![]() Virgin Islands, and Pacific Island territories, the vertical datum is typically referenced to local mean sea level. Vertical Datum: Typically the North American Vertical Datum of 1988 (NAVD88), although the National Geodetic Vertical Datum of 1929 (NGVD29) and local reference datums are used in some areas outside of the conterminous United States. For Hawaii, Puerto Rico, U.S. ![]() Horizontal Datum: The North American Datum of 1983 (NAD83) For this example, A is the primary datum, B is the secondary, and C is the tertiary datum. There are typically 6 degrees of freedom that need to be considered by the engineer before choosing which feature is A, B, or C. A trained engineer is required to run the software. The coordinate system and projection information for ALL DEMs are in each DEM file header GIS software should detect them automatically. Computer software can be purchased for dimensional analysis.Original Product Resolution (OPR) DEMs – projection varies.To improve the National Spatial Reference System (NSRS), NGS will replace all three North American Datum of 1983 (NAD 83) frames and all vertical datums, including the North American Vertical Datum of 1988 (NAVD 88), with four new terrestrial reference frames and a geopotential datum. 1-meter DEMs are in Universal Transverse Mercator (UTM). New Datums: Replacing NAVD 88 and NAD 83.5-meter DEMs (Alaska only) are Alaska Albers Equal Area.They are all in geographic coordinates (latitude/longitude). 1/3-, 1-, and 2-arc-second (also the discontinued 1/9-arc-second) DEMs are not projected.From single test method programs to our DATUM software packages, United product software is known for its versatility and ease of use.
