Just found what looks like a very nice map ap for news organizations. Sky is using it and they’ve already caught a criminal via a map. More about it from the creator, Simon Dickson, here.
See also WashingtonPost.com’s really superb local explorer map ap, displaying businesses, home sales, schools (not sure why), and crime (I see the fine hand of Adrian Holovaty).
: Correction. Adrian, in the comments, says he had nothing to do with the Post’s local explorer. Except he has inspired all of us to think mappy.
