![]() Associated with three-dimensional data ( x, y, and z) and topography, TINs are useful for the description and analysis of general horizontal ( x and y) distributions and relationships.ĭigital TIN data structures are used in a variety of applications, including geographic information systems (GIS), and computer aided drafting (CAD) for the visual representation of a topographical surface. The vertices of these triangles are created from field recorded spot elevations through a variety of means including surveying through conventional techniques, Global Positioning System Real-Time Kinematic (GPS RTK), photogrammetry, or some other means. A triangulated irregular network ( TIN) is a representation of a continuous surface consisting entirely of triangular facets (a triangle mesh), used mainly as Discrete Global Grid in primary elevation modeling.
