An overview of the Triangulated Surface toolset

Available with 3D Analyst license.

The Triangulated Surface toolset contains tools for identifying outlier measurements, generating contour lines, deriving slope measurements and computing aspect on terrain, TIN, and LAS datasets.

Tool	Description
Locate Outliers	Identifies anomalous elevation measurements from terrain, TIN, or LAS datasets that exceed a defined range of elevation values or have slope characteristics that are inconsistent with the surrounding surface.
Surface Aspect	Creates polygon features that represent aspect measurements derived from a TIN, terrain, or LAS dataset surface.
Surface Contour	Creates contour lines derived from a terrain, TIN, or LAS dataset surface.
Surface Slope	Creates polygon features that represent ranges of slope values for triangulated surfaces.
