The geoid is the shape that the ocean surface would take under the influence of the gravity of Earth, including gravitational attraction and Earth’s rotation, if other influences such as winds and tides were absent. This surface is extended through the continents.

This is an interactive web site (based on Javascript) to visualize the Geoid and other gravity functionals of the Earth. Please have some seconds patience for generating the image on the server.

The geoid is a model of global mean sea level that is used to measure precise surface elevations. A depiction of the United States geoid. Areas in yellow and orange have a slightly stronger gravity field as a result of the Rocky Mountains. Do you have access to a 3D printer?

Simply pick the “Import from disk” in the geoid selection dialog when converting from/to a coordinate system. Doing so will open a dialog that will ask you to locate the proper geoid file. Proceed to select the downloaded desired Geoid and Zephyr will do the rest!

The geoid is a three-dimensional model representing the Earth’s surface if it were free of irregularities such as mountains or oceanic troughs, but only influenced by the gravitational field. It is used in geodesy and geophysics to measure height …

The geoid measures mean sea level and gravity. The GRACE and GOCE satellites are providing the most accurate measurements of the geoid to this date.

This is a repaired mesh from the file at https://oceanservice.noaa.gov/facts/geoid.html Prints great at .16 resolution. Great present for a surveyor or anyone in the geospatial field!
