CST Level 1 Land Surveyor Certification Practice

What does NGS stand for?

1. National Geodetic Survey

2. National Geographic Society

3. Natural Geology Survey

4. National Grid System

The correct answer is: National Geodetic Survey

The correct answer refers to the National Geodetic Survey, which is a scientific agency of the National Oceanic and Atmospheric Administration (NOAA). The primary function of this agency is to define, maintain, and distribute the National Spatial Reference System, which provides reference points for mapping and surveying throughout the United States. This system is essential for various applications, including engineering, construction, and land surveying, as it ensures consistent geographic coordinates. The other options, while they may seem relevant, do not accurately capture the purpose or function associated with the acronym NGS in the context of land surveying. The National Geographic Society is focused on geography and exploration, primarily in publishing and education, rather than geodetic survey work. The term Natural Geology Survey is not a recognized agency or program and could confuse with geological surveys, which are distinctly different. Lastly, the National Grid System refers to a method of geographic organization rather than a specific surveying agency, which establishes a grid for spatial reference but does not fulfill the role of establishing geodetic control points like the NGS.
