John Resig points us to this article in Directions about Urban Mapping’s neato Cracker Jack-box mapping technology — which was covered here a year ago when it was called “Dynamap”. (The old site is completely gone, and they haven’t forwarded the domain to the nearly-identical-but-at-a-new-URL site; grumble.) Anyway, the article is a good exegesis of what the technology does and what it’s good for.
