What is TIN surface?

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 is a TIN model?

Triangulated Irregular Network (TIN) is a 3D surface model derived from irregularly spaced points and break line features.

What are TIN files used for?

TINs are typically used for high-precision modeling of smaller areas, such as in engineering applications, where they are useful because they allow calculations of planimetric area, surface area, and volume.

What is DEM and TIN?

You know that TIN is a vector-based representation whereas DEM is represented as a raster from grid of squares. Actually TIN is a type of DEM and derived from the raster DEM. The TIN representation has information about altitude, slope and aspect and you can use them to extract the areas you require.

What does TIN stand for in GIS?

A triangular irregular network (TIN) layer is commonly an elevation surface that represents height values across an extent.

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.
