This bill aims to modernize and clarify the legal framework governing New Hampshire's coordinate systems used in land surveying and mapping. It formally adopts the most recent coordinate system released by the National Geodetic Survey (NGS), referred to as the "New Hampshire state plane coordinate system" (NHSPCS), and updates relevant terminology. Key changes include the insertion of new definitions and restrictions on the usage of previous coordinate systems, specifically the New Hampshire coordinate system of 1927 and 1983. The bill specifies that these older systems should not be used for projects commenced after the NHSPCS has been released for public use.

Additionally, the bill amends existing laws to ensure that any coordinates defining land boundaries must be accompanied by a statement from a licensed land surveyor regarding their basis and the survey method used. It also establishes that the terms related to the coordinate systems can only be used in accordance with the definitions provided in the bill. The effective date of the act is set for June 19, 2026.
