The central zone of the Arizona coordinate system includes which of the following counties?

The correct answer identifies that the central zone of the Arizona coordinate system includes Coconino, Maricopa, and Pima counties. This alignment is crucial for land surveying as the Arizona coordinate system is designed for mapping and establishing control points across the state.

Coconino County is situated in the north-central part of Arizona and contains areas that are impacted by the geographic features unique to this zone, including significant elevation changes and wide-open spaces. Maricopa County, which encompasses Phoenix, the state capital, is central to many land surveying operations due to its urban development and infrastructure. Pima County, located in the southern central part of the state, includes Tucson, which is another major urban area relevant to the coordinate system.

Understanding these counties is vital for surveyors as they work within the central zone. This knowledge aids in the accurate measurement of land and the establishment of boundaries, which can affect legal, commercial, and residential activities in these areas. The central zone facilitates consistency and accuracy across these populous regions, ensuring that surveyors can effectively communicate and share data.

The relevance of the other counties in the alternate choices informs the division of the state’s coordinate system, as they may belong to different zones, each with its own geographic and survey-related characteristics
