# Terrain visualization

## Terrain Visualization

The *Terrain Visualization* is used to verify that waypoints are all set above ground level. It can be toggled visible/hidden using the **T** button (next to the zoom +/- buttons shown above).

The indicator shows the altitudes of planned waypoints and the terrain:

* Circles indicate the altitude for each waypoint/pattern:
  * The green line indicates the *survey plan.*
  * The circles indicate the different points.

{% hint style="warning" %}
Red bars indicate below-ground waypoints!
{% endhint %}

***The legend for the circle text is given below:***

| **V**    | VTOL Takeoff waypoint |
