You can gain additional information by producing a new dataset that identifies a specific pattern within an original dataset. Patterns that were not readily apparent in the original surface can be derived such as contours, angle of slope, steepest downslope direction (aspect), shaded relief (hillshade), and viewshed.
For additional information on each of these analysis functions, see the following links:
Learn more about creating contours
Learn more about calculating slope
Learn more about determining aspect
Learn more about producing a hillshade
Learn more about understanding cut/fill volumetric analysis
Learn more about performing a viewshed analysis
The following lists the tools in the Raster Surface toolset with a brief description of each. Each tool provides additional 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. |
Contour | Creates contours or isolines from a raster surface. |
Contour List | Creates contours or isolines based on a list of contour values. |
Curvature | Calculates the curvature of a raster surface, optionally including profile and plan curvature. |
Cut/Fill | Calculates cut and fill areas. |
Hillshade | Computes hillshade values for a raster surface by considering the illumination angle and shadows. |
Observer Points | Identifies exactly which observer points are visible from each raster surface location. |
Slope | Derives aspect from a raster surface. |
Viewshed | Determines the raster surface locations visible to a set of observer features. |
