Navigating Heights - The Role of Geoid Models in Modern Surveying

The Geoid, we’ve probably all heard this term before. But do we fully understand what it is, how it’s created, why and when we need to use one and the error introduced by not using one or even the error introduced by using one properly?

Check out my latest video on Geoid models, this may be review to most of the surveyors here but it's possible this could help clear up some fuzzy areas for that new crew chief on your team.
