Part 2/9:
In a recent educational resource from the National Society of Professional Surveyors in America, the webpage titled "Curvature Definitions for Land Surveyors" explained how surveyors include a correction of approximately 6 centimeters per kilometer to account for Earth’s curvature. This correction is standard practice, demonstrating an institutional acknowledgment of Earth’s roundness. If the Earth were flat, such corrections would be unnecessary, and surveyors would not adjust their measurements for curvature.
