Triangulated Irregular Network; a data format for representing surfaces as a connected network of triangles

Triangulated Irregular Network. A series of triangles constructed using elevation data points taken from coverages. These triangles are used for surface representation and display.

See digital terrain model - TIN Shape or configuration of the land surface or sea bottom.

triangulated irregular network. See digital terrain model -- TIN.

Triangulated irregular network. A surface representation derived from irregularly spaced points and breakline features. Each sample point has an x, y coordinate and a z value or surface value.

Triangulated Irregular Network. data structure, normally used in connection with terrain modeling, that describes a three-dimensional surface as a series of irregularly shaped triangles.

Triangulated Irregular Network; a variable resolution data structure for surface models, based on a Delaunay triangulation. It is based on a series of non-overlapping triangles which completely cover any surface.

Triangular Irregular Network. A surface representation derived from irregularly spaced sample points and breakline features having surface or z-values. Topological relationships between points and their proximal triangles are included.

A set of Digital Terrain Model (DTM) posts arranged in an arbitrary, non-gridded pattern.
