Datum conversion factor
WebIf metric units are desired, divide the Easting and Northing values in feet by 3.28 feet/meter. or in metric: 941,110 ft. ÷ 3.28 ft./meter = 286,850 meters. To determine a coordinate by yourself, it helps to have a map that depicts the State grid, at least as "tick marks" around the margin of the map. WebJan 29, 2024 · NGS Coordinate Conversion and Transformation Tool (NCAT) allows users to easily convert between different coordinate systems and/or transform between different reference frames and/or datums, in a single step. For coordinate conversion, NCAT allows conversion between lat/long/height, SPC, UTM, XYZ, and USNG systems.

WebThis map displays countywide conversion values to adjust elevations from the National Geodetic Vertical Datum 1929 (NGVD 29) to the North merican Vertical Datum 1988 (NAVD 88). Values indicated should be added to current NGVD 29 elevations (not displayed) to obtain the NAVD 88 elevation. Countywide values were calculated using the methodology WebTransformations between old datums (NAD27, Old Hawaiian, Puerto Rico, etc.) and HARN could combine uncertainties (that is, NAD27 to HARN equals 0.15 m + 0.05 m = 0.20 m). In near offshore regions, results will be less accurate but seldom in excess of 5.0 m. Farther offshore, NAD27 was undefined.

WebConversion between NAVD 88 and the commonly used National Geodetic Vertical Datum of 1929 (NGVD 29) varies spatially; however, over most of the study area the following conversion can be used: NGVD 29 = NAVD 88 – 3.5 feet. This conversion generally is accurate within about +/- 0.5 feet. The reader is directed to either the National Geodetic ...
