> A weird PR press release: An internet photo printing service announces that it can print screenshots of views that you’ve taken with Google Earth and sent to them. But why not just use the built in Save Image command? And send them to any photo printing service? We’ll never know.

> ArchAtlas uses satellite imagery to illustrate ancient history. They’ve now started putting some of their locations onto Google Earth and NASA World Wind. Worth watching, as they have some other animations (the spread of farming, trade routes) that would work great as time-delimited layers for Google Earth. (Via Archeoastronomy)
