4 results about "Triangulated irregular network" patented technology

A triangulated irregular network (TIN) is a representation of a continuous surface consisting entirely of triangular facets, used mainly as Discrete Global Grid in primary elevation modeling. The vertices of these triangles are created from field recorded spot elevations through a variety of means including surveying through conventional, Global Positioning System Real-Time Kinematic (GPS RTK), photogrammetry, or some other means. 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.
