The Triangulated Surface toolset offers a set of surface analysis tools that operate on terrain, TIN, and LAS datasets. They provide the ability to extract surface properties, such as slope, aspect, and contour isolines, identify outliers in the data points, make volumetric computations, and create 3D feature classes that model the surface.

- Learn more about understanding slope
- Learn more about working with contours
The following list outlines the tools available in the Triangulated Surface toolset:
Creates a triangulated irregular network (TIN) dataset using a subset of nodes from a source TIN.
Creates 3D features by extruding each input feature between two triangulated irregular network (TIN) datasets.
Creates surface-conforming multipatch features by draping polygon features over a surface.
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.
Calculates the volume and surface area between a polygon of a constant height and a surface.
Creates polygon features that represent aspect measurements derived from a TIN, terrain, or LAS dataset surface.
Creates contour lines derived from a terrain, TIN, or LAS dataset surface.
Calculate the displacement between two surfaces to determine where one is above, below or the same as the other surface.
Creates polygon features that represent ranges of slope values for triangulated surfaces.
The following tools that were available in the 3D Analyst toolbox prior to version 10.0 have been deprecated and superceded by its counterpart listed in the Recommendation column:
Use the Surface Aspect tool to extract aspect information from a TIN surface.
Use the Surface Contour tool to extract contours from a TIN surface.
Use the Surface Difference tool to calculate the volumetric difference between two TINs.
TIN Polygon Volume
Use the Polygon Volume to calculate the volumetric and surface area between polygons of an input feature class and a TIN.
Use the Surface Slope to extract slope information from an input TIN.
