Which zone of the Arizona coordinate system has a scale set one part in ten thousand too small?

The correct answer identifies the Central zone of the Arizona coordinate system, which is known for having a scale factor that is set one part in ten thousand too small. This reduction in scale means that distances measured using this zone will yield values that are systematically shorter than the true distances. Understanding this aspect of the Central zone is crucial for land surveyors, as it can significantly impact the accuracy of surveys and the interpretation of mapped data.

When using the Arizona coordinate system for surveying, it is essential to be aware of how scale factors affect distance calculations. Different zones have unique characteristics, and recognizing that this specific flaw exists in the Central zone allows surveyors to make necessary adjustments or take extra precautions to mitigate potential errors associated with measured distances.

In contrast, other zones such as the West zone, East zone, and South zone do not exhibit this same scale-related issue, allowing for more straightforward application of measurements without the need for compensatory calculations. Thus, the Central zone stands out in this context, highlighting the importance of knowing the specifics of each zone within the Arizona coordinate system for effective surveying practices.
