NAD83 (North American Datum 1983)
NAD83 (North American Datum 1983) is a precise coordinate system used to locate points on Earth's surface, primarily in North America. It provides a common framework for maps, GPS, and geographic data by referencing positions relative to the Earth's center of mass. NAD83 ensures that geographic information aligns accurately across different maps and technologies. It’s designed to be consistent and stable, accommodating the Earth's slight movements over time, which helps in navigation, land surveying, and mapping applications. Essentially, NAD83 acts as a standard reference to accurately describe locations across North America.
