Geodesy
Geodesy is the science of measuring the size and shape of the earth and its gravitational field.
Some would also include the study of the Earth's magnetic field.
Geodesy is a suite of powerful Earth-observation techniques, associated methodologies, and analysis tools that today are making a vital contribution to science and society. Yet geodesy is not a new, child-of-technology science.
[geodesy] The science of deducing the size and shape of the earth by measuring its gravitational field.
What is Geodesy? - The Shape of the Earth
Now you might think at this point, "But what about all the hills, valleys, the mountain ranges, and the deep-sea trenches in the ocean. Surely they must contribute to the shape of the earth".
Geodesy Tools
The Geodesy tool allows users to interactively create great circles and rhumb lines. With Geodesy Calculator, users can specify two coordinates and generate a great circle route, a rhumb line, or a geodesic route.
Geodesy is "the branch of applied mathematics that determines the exact positions of points, and the shapes and areas of large portions of the earth's surface; the shape and sixze of the earth; and the variations of earth's gravity and magnetism.

An Overview of Geodesy and Geographic Referencing Systems
The magic of geographic information systems is that these tools can bring together and associate representations from diverse sources and infer relationships based on spatial references.

Geodesy, the science of the Earth's shape, tells us where the geoidal surfaces depart from the ellipsoid, which, worldwide, tend to range between about -100 to +70 m.
Geodesy is the study of the size, shape and motion of the Earth. It is used to calculate map projections, which are mathematical transformations used to represent a spherical surface on a flat map.

There is then a discussion of geodesy. This is followed by an introduction to projections and their classes (perspective, azimuthal, cylindrical and conic). The differences between tangent and secant projections are explained.
At the end of 1994, the Institute of Geodesy and Geo-Information was established on basis of Laboratory of Satellite Geodesy and Geo-Information.
NAD83 is based on the GRS80 ellipsoid, derived from satellite geodesy, whereas NAD27 uses the Clarke 1866 ellipsoid.

The study of this "more or less" is called geodesy, and its products are spheroids. Spheroids are mathematical representations of the true shape of the earth, from which calculations of location can be made. These calculations are called "datums." ...
Since a map is a representation, the original shape of the represented subject must first be defined. An important branch of cartography, geodesy studies the Earth shape and how it is related to its surface's features.
