For the purpose of more precisely defining said system:\n1. The Massachusetts Coordinate System, NAD, 1983, Mainland Zone, Federal Zone Code M2001, is a Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 41° (degrees) 43′ (minutes), and 42° (degrees) 41′ (minutes), along which parallels the scale shall be exact. The origin of coordinates is at the intersection of meridian 71° (degrees) 30′ (minutes), west of Greenwich and the parallel 41° (degrees) 00′ (minutes), north latitude. This origin shall have the coordinates: North (Y) = 750,000 meters and East (X) = 200,000 meters.\n2. The Massachusetts Coordinate System, NAD 1983, Island Zone, Federal Zone Code I 2002 is a Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 41° (degrees) 17′ (minutes) and 41° (degrees) 29′ (minutes), along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian, 70° (degrees) 30′ (minutes), west of Greenwich and the parallel 41° (degrees) 00′ (minutes), north latitude. This origin shall have the coordinates North (Y) = 0 meters and East (X) = 500,000 meters.","path":["Part I","Title XV","Chapter 97"],"source_url":"https://malegislature.gov/Laws/GeneralLaws/PartI/TitleXV/Chapter97/Section12","current_through":"amendments passed before May 31, 2026","vintage":"","retrieved_at":"2026-09-17T05:22:14Z","sha256":"b94b0babd6205e832bc1f2fa673cafd5ab0ea98a5084662d20956dd4d6c50131","source_id":"us-ma","stale":false,"prev":"us-ma/mass.-gen.-laws-ch.-97-11","next":"us-ma/mass.-gen.-laws-ch.-97-13"},"notice":"GroundRules: Original legal text.
