Navigating Heights - The Role of Geoid Models in Modern Surveying

Описание к видео 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? In this video we attempt to answer all of these questions so stick around because as you'll see, the error by not knowing how to properly use a geoid when land surveying can be very costly.
