An overview of the Raster Surface toolset

Available with 3D Analyst license.

With the Surface tools, you can quantify and visualize a terrain landform represented by a digital elevation model.

Starting with a raster elevation surface as input, with these tools, you can gain information by producing a new dataset that identifies a specific pattern within an original dataset. You can derive patterns that were not readily apparent in the original surface, such as contours, angle of slope, steepest downslope direction (Aspect), and shaded relief (Hillshade).

Each surface tool provides insight into a surface that can be used as an end in itself or as input into additional analysis.

Tool	Description
Aspect	Derives aspect from a raster surface. The aspect identifies the downslope direction of the maximum rate of change in value from each cell to its neighbors.
Contour	Creates a line feature class of contours (isolines) from a raster surface.
Contour List	Creates a feature class of selected contour values from a raster surface.
Contour with Barriers	Creates contours from a raster surface. The inclusion of barrier features allows you to independently generate contours on either side of a barrier.
Curvature	Calculates the curvature of a raster surface, optionally including profile and plan curvature.
Cut Fill	Calculates the volume change between two surfaces. This is typically used for cut and fill operations.
Hillshade	Creates a shaded relief from a surface raster by considering the illumination source angle and shadows.
Slope	Identifies the slope (gradient, or rate of maximum change in z-value) from each cell of a raster surface.
