Almost exactly a year ago we got a preview of a phenomenal map about the history of DC buildings. Of course the map was immediately taken down for some reason. Well it is back and in full effect! Thanks to Betsy for sending from the DC Office of Planning:

“The D.C. Historic Preservation Office announces the launch of HistoryQuest DC, a GIS-based web map that provides historical data on approximately 127,000 extant buildings in Washington, D.C. The historic data is easily retrievable and can be queried and mapped, providing a new tool for illustrating the city’s building history and patterns of urban development.”

As I said the first time we saw it – Warning a serious time suck in the best of ways for those of a particular proclivity. Perfect for this rainy day!!
