TINs are a digital means to represent surface morphology. TINs are a form of vector-based digital geographic data constructed by triangulating a set of vertices points. The vertices are connected with a series of edges to form a network of triangles. The edges of TINs form contiguous, nonoverlapping triangular facets and can be used to capture the position of linear features that play an important role in a surface, such as a ridge line or stream course.

Because nodes can be placed irregularly over a surface, TINs can have a higher resolution in areas where a surface is highly variable and a lower resolution in areas that are less variable.

This allows a TIN to preserve all the precision of the input data while simultaneously modeling the values between known points. You can include precisely located features on a surface—such as mountain peaks, roads, and streams—by using them as input features to the TIN nodes.

There are different methods of interpolation to form these triangles, such as Delaunay triangulation or distance ordering. ArcGIS supports the Delaunay triangulation method. The resulting triangulation satisfies the Delaunay triangle criterion, which ensures that no vertex lies within the interior of any of the circumcircles of the triangles in the network.

A TIN expects units to be in feet or meters, not decimal degrees.

Delaunay triangulations are not valid when constructed using angular coordinates from geographic coordinate systems. TIN models are less widely available than raster surface models and tend to be more expensive to build and process.

The cost of obtaining good source data can be high, and processing TINs tends to be less efficient than processing raster data because of the complex data structure. 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.

In the past up until version 9. From SketchUp Pro you can then export to a other formats. If you are using ArcGIS 9. Let's say that it works best when source TIN is quite simple. One other problem is that spatial reference information is not preserved so even if you manage to get your TIN out of ArcGIS and you will need to manually georeference it.
