modernizing the New Hampshire coordinate system.

SB 560 updates New Hampshire's land surveying standards by formally adopting the National Geodetic Survey's (NGS) current coordinate system, replacing outdated terms like "New Hampshire coordinate system of 1927" and "1983." It requires all survey documents, maps, and land records to use the new "New Hampshire state plane coordinate system" (NHSPCS) defined by NGS, phasing out older systems by specific deadlines (1927 system no longer usable after 1989, 1983 system after NGS releases the new standard). This directly affects licensed land surveyors, government agencies, and anyone creating or recording land surveys or maps. The bill clarifies terminology, standardizes coordinate units (feet/meters), and mandates clear documentation of survey methods in public records.
