Theming Surfaces to Analyze Height, Slope, and Aspect
You can create a theme to change the display of a surface based on height
(elevation), slope, or aspect (direction of slope).
IllustrationSurface Theme Type
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.
