What is the required accuracy of a state plane coordinate system?

The required accuracy for a State Plane Coordinate System is typically defined as 1 part in 10,000. This level of accuracy is essential for ensuring that mapping and surveying work can be done effectively for various applications, such as land use planning, property surveys, and infrastructure development.

State Plane Coordinate Systems are designed to provide high precision within specific areas, allowing for accurate positioning and measurement of geographic data. The accuracy of 1 part in 10,000 means that for every 10,000 units of measurement, there could be an error of no more than one unit. This precision is vital for local and state-level applications, where small discrepancies can lead to significant impacts on planning and decision-making.

The other levels of accuracy listed, such as 1 part in 1,000, 1 part in 100,000, and 1 part in 1,000,000, do not meet the established standard necessary for the precision required in State Plane systems, which is why they are not the correct choice. Higher accuracies (like 1 part in 1,000,000) would be excessively precise for most practical applications and increase costs without significant benefit, while lower accuracies (1 part in 1,000 or
