Access to Geospatial or location-based information and data is provided to the public through NYCityMap and the Go there. NYCityMap is targeted towards non-mapping professionals and provides a wealth of geographic-based information from the input of a single location. In addition to indicating the specific building requested, users can select additional layers to add to the map such as schools, day care centers, senior centers, libraries, hospitals and more as well as links to Web sites for these facilities. NYCityMap also provides access to many additional the location-based applications on NYC.gov such as tax map, street closures, census, and zoning and land-use (ZoLa). To access these applications click ‘Other Map Themes’ in the top right.
New York City government began using computer mapping in the late 1970s. The Department of City Planning was the first using a computer mapping system from Synercom Technologies running on a DEC. In 1995, the Department of Environmental Protection agreed to fund the creation of a Citywide photogrammetric basemap. The need for the basemap sprung from its interest in developing a GIS databse of the NYC water and sewer infrastructure. At the time there was no single accurate basemap from which to register the sewer and water infrastructure and so was born the planimetric basemap.
In January 2000 a GIS unit was established within the Department of Information Technology and Telecommunications to host and maintain the City basemap since called NYCMap. Additionally, the group was tasked with providing data and geospatial services to City agencies and the public.
The mission of the DoITT GIS/mapping unit is to maintain and support an accurate digital map and geo-referenced data of New York City and develop tools, services and applications upon the data to better leverage and expose this investment. Geospatial data is used throughout NYC government. Geospatial data is supports City operations, planning, data analysis, policy making and public safety.
The GIS unit also maintains hosting environments for Internet and intranet applications. The Internet environment is for hosting public-facing applications for publishing data and information on City services, facilities, events and infrastructure. NYCityMap is a prime example of this.
