Course Description
The need for accurate, consistent and reliable height information is one of the most important set of attributes for any local, regional or national geodetic system. Planning for inundation and flood modeling, ecosystem risk assessment, civil engineering, topographic mapping and charting are vital elements of our national infrastructure. Vertical datums provide the foundation to which all of these activities can be related. This presentation explores the relationship between tidal and geodetic datums and the most general types of heights that are encountered and how they relate to each other. In addition, the presentation reviews how heights are determined and the National Ocean Service (NOS) VDatum transformation tool.
