Over time, surveyors have gathered a massive collection of surface measurements to more reliably estimate the ellipsoid. Even if the features are horizontally referenced to NAD 83, this does not mean the vertical datum is a 3-D vertical datum. Information word has old French and middle English origins. 2.
