The State Plane Coordinate System (SPS or SPCS) is a set of 124 geographic zones or coordinate systems designed for what?

• A. Specific regions of the United States.
• B. Global navigation systems.
• C. Time zones around the world.
• D. Oceanographic zones.

Answer: (A)

The main idea behind the State Plane Coordinate System is to keep map distortions small by using many localized projections tailored to specific regions. Instead of one national projection, the United States is divided into about 124 zones, each with its own parameters so coordinates are very accurate for that area. This zoning lets surveyors describe parcels and align infrastructure with high precision within a zone, which is crucial for land records and engineering work. It’s not for global navigation, time zones, or oceanography, which is why the correct answer points to specific regions of the United States.
