We’ve been using Google Earth to create simple geo-mapping solutions for our clients. The tool is eye-poppingly beautiful. Best of all, its easy to create XML files containing client data that can be overlaid on the maps. As long as you’re using a fast, Windows PC, this is a robust solution for agile geomapping. We’ve been able to get 10,000 prospects graphed with no performance problems.

Best of all, when you zoom all the way out, the Google/Keyhole people have included actual stars in the sky. Here’s a little blue ball posing beside the big dipper.
