The OASIS website was redesigned by the CUNY Mapping Service at the Center for Urban Research. In particular, David Burgoon completely reprogrammed and recoded the site to create a powerful but easy to use application, one that can be relatively easily extended and modified. He identified and integrated the best and most helpful aspects of several open source applications (more on that below) with ESRI software in creative and pathbreaking ways. Two people who've been involved with OASIS from its inception -- Christy Spielman and Steven Romalewski -- redesigned the website and maps. Christy helped develop the cartographic design of the map layers, created several of the website's graphic elements and navigation tools, and provided invaluable guidance and insights.  Steve updated the data sets, worked with Christy on the cartography, and guided the overall effort. Throughout this process we worked closely with other OASIS steering committee members and other OASIS website users who provided great feedback.

The work was supported financially by several sources, including a major gift to the Graduate Center from the Double-R Foundation, grant support from the USDA Forest Service, US EPA (through the New England Interstate Water Pollution Control Commission, and the Wildlife Conservation Society, and direct support through CUNY and the Graduate Center.  If you'd like to help us continue to provide this valuable mapping service, please consider making an online donation (select "OASIS Project/Center for Urban Research" as your designated donation).

OASIS has always been a collaborative partnership, and the newest version of the website features data and maps from new and long-standing partners (see our Wiki for more background). These include the Mannahatta Project at the Wildlife Conservation Society, the Stewardship Mapping Project of the USDA Forest Service, the US EPA's Harbor Estuary Program and the US Army Corps of Engineers, and the Council on the Environment of NYC community gardens program.

ESRI's New York City office -- in particular, Patrick Gahagan -- helped create the new look of the OASIS maps. Patrick developed the ArcGIS techniques we used to create the map of subway stations and routes, and also provided a terrain model database (DEM mosaic) that we used as a backdrop for the new OASIS map.

The new version of OASIS would not be possible without great improvements to ESRI's GIS software plus the emergence of production-level open source applications.  We used a combination of ESRI's ArcGIS Server (and ArcSDE running on Microsoft's SQL Server database engine), the open source map viewing library OpenLayers, and the JavaScript web framework Ext JS. We first used this combination of web mapping tools and techniques for the Long Island Index interactive map, and we plan to continue to enhance both applications with feedback from users of each website.
