Atomic Polygons
Atomic polygons serve as a set of basic building blocks for generating the polygons of many of the district types represented in the NYC Street Centerline (CSCL) database. Feature classes such as election district, school district, census block, FDNY administrative company, and community district can be dissolved by combining the appropriate fields in atomic polygons. All previously released versions of this data are available on the DCP Website: BYTES of the BIG APPLE. Current version: 26b

Columns
Each source column, with the name and type we use to store it.
The publisher has not provided a data dictionary.
3 of 30 columns carry a concept; 29 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
