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.

What kinds of data can you use to create tins?

You can create a TIN surface from features, such as points, line, and polygons, that contain elevation information. Use points as spot locations of elevation data. Use lines with height information to enforce natural features, such as lakes, streams, ridges, and valleys.
