Which statement best describes the United States National Grid (USNG)?

• A. A presentation standard, expands the utility of street and other maps by adding several powerful features, can be used by private citizens, public agencies, and commercial enterprises
• B. A standard for weather prediction used by meteorologists only
• C. A set of legal guidelines for land use planning
• D. An aviation navigation protocol

Answer: (A)

US National Grid is a standardized way to describe locations on maps using a grid reference that works with street maps, GIS, and other map products. This system makes it possible for private citizens, public agencies, and commercial entities to share precise, unambiguous locations quickly, which is especially valuable in emergencies or coordinated operations. It expands the utility of maps by providing a common framework for conveying where something is, across different map sources and platforms, and by enabling clear communication of coordinates, overlays, and scale. The other options don’t fit because USNG isn’t a weather prediction standard used by meteorologists, nor a set of legal guidelines for land use planning, nor an aviation navigation protocol.
