GIS data: A single line street base map representing the city's streets and other linear geographic features, along with feature names and address ranges for each addressable street segment. This dataset includes the Nodes file. The Nodes file contains a point feature and unique NodeID for each node that exists in the LION file. The Node_StreetName.txt file lists the street names associated with those nodes. Most nodes, representing intersections, will have at least 2 street names associated in the Node_StreetName.txt file.

All previously released versions of this data are available at BYTES of the BIG APPLE- Archive.

The LION Differences File (LDF) documents segment and node level changes that have occurred in the LION file between two subsequent releases. This file allows a user who "ties" organizational data to DCP's Segment ID and/or Node ID to migrate their data appropriately when these changes occur.

2020 Neighborhood Tabulation Areas (NTAs) are medium-sized statistical geographies for reporting Decennial Census and American Community Survey (ACS). 2020 NTAs are created by aggregating 2020 census tracts and nest within Community District Tabulation Areas (CDTA). NTAs were delineated with the need for both geographic specificity and statistical reliability in mind. Consequently, each NTA contains enough population to mitigate sampling error associated with the ACS yet offers a unit of analysis that is smaller than a Community District.

Though NTA boundaries and their associated names roughly correspond with many neighborhoods commonly recognized by New Yorkers, NTAs are not intended to definitively represent neighborhoods, nor are they intended to be exhaustive of all possible names and understandings of neighborhoods throughout New York City. Additionally, non-residential areas including large parks, airports, cemeteries, and other special areas are represented separately within this dataset and are assigned codes according to their type (See NTAType field). All previously released versions of this data are available at BYTES of the BIG APPLE- Archive.

The Department of City Planning (DCP) created Community District Tabulation Areas (CDTAs) to closely approximate the 59 Community Districts of New York City for the purpose of reporting American Community Survey (ACS) data. CDTAs are built by aggregating whole 2020 census tracts. All previously released versions of this data are available at BYTES of the BIG APPLE- Archive.
