Just messing around with overlay comparisons in Google Earth due to performance issues. I also ended-up comparing the noticable difference between custom processed imagery and imagery provided to Google, since I’m in there.
The first image is the default view taken from Google Earth. The second, a view of the same source-image from Digital Globe, custom processed for a client a while back.
My initial reason for messing around in Google Earth with overlays, was to try to figure-out why it seems like performance has degraded dramatically. Granted, I’m not using the SuperOverlay method for this — instead I’m viewing 256 x 256 JPG chips brought-in from a KMZ file locally. (But that’s really the core of the issue — that I’m loading locally and noticing a major load-time and performance problem.) I’m also noticing some degraded performance in loading SuperOverlay files as well, though it is better than the single region layer method.
