TIN (Triangulated Irregular Network) surfaces

A TIN (Triangulated Irregular Network) surface is a way of representing terrain or land elevation using a network of irregularly spaced triangles. Each triangle has three points with known elevation, and together they form a continuous surface that models the shape of the terrain. Unlike regular grids, TINs adapt their triangles to capture detailed variations in landforms, making them efficient for analyzing topography. This method is widely used in geographic information systems (GIS) for terrain modeling, landscape analysis, and engineering design, providing a precise and flexible way to visualize and analyze complex surface features.
