Westchester County GIS

Established in the late 1980's, Westchester County Geographic Information Systems (GIS) develops, maintains and distributes geospatial data for Westchester County, New York. The program offers a wide range of online data as well as providing technical support to both local and county government agencies through highly trained and experienced staff. Today, many Westchester County GIS products and services are also integrated into and provide content for commercial and third-party applications.
 
Westchester County GIS pioneered development of the first countywide digital base map in 2000 which now provides the spatial foundation of the County's GIS program. Subsequent photogrammetric projects in 2004, 2007, and 2013 provided the basis for ongoing maintenance of strategic countywide orthophotograpy and large-scale planimetric datasets. Historic aerial photography, dating back to 1947, has also been made available in many online mapping applications.
 
Maintaining state-of-the-art computing and GIS facilities in White Plains, New York, Westchester County GIS staff utilizes the latest versions of the Environmental Systems Research Institute (ESRI) software for internet, desktop, and mobile applications, with Oracle as its database management system. Constantly evolving with new technologies, Westchester County GIS continues to maintain a broad countywide presence in government programs with current focus in the areas of critical infrastructure management, emergency response and public safety, land use and environmental planning, transportation and airport systems, County real estate and land records, and public health.
