Height Modernization

The National Height Modernization Program enables access to accurate, reliable, and consistent heights. Elevation information contributes to informed decision making and impacts a wide range of important activities including mapping and charting, flood risk determination, transportation, land use and ecosystem management.

Height Modernization Program National Plan

The National Height Modernization Program has developed a strategic plan (available online) to help achieve the program's goals and priorities. Basic elements of Height Modernization support NGS's vision of a modernized geospatial reference frame and aim to prepare the user community before, during, and after implementation of the new vertical datum. In these ways, the Height Modernization Plan is closely aligned with the current NGS Ten-Year Plan (available online).
