Triangulated irregular network - Wikipedia
A TIN is a vector -based representation of the physical land surface or sea bottom, made up of irregularly distributed nodes and lines with three-dimensional coordinates that are arranged in a network of non-overlapping triangles.
What is a TIN surface?—ArcMap | Documentation - Esri
Triangular irregular networks (TIN) have been used by the GIS community for many years and are a digital means to represent surface morphology. TINs are a form of vector-based digital geographic data and are constructed by triangulating a set of vertices (points).

TIN（Triangulated Irregular Network）,也名“曲面数据结构”，是由Peuker和他的同事于1978年设计的一个系统，它是根据区域的有限个点集将区域划分为相连的三角面网络，三角面的形状和大小取决于不 规则分布 的 测点 的密度和位置，能够避免地形平坦时的 数据冗余 ...

不规则三角网（Triangulated Irregular Network，TIN） 是另外一种表示数字高程模型的方法，它既减少规则格网方法带来的数据冗余，同时在计算（如坡度）效率方面又优于纯粹基于等高线的方法。
We called our implementation of this approach a Triangulated Irregular Network or TIN (Peucker, et.al., 1975). There are two complementary approaches to the computer representation of a surface of triangular facets. One method gives primacy to the triangular facets themselves.
Triangulated Irregular Network - SpringerLink
2016年1月1日 · A Triangulated Irregular Network (TIN) is a special case of a Digital Elevation Model (DEM). A terrain can be mathematically modeled as a function z = f (x, y) mapping a point (x, y) in a domain D in the plane to its elevation value f (x, y). In practice, the value of function f is known at a finite set S of points within D.
