Ground models (TIN)

InfoWorks WS Pro supports the use of a triangular irregular network (TIN) ground model to represent the ground surface in the area covered by your model. The ground surface is represented by triangles with known elevations at the triangle vertices.

InfoWorks WS Pro supports three TIN ground model formats:

Format File Suffix Description

Arc/Info TIN

NET

Use the UNGENERATETIN command with the NET option in Arc/Info to create a .NET file containing lists of nodes, edges and triangles.

This .NET file can then be imported into InfoWorks WS Pro.

ArcView and 3d Analyst

SHP

A TIN can be exported from ArcView as a Shapefile (SHP) using the 3D Analyst option.

This .SHP file can then be imported into InfoWorks WS Pro.

InfoWorks WS Pro Internal

IIM

This is the internal format used by InfoWorks WS Pro. When importing other file types they are converted to this format before use.

The format is not published. You cannot directly edit the TIN in this format. However, you can export a ground model to an IIM file for subsequent import to another database or model.
