In addition to analyses of
elevations,
slopes, and
slope arrows, you can perform the following types of analyses:
- Contours
- Contours can be used to analyze a surface. They can be color coded, and a legend table can be created that shows the area and/or volume that the contours represent.
- Directions
- With this type of analysis, you can see a visual representation of your surface slopes. For example, you can use it to see which parts of your surface flow to the south and which flow to the north.
- User-Defined Contours
- Contours are usually placed at even intervals, such as the 1' (0.5 meter) contours with which you have been working so far. What if you want to show a contour that represents elevation 92.75? That’s done as a user-defined contour. A user-defined contour is an individual instance of a contour, usually at an irregular interval.
- Watersheds
- A watershed analysis will outline areas within the surface where rainfall runoff flows to a certain point or in a certain direction. This type of analysis is yet another way of studying the drainage characteristics of the terrain.
