Question

Quizplus · Accepted Answer

A TIN (Triangulated Irregular Network) is a digital data structure used in a geographic information system (GIS) for the representation of a surface. It is formed from triangles, which are created by connecting a set of points (vertices) in space, where each point has a three-dimensional position (x, y, and z coordinates). This method efficiently represents complex surfaces, allowing for precise terrain models.
