1.To Create a Geoid Field file, choose the Global Geoid file, and then select a center and radius, or
•Geographic or Grid coordinate entry will be determined based on the coordinate type defined in your global geoid file.
•Pay special attention to the cardinal direction of geographic coordinates
2.Select a spacing for the field file to be interpolated extrapolate to.
•Geoid99 was created on a grid of 1 arc minute, or roughly 1800 meters. It is probably not necessary to expand or refine this spacing.
3.Select a Radius if using the Center and Radius method, and Save
)Save the Geoid file to the C:\GDP_Data\Geoid directory for easy transfer using data exchange. CSCS field files work under the same methodology, without the need to choose spacing, and instead save to a path C:\GDP_Data\CSCS.
