JAD69 / Jamaica National Grid

Jamaica - onshore. , accuracy 1.0 m, code 15927 (default) [7]
Jamaica - onshore. , accuracy 2.0 m, code 1085 [3]
Jamaica - onshore. , accuracy 5.0 m, code 1084 [3]

Jamaica - onshore., accuracy 1.0 m, code 1086 (deprecated) [7]

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Derived at 4 stations, tested at a further 9. Also used as tfm to JAD69 to JAD2001 (see code 15926). Note: Info source paper contains an error in sign of dS, subsequently confirmed by primary author and NLA of Jamaica, and corrected in this record.

Information source: "GPS Coordinate Transformation Parameters for Jamaica", Newsome and Harvey, Survey Review Volume 37 Number 289 (July 2003), but with an error in sign of dS confirmed by author and NLA.
