NAVD88 is a correction of thousands of control points of elevation datum VDatum is a free tool by NOAA to transform data among a variety of tidal orthometric and ellipsoidal vertical datums Users can convert their data from different horizontalvertical references into a common and desired reference level Surveyors use a Fischer level at Glen Canyon in 1921 NOAA In 19th century America the expansion of the railroad famously led to the creation of our modern time zones imposing temporal order on a nation that to that point set time by dozens of local high noons NAVD88 was adopted as the official vertical datum in the National Spatial Reference System NSRS for the conterminous United States and Alaska in 1993 It is a tidal datum defined by the mean water level at the tide gauge in Rimouski Québec propagated over land using geodetic levelling The vertical datum is accessible at benchmarks In summary NAVD88 is still valid some BMs are still good according to published values some have to be updated from timetotime and their present elevations are indeed published by NGS Frequently Asked Questions Datums Datums National Geodetic Survey UNDERSTANDING NAVD 88 AND NGVD 29

reference for elevation measurements across North America It connects the height of land and water surfaces to a consistent baseline serving as a foundation for mapping and surveying NAVD88 is closely tied to ellipsoids and geoids providing a standard for how elevations are calculated relative to A vertical datum is a reference system used by surveyors engineers and mapping professionals to measure and relate elevations to the Earths surface Web VDatum is designed to vertically transform geospatial data among a variety of tidal orthometric and ellipsoidal vertical datums allowing users to

Alabama Alaska Arizona Arkansas California Colorado How do we convert the vertical datum from NAD1983 to ResearchGate The North American Vertical Datum of 1988 NAVD 88 is a geodetic reference system used for measuring elevations in North America It replaced the older National Geodetic Vertical Datum of 1929 NGVD 29 and provides a standardized framework for mapping and surveying projects North American Vertical Datum of 1988 NAVD 88 Have you ever noticed the abbreviation NAVD 88 or NGVD 29 written after an elevation marker on a survey or construction drawing and wondered what it means Whats the difference between the two Or maybe youve wondered why we dont always use Above Ground Level AGL Well there are a few simple explanations to answer why we need and use these complex systemsNAVD 88 is the The geopotential difference between NAVD88 and AHD systems came out as 968 051 m2s2 and the corresponding vertical shift 974 51 mm The differences between the other LVDs treated are very
