Geodetic CRS: JAD69
Datum: Jamaica 1969
Ellipsoid: Clarke 1866
Prime meridian: Greenwich
Data source: EPSG
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.
Revision date: 2023-11-19
Scope: Transformation of coordinates at 1m level of accuracy.
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.
Method: Coordinate Frame rotation (geog2D domain)
Area of use: Jamaica - onshore.
Description: (-33.722, 153.789, 94.959, 8.581, 4.478, -4.54, 8.95)
