The coordinate system origin of a local datum is not at the center of the earth. The center of the spheroid of a local datum is offset from the earth's center. NAD and the European Datum of (ED ) are local datums. NAD is designed to fit North America reasonably well, while ED was created for use in Europe. The North American Datum of is based on a newer defined spheroid (GRS 80); it is an Earth-centered (or " geocentric ") datum having no initial point or initial direction. NOAA provides a converter between the two systems. .

We stayed after fighting in the Second World War. After Vietnam, too. We stayed because the city sounds like a war, and you can't leave a war once you've been you can only keep it at bay--which is easier when you can see and hear it near you, that fast metal, that constant firing around you, cars up and down the streets and freeways.
Although many of the vertical datum transformations between the North America Vertical Datum of (NAVD 88) and mean sea level, and between mean sea level and the other tidal datums, are based on tidal values from the present National Tidal Datum Epoch (NTDE, to ), some are based on data from older tidal epochs. More than 18 million nature lovers have chosen the Audubon Field Guides as their go-to nature reference.

In fact, there’s no book that does that. A vertical datum is a base measurement point (or set of points) from which elevations are determined.
Historically, the standard datum used by the federal government was the National Geodetic Vertical Datum of (NGVD 29). However, the North American Vertical Datum of (NAVD 88) is now the national standard.
Inthe datum was revised to include information from satellites (GPS). It remains the most accurate reference point for North America and is still in use by several government agencies.
