Theming Surfaces to Analyze Height, Slope, and Aspect
Concept Procedure Quick Reference
 
 
 

You can create a theme to change the display of a surface based on height (elevation), slope, or aspect (direction of slope).

Surface Theme Type Illustration
Height - Changes the display based on elevation.

 

 

 

 

 

 

 

 

Slope - Changes the display based on ground slope or steepness.

 

For example, you can use gray to show areas with a slope of less than 10%.

 

 

 

 

Aspect - Varies the display based on the direction of ground slope.

 

 

 

 

 

 

 

 

Create a theme on height to analyze the elevation data, a theme on slope to help you determine which areas are flat enough for developing houses, or a theme on aspect to help you find the best drainage routes.
