an upscale from 480p).
Some other interesting scenaries can be found in Sarai-ya Goyou (the TV air was effectively 720p, but it was only released on DVD).
For "space" scenaries, I'd recommend PlanetES (BDs have been released, it's not a SD upscale, but it doesn't even reach actual hd ready detail ─ it's probably superpal, so like 1024x576 of actual detail).
Gin`iro no Kami no Agito (Origin - Spirits of the Past) also had quite a few good sceneries. IIRC it was just 720p, but perhaps it had higher detail.
