What is civil TIN?

TIN stands for triangulated irregular network. This kind of surface is made up of non-overlapping triangles. Each of the triangles represents a face on the surface.

What does TIN mean in surveying?

Triangular irregular networks (TIN) have been used by the GIS community for many years and are a digital means to represent surface morphology. TINs are a form of vector-based digital geographic data and are constructed by triangulating a set of vertices (points).
