GPS coordinates reporting shall be in what format?

• A. Decimal degree format
• B. Degrees Minutes Seconds
• C. Radians
• D. Gradians

Answer: (A)

Coordinates are reported in decimal degree format. This means latitude and longitude are written as decimal numbers, with positive values for north and east and negative values for south and west. Decimal degrees are the standard because they map directly to most GIS systems, are easy to parse in software, and preserve precision simply by adding more decimal places. For example, 37.7749, -122.4194 represents a precise location in decimal degrees. While Degrees Minutes Seconds is traditional and readable for humans, it requires conversion for machines, which can introduce errors. Radians and gradians are not used for standard GPS reporting; they’re mathematical units used in other contexts, not for everyday geolocation data.
