Local History Mashups

Is anyone mashing their local history material with a cartographic application, like say Google Maps or even better Wikimapia, to geolocate local history material? Something like a geolocated memoryarchive.org for local material? While browsing local history photo's (even those with corresponding addresses) I often find myself wondering, "Now where the heck is that?"

Open-sourcing the content and inviting the community to submit their own local history via an application like Wikimapia could be even better. Local history could be captured with a depth and scope that otherwise would be impossible.

Imagine how much more could be captured and saved if the entire community was involved in sharing their own stories and connecting it to place. Stories from Grandpa's shop could be shared and connected to where it once stood. Ditto on stories from Grandma's college days.

You could even share the spot where your uncles faked finding a crash-landed Skylab by dousing a lawnmower engine with gasoline and lighting it on fire - perhaps linking it to the resulting media coverage (Yes, I have to admit I know some uncles who did that....)

Hmmm, how much more of the 99% of history could be saved by visually tying it to place and enlisting the community to share their most meaningful histories.....
