If you do not understand ellipsoids and datum definitions, it is recommended you use the defaults. Use these settings to define the ellipsoid model that best approximates the curvature of the Earth's shape in the map region. The Ellipsoid group contains options for defining the ellipsoid. Parameters vary depending on the selected Conversion Method.
You can edit the conversion parameter and values directly by selecting the value you want to edit and typing a new value over it. If you select from the Ellipsoid Name list, you can specify your own ellipsoid model parameters. The Bursa-Wolfe method is similar to the Molodensky method, but in some instances it produces more accurate results because it takes into account both displacement and rotational differences between two ellipsoids.Ĭhoose None if the predefined methods do not suite your purpose. It does not take into account any rotational differences between the two ellipsoids.
It adjusts latitude and longitude coordinates by taking into account the displacement between two datum's ellipsoids on all three axes. The Molodensky method is the most widely used method of datum conversion. The conversion methods include Molodensky, Bursa-Wolfe, and None. The Conversion Method controls the method of datum conversion and the conversion parameters. Customize the parameters and values as needed. Select a datum to populate the Parameter and Value columns. The Datum list contains predefined datums. Use the Datum group to define a custom datum and specify the exact datum parameters and values.
