Fundamentals of Surveying (FS) Practice Exam

What does the term 'projected' indicate in the state plane coordinate system?

1. The survey is inaccurate and needs to be corrected

2. Handwritten coordinates are entered into computer software

3. Survey points need to undergo a unit conversion

4. The Earth's curvature is accounted for in survey calculations

The correct answer is: The Earth's curvature is accounted for in survey calculations

In the context of the State Plane Coordinate System, the term 'projected' refers to the method by which the curved surface of the Earth is represented on a flat plane. This involves the use of mathematical projections to translate three-dimensional coordinates into two-dimensional coordinates that can be used for surveying and mapping purposes. By accounting for the Earth's curvature, survey calculations become more accurate for specific areas since the State Plane Coordinate System is designed to minimize distortion over particular zones. Each state or region may have its own projection tailored to its specific geographic characteristics, which ensures that the coordinates maintain a high level of accuracy for local surveying work. This projection process is fundamental in surveying because it allows surveyors to work with a coordinate system that is easier to manipulate while still retaining a close relationship to the real-world locations of points on the Earth's surface.
