Abstract

VDatum is a free software tool being developed jointly by NOAA's National Geodetic Survey (NGS), Office of Coast Survey (OCS), and Center for Operational Oceanographic Products and Services (CO-OPS).

VDatum is designed to vertically transform geospatial data among a variety of tidal, orthometric and ellipsoidal vertical datums -

Title: Vertical Datum Transformation
Short Name: vdatum
Status: Completed
Publication Date: 2015-12
Abstract:

VDatum is a free software tool being developed jointly by NOAA's National Geodetic Survey (NGS), Office of Coast Survey (OCS), and Center for Operational Oceanographic Products and Services (CO-OPS).

VDatum is designed to vertically transform geospatial data among a variety of tidal, orthometric and ellipsoidal vertical datums -
Purpose:

VDatum allows users to convert their data from different horizontal/vertical references into a common system and enabling the fusion of diverse geospatial data in desired reference levels.
Notes:

1545
Supplemental Information:

VDatum software is written in Java so it runs on Mac OS X, Unix, VMP and Windows.

Where available and uncertainties are established, VDatum supports the conversions among following:

Coordinate Systems: Geographic, UTM, State Plane Coordinates (SPC), and geocentric (ECEF).

Horizontal Datums: NAD27, NAD83 (1986), and NAD83 (HARN); and ellipsoidal datums such as of ITRF, WGS84 and NAD83 serializations;

Vertical Datums:

(1) Ellipsoidal Datums: NAD83, WGS84, ITRF88, ITRF89, ITRF90, NEOS 90, PNEOS 90, ITRF91, ITRF92, SIO/MIT 92, ITRF93, ITRF94, ITRF96, ITRF97, IGS97, ITRF2000, IGS00, IGb00, ITRF2005, IGS05, ITRF2008, IGS08, WGS84 (transit), WGS84 (G730), WGS84 (G873), WGS84 (G1150), NAD83(PACP00), NAD83(MARP00);

(2) Orthometric Datums: NGVD29 and NAVD88;

(3) Tidal Datums: MLLW, MLW, LMSL, DTL, MTL, MHW, and MHHW;

(4) IGLD85

GEOID models: GEOID12A, GEOID09, GEOID06 (Alaska only), GEOID03, GEOID99, and GEOID96;

Supported file format: text (ASCII), LiDAR (.LAS) version 1.0 to 1.2, ESRI ASCII Raster (.ASC)
