The new interactive map is made available online by NYC Parks.
From TimeOut New York:
This week, the NYC Parks Department added an interactive map to its site that plots the location of every plaque, statue, memorial and temporary public art project on view. Just click on a pin (green for permanent object; white for temporary piece) and a box pops up with a thumbnail photo and description.
Gothamist also reports on this new resource and points out that it’s also searchable by Zip Code and address.
