摘要

Earth scientists have always created spatial models of the subsurface. Before the dawn of computer-based modeling, earth models were simply drawn by hand on a piece of paper as cross-section or plan views, sometimes utilizing the techniques of descriptive geometry. These hand-drawn models are quick and easy to create; this is why we are still doing them on white boards, notebooks, and sometimes even on napkins. They communicate ideas very well, but they are subjective and rarely constrained by data in a measurable way. As the number of observations grew with the advancement of data collections technologies, it became a possible to use mathematical algorithms to do the modeling. These processes, first applied in two dimensions then in three dimensions, removed some of the subjectivity from the modeling. These processes work very well when the data density is high enough, meaning that models built with different mathematical methods are both realistic and similar one to another.
