NGS Authors write technical guidelines, white papers, and scientific articles to educate and inform users on geodetic concepts and best practices for survey work and data processing with the goal of establishing high accuracy elevations. Publications thought to be of interest or relevant to Height Modernization are on this webpage, but also make sure to visit other NGS publications pages.
Non-NGS Authors also contribute publications that may be of interest to other investigators working in any fields related to Height Modernization. These scientific articles, white papers, and other publications are at the bottom of this page. Click here to view these publications.
