# Terrain Visualization for Go To Location (GTL)

## Setting up your reference altitude during GTL (Go To Location) missions

### **Choose Your Altitude Reference** between:

* **Relative to Takeoff (RTL):** Measures altitude relative to the drone’s launch point.
* **Above Ground Level (AGL):** Adjusts altitude dynamically based on terrain variations.

* Access the detailed terrain profile graph to analyze elevation changes and compare the **Go To Location (GTL)** target elevation for precise and safe navigation.

### Pre Flight Caution Alerts and Warnings

**Caution Alerts and Warnings:** If the planned flight altitude exceeds limits or creates a conflict with the terrain, FlytBase provides an immediate warning, ensuring compliance with safety protocols.

{% hint style="warning" %}
Operators would be able to see an advance warning under the Terrain Profile Graph in case the flight path would come in close contact with the ground (within 20 meters) at any point when the Go To Location (GTL) point is selected. In this case a review of the flight path is strongly recommended.
{% endhint %}

{% hint style="warning" %}
Operators would be able to see an advance warning over the Terrain Profile Graph in case any point on flight path exceeds the maximum altitude limit specified for the drone in device settings when Go To Location (GTL) point is selected. In this case a review of the flight path is strongly recommended.
{% endhint %}

{% hint style="danger" %}
Operators would see a warning under the Terrain Profile Graph in case any point on the flight path is within collision proximity with the ground when the Go To Location (GTL) point is selected to mitigate the collision risk. In this case, you would need to redefine the altitude parameter.
{% endhint %}

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.flytbase.com/terrain-and-altitude-visualization/terrain-visualization/terrain-visualization-for-go-to-location-gtl.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
