NYCityMap
New York City government began using computer mapping in the late 1970s. Since then, DoITT's GIS unit has established a robust and versatile City basemap, with geo-referenced dated and associated tools called, NYCmap. This tool supports the online application NYCityMap, which provides the City's wealth of GIS information to the public, and also allows other city agencies to leverage this data to support City operations, analysis, policy making, and public safety.

In addition to indicating the specific building requested, users can select additional icons 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. This page is also a single access point to many of the location-based applications on NYC.gov such as online property, building, census, statistics and safety information for New York City.
