# Slope Classification (Design Aid)

# Slope Classification (Design Aid)

# Overview

The Slope Classification (Design Aid) displays the original terrain slope as color-coded gradient bands directly in the 2D view. This allows to quickly identify areas with steep slopes without having to run the full analysis. The feature can be used for **preliminary terrain assessment and earthwork planning** across a range of projects. It helps as a guide to identify steep areas, assess site suitability, and determine where **grading, cut and fill, or terracing** may be required.

# Workflow

Use the following workflow to quickly assess terrain and identify areas that may require earthwork:

1. In the **RHS Terrain property grid**, find Slope Classification (Design Aid).
2. Toggle the **“Show Slope Classification” to Yes**.

1. Click **Configure** to define the gradient bands.
2. Select a classification mode:
   - **Equal Interval:** Classify the terrain based on fixed slope ranges.
   - **Quantile:** Classify the terrain based on the distribution of the actual slope data.
3. Review the colored terrain in the 2D view.
4. Identify areas where the terrain exceeds the desired slope.

1. Draw a [Wall Line](https://mes100.com/docs/wall-lines/) at the desired terrace location and assign the required wall elevation.
2. Configure the slope degree if necessary. See [Wall Slope Template Configuration](https://mes100.com/docs/how-to-modify-slope-dimension/) to set the slope angle, slope ratio and other slope parameters.

# Known Limitations

## Single Wall Elevation

- Only a **single elevation can be defined for each Wall Line**.
- When the existing ground elevation varies along the Wall Line, the assigned wall elevation may not match the original ground level at all locations.
