Tidal datums are often the reference for shoreline or coastal property boundaries where an elevation related to local sea level is needed. Elevation values from maps using different vertical datums (e.g., NGVD 29, NAVD 88, MLLW, and MHHW) are not directly comparable because they are based on different frameworks and starting (or zero) points.

A) The elevation finder can help you find out the elevation of land for a country, place or other location. You can even figure out the land elevation below the sea or ocean. You can do this by typing in an address, name of a place, coordinates etc., into the corresponding input fields above.
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic system, vertical datum).
Mar 19, 2015 · As an example, using the table above for a location in Burlington County, if you have a first floor elevation of 6.0 ft (NGVD29) for a property, then the elevation in NAVD88 would be: 6.0 feet – 1.3 feet = 4.7 feet.
