Building footprints represent the full perimeter outline of each building as viewed from directly above. Footprints are digitized via the planimetrics update every 4 years and then maintained daily by DoITT GIS data editors.

Citywide Street Centerline (CSCL) is a multilayer database designed to support multiple agency operations, including emergency 911 dispatching systems. CSCL is maintained daily by the Centerline Management team at DoITT and Department of City Planning (DCP). Layers from this database support several derived products such as DCP’s Geosupport (City’s geocoder). The following datasets from the CSCL database have been made available to the public.

Address Points
The data represent visually identifiable and Borough President assigned addresses within NYC. Placement of the address points are approximately five feet within the respective building footprint along street front the address is assigned.

Planimetric mapping is the capture of geographic features from aerial imagery that are traditionally mapped to two dimensions. Planimetric data layers include features such as building footprints, curb lines, roadbeds, parks, and more. Since 2000, planimetric datasets have been captured every 4 years and are currently used to make up the City’s basemap.
