Height Modernization
Height Modernization is a series of activities designed to advance and promote the determination of elevations by GPS surveying, rather than by spirit leveling. It includes research and development activities seeking to improve the determination of geometric elevations by GPS surveys as well as activities seeking to improve the determination of geoid height. It includes activities leading to improved height determination both for the static surveyor and for the moving navigator.
