OASIS (from website):
The Open Accessible Space Information System (OASIS) website provides the richest source of community maps for New York City — free and all in one place. It helps nonprofits, community groups, educators, students, public agencies, and local businesses develop a better understanding of their environment with interactive maps of open spaces, property information, transportation networks, and more.
The OASIS website is guided by a collaborative partnership of private and public sector representatives that seek to sustain an accessible information system that helps enhance the stewardship of open space so these areas are linked, diverse and sustainable for the benefit of all people, organisms, and ecosystems in and around New York City.
Created to provide New York residents and community developers with more information about the activities and features of each community garden, this GardenMaps charts out the results of a 2009-2010 survey by Mara Gittleman and Lenny Librizzi to support the work of GrowNYC and GreenThumb.
