I was going to post this a couple weeks ago but my internet was down.
I finally got me a 16 giga pixel map. Took 5 days to generate on a duo core 3.0 ghz
256 x 256 mosaic
nx = 131072
ny = 131072
HorizScale = 10.000000
MosaicFlag = true
MosaicSize = 512
Algorithm = "InflateDM256"
Now if only I could edit it. Well I can but I have to do it in chunks. LOL
