The National Geodetic Vertical Datum 1929. The vertical control datum, formerly known as the Sea Level Datum of 1929, established for vertical control in the United States by the general adjustment of 1929.

Mar 19, 2015 · 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 1929 (NGVD 29). However, the North American Vertical Datum of 1988 (NAVD 88) is now the national standard.

in NGVD 29. For example, the difference between the two measuring standards in Lake Okeechobee is 1.25 feet, so a water level of 12.5 feet NGVD 29 is 11.25 feet NAVD 88. This variation affects only the numerical value for the elevation point. The volume and depth of water remains the same. Q: Are water level gauges calibrated to NAVD 88?
