Why do archaeologists use a datum point rather than simply measuring from the ground surface?
Archaeologists use a datum point to establish a consistent reference point for all measurements during excavations. This helps ensure accuracy and precision in recording the vertical and horizontal positions of artifacts and features. By having a fixed point of reference, archaeologists can maintain spatial relationships within the site.
What is datum in land survey?
A datum in land surveying is a known point or elevation used as a reference when measuring and mapping the land. It serves as the basis for establishing the positions of other points, helping to ensure accuracy and consistency in surveying work. Common datums include the North American Datum (NAD) and the World Geodetic System (WGS).
What is a datum point in drawing?
We have to make some choices when we dimension a block with a notch or cutout. It is usually best to dimension from a common line or surface. This can be called the datum line of surface. This eliminates the addition of measurement or machining inaccuracies that would come from "chain" or "series" dimensioning.
