Abstract:

This study evaluates Height Modernization issues related to NGS hybrid geoid performance (specifically GEIOD09 and GEOID03) for height conversions between NAVD88 and NAD83 for the state of Ohio and quality of gravity and height data needed to produce a cm-accurate gravimetric geoid. The hybrid geoid is of particular significance in this study, because an accurate hybrid geoid would support both accurate height conversions as well as improve orthometric (MSL) height determination, facilitating the almost-total replacement (except in GPS-antagonistic environments) of traditional leveling exercises by GPS leveling, a much more cost- and labor-efficient heighting technique than its traditional counterpart.
