geoidimalleja

Geoidimalleja is a theoretical concept in geodesy that attempts to describe a simplified model of the Earth's geoid. The geoid itself is a complex, irregular surface that represents the mean sea level extended globally, under the influence of gravity and rotation. It is an equipotential surface, meaning gravity is constant at all points on the geoid.

A geoidimalleja, as a simplified representation, aims to capture the essential characteristics of the geoid without its minute undulations. This might involve using mathematical functions to approximate the geoid's shape over large regions or for specific applications where extreme precision is not required. These simplified models can be useful for educational purposes or in scenarios where computational efficiency is paramount.

The development of geoidimalleja could involve techniques such as spherical harmonics or other numerical methods to smooth out fine-scale gravity variations. While the true geoid is essential for accurate height determination and understanding Earth's gravity field, geoidimalleja serves as an accessible approximation. Its existence and form are purely hypothetical, designed to illustrate the concept of a simplified geoid.
