How to visualize a slope analysis

Visualizing slope analysis is essential for understanding terrain characteristics. This article will show you how to create clear and informative slope maps using Pythagoras software. You'll learn to generate slope data from digital terrain models (DTMs), apply effective color schemes and add arrows that will effectively visualize the slope analysis.

Make sure you have a terrain model (DTM) in your Pythagoras drawing.

Create a Colorized Map based on Slope

When visualizing slope data, adding a color scheme is crucial for clarity and interpretability. Here are the steps to add this in Pythagoras.

STEPS

• Open the window DTM Properties.
  Click on the Name in the DTM Dropdown in Active Settings. Or via menu View > Display Options (CTRL + I), tab DTM, select the DTM and click on 'Properties'. 
• Check the option Show Colorized Map (1).
• Choose Slope from the dropdown (2)
• Click on the button Attributes (3). The window Color Map opens.
• Name your Color Map.
• Add and define the values manually and choose a color to display.

Visualizing the slope direction

To add the slope direction to a terrain model, you can use the command Slope direction (macro Bonus Tools).

STEPS

• For optimal visual control, create a new layer.
• Go to the menu Bonus Tools > DTM, select Slope Direction.
• In the window Select DTM, choose the terrain model for which the slope direction needs to be visualized.
• Click on the button 'OK'.

The slope direction is calculated. Arrow symbols are added to the drawing. You can set the layer with the arrows to visible or invisible.
