Create a TIN surface—ArcGIS Pro | Documentation

A triangulated
irregular network (TIN) surface can be generated from surface source measurements or by converting another functional
surface to a TIN surface. You can create a
TIN surface from features, such as
points, lines, and polygons, that contain elevation information.

Create a TIN

To create an empty TIN follow these steps.

1. Analysis

   tab, click the

   Tools

   button .

   On thetab, click thebutton

2. The

   Geoprocessing

   pane appears.

3. Type

   Enter

   to search for the tool.

4. Double-click

   Create TIN

   to open the tool.

5. Specify the parameters and click

   Run

   to build the TIN surface.

For more information on the TIN parameters, see the syntax section for the Create TIN geoprocessing tool.

You can create a TIN surface from one or more types of input data. You can also create it in stages, or you can add data to refine an existing TIN surface model.

TIN components are built from input vector data that represents different surface features. You can add vector data using the Create TIN and Edit TIN tools and use the Create TIN geoprocessing tool to construct a new TIN. Once the TIN is created, use the Edit TIN geoprocessing tool to add additional vector data to the new TIN. For more information on editing TINs, see TIN Editing Basics.
