The New York / New Jersey metropolitan region is home to several projects with many partnering organizations, community groups, and individuals. 

##Gowanus Canal Mapping##
The <a href="http://gowanuscanalconservancy.org/">Gowanus Canal Conservancy</a> is conducting environmental investigations in the Gowanus Canal sub-watershed using <a href="/tool/balloon-mapping">balloon mapping</a> to capture aerial imagery once per season for the past year. We are also flying a <a href="/tool/stereo-camera">stereo camera rig</a> to collect <a href="/tool/near-infrared-camera">infrared imagery</a>. We are looking for patterns/concentrations of vegetation or possible contaminants, and we are documenting the stormwater retention design interventions that the GCC is installing along the canal edge. This data is being used to search for unknown or unidentified pipes or sources of ground water entering the canal. Long-term this inquiry effort seeks to address the 300M gallons of untreated sewage that will continue entering the canal yearly even after the EPA finishes their clean-up of the toxic sediments at the bottom of the canal.

Another regional project is Grassroots Newark, focused on development and community issues on both sides of the Passaic River:

Just starting up is a New Town Creek monitoring project, where the first set of imagery was collected from the Riverkeeper boat. 

<a href="https://groups.google.com/forum/#!forum/tns_geoclub">The New School Geo Club</a> is a newly formed student group that has been active mapping occupation patterns in Washington Square Park among other sites.
