WebThe TIN model represents a surface as a set of contiguous, non-overlapping triangles. Within each triangle the surface is represented by a plane. The triangles are made from a set of points called mass points. Mass points can occur at any location, the more carefully selected, the more accurate the model of the surface. WebAuthor Simon Giraudot. Many sensors used in GIS applications (for example LIDAR), generate dense point clouds. Such applications often take advantage of more advanced data structures: for example, Triangulated Irregular Networks (TIN) that can be the base for Digital Evelation Models (DEM) and in particular for the generation of Digital Terrain …
