Which two units of measurement are utilized in N.A.D. 83?

N.A.D. 83, or the North American Datum of 1983, is a geodetic datum used for mapping and surveying in North America. It is based on a three-dimensional ellipsoidal model of the Earth and is primarily employed for the precise determination of geographic coordinates.

The correct choice of meters and feet is significant because these units are commonly used in surveying and mapping applications. Meters are part of the metric system and are standard in many scientific applications, while feet represent the imperial system, which is still widely used in the United States for surveying purposes. This dual usage of measurement units provides flexibility depending on the context and audience of a particular survey or mapping project.

Utilizing both meters and feet allows surveyors to communicate and present information effectively to different stakeholders who may prefer one system over the other. The inclusion of both units enhances versatility in land surveying practices within the scope of N.A.D. 83, making it practical for various applications whether in engineering, construction, or land management.
