The United States National Grid (USNG) does not replace data storage formats for either Geographic Information Systems (GIS) or the State Plane Coordinate System (SPCS) for ______ applications.

• A. engineering and survey
• B. meteorology
• C. education
• D. healthcare

Answer: (A)

USNG is a simple, standardized way to express a location so people can communicate positions quickly in the field. It’s a coordinate reference system, not a replacement for how data are stored or managed in GIS or the State Plane Coordinate System. In engineering and surveying, precise data storage formats, metadata, units, and the established coordinate workflows are essential for design, measurement, and legal records. Those workflows rely on GIS-compatible formats and the SPCS framework to maintain accuracy and interoperability. Because of those precision and compatibility needs, USNG does not substitute for the data storage formats used in engineering and surveying.

Other fields might use USNG as a practical shorthand for locating places, but the critical point here is that for engineering and surveying, the formal data formats and coordinate systems remain indispensable.
