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)

State Plane coordinates are built to provide accurate planimetric coordinates within defined parts of the United States. The system splits the country into many zones, and each zone uses a projection chosen to minimize distortion for that local area. That way surveyors can work in a flat plane, making precise distances, areas, and positions that align with legal property descriptions and engineering needs. It’s specifically about mapping and surveying in targeted regions of the U.S., not global navigation, time zones, or oceanography.
