This is a companion dataset to PLUTO and MapPLUTO. PLUTO and MapPLUTO are created using the best available data from a number of city agencies. To further improve data quality, the Department of City Planning (DCP) applies changes to selected field values. DCPEdited is set to "1" in PLUTO if the record contains any changed values.

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.
