HabitatMap was started in 2006 in Brooklyn to document the links between the built environment of New York City neighborhoods and the health and well being of the people who live, work, and play in these neighborhoods. Now the site is open to participants and contributions from around the globe.
HabitMap is a community mapping and social networking website. Getting involved is easy. Simply identify something in your neighborhood that either enhances your quality of life, such as a local farmers market or public park, or is cause for concern, such as a historic building threatened by bulldozers or a contaminated property down the block, and add it to a Google Map.
You can also create your own Google Map highlighting a specific area of interest, embed maps on your website or blog, invite fellow activists to contribute to your maps, and discuss issues and recruit collaborators in the HabitMap forums.
