Create a TIN surface

Available with 3D Analyst license.

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. It can be quickly generated in ArcGIS Pro by using the Create TIN tool. Follow these steps to generate a TIN in ArcGIS Pro.

Create a TIN

  1. On the Analysistab, click the Tools button. The Geoprocessing pane appears.
  2. Type Create TIN in the search box, and press the Enter key to search for the tool.
  3. Double-click Create TIN to open the tool.
  4. 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, which represents different surface features. You can add vector data using the Create TIN and Edit TIN tools. Use the Create TIN geoprocessing tool to construct a new TIN on disk. Once the TIN is created on disk, use the Edit TIN geoprocessing tool to add additional vector data to the new TIN. For more information on editing TINs, see Edit data contributing to a TIN.

Create a TIN from another source

A TIN surface can also be created from a raster, terrain dataset, or LAS dataset. To convert a raster dataset to a TIN, use the Raster To TIN geoprocessing tool. To convert a Terrain dataset to a TIN, use the Terrain To TIN geoprocessing tool. To convert a LAS dataset to a TIN, use the LAS Dataset To TIN geoprocessing tool.
