I just completed formatting all the TACs for the US (including Alaska and Puerto Rico) to be visible in Google Earth. There are two versions of the maps, an online version and an off line version. The off line version has much faster tile load times and higher resolution than the online version. But you'll need about 15-20 megs of hard drive for each map that you want to use off-line.You can download them here: http://www.topomaps.fox-fam.com/I'm in the process of doing all the Sectionals (including Alaska this time) in this same format.Now If I could just find someone with a large format scanner, I could do the Enroute Charts.Matt
