Hi! For an architectural project that involves a large, screen projected time zone watch we are looking for high quality earth maps and sattelite photos. Since the graphics will be projected via a HDTV video wall, the resolution of the images has to be rather high. so far, I've not been able to find any appropriate images here on CI$. If anyone could point me to an Internet site or CI$-forum or some commercial provider that would be great. Thanks, Kai Thomsen, ag4, Germany
