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.
