standards; Arizona plane coordinate system

SB 1756 updates Arizona's geospatial coordinate system terminology and standards. It changes the official name from "Arizona coordinate system, 1983" to "Arizona plane coordinate system" and defines three geographic zones covering all Arizona counties (west, central, and east). The bill mandates that all land descriptions, surveys, and geospatial documents must explicitly state "Arizona plane coordinate system, 1983, [zone name]" and include specific metadata like the national reference frame and epoch date. It also requires strict adherence to national geodetic standards for coordinates and prohibits any modifications to the system. This directly affects surveyors, land developers, and government agencies creating or using geospatial data in Arizona.
