Which counties are included in the Arizona coordinate system's west zone?

The Arizona coordinate system is essential for land surveying as it provides a standardized framework for mapping and geographic data collection across the state. In this system, the counties that fall within the west zone are La Paz, Mohave, and Yuma.

This classification is based on how the coordinate system divides the state into different zones to accommodate the geographic variations across Arizona. La Paz County, which is adjacent to California and the Colorado River, along with Mohave and Yuma counties, situated in the northwestern part of the state, share similar geographic and topographic characteristics that warrant their inclusion in the west zone. This zone allows surveyors to utilize a common reference system to enhance accuracy and consistency in mapping and construction projects across these areas.

Understanding the specific counties that comprise the different zones, such as this west zone, is crucial for professionals in land surveying as it affects how they may collect data, conduct surveys, and interpret measurements within Arizona's unique geographic landscape.
