He was to mark the boundaries of every county, barony, civil parish, and townland in tandem with the first Ordnance Survey of Ireland.
He was also called upon to assist in the preparation of a Parliamentary bill to provide for the general valuation of Ireland.
This act was passed in 1826 and Griffith was appointed Commissioner of Valuation in 1827, but did not start work until 1830 when the new 6-inch Ordnance Survey maps required by the statute became available.
Griffith served as Commissioner until 1868,[2] when he was succeeded by Sir John Ball Greene, who took charge of the ongoing revisions of the valuation on an annual basis.
Many of these records were also digitised and made readily available to the public online as part of the Ask about Ireland and Cultural Heritage Project initiative.
