# Map

The map plot is used to represent geographical data. 

To use the plot, drag & drop a latitude and longitude signal expressed in degrees onto the plot.

## Zoom

You can zoom and pan in the data by using the +/- icon or by dragging and scrolling in the plot.

* To zoom out to view the **entire dataset**, click on the house icon in the top right of the plot.&#x20;
* To zoom in to the **current data point**, click on the loop icon, also in the top right of the plot.

## Multiple trajectories

A trajectory is the combination of a latitude signal and a longitude signal. Multiple trajectories can be plotted on the same map plot.

Therefore, when switching to [Overlay](https://app.gitbook.com/o/3xj3gOaZBVq2qdke8xhC/s/wEBNWlmdcxXBXd7oyqyR/~/edit/~/changes/377/marple-insight/user-manuals/analysis/dataset-modes/overlay) mode, it is also possible to compare the same trajectory from different datasets.

More trajectories can be added by clicking "Add another trajectory" in the settings. Trajectories can also be deleted, renamed, and hidden from the plot.&#x20;

When multiple trajectories are defined, the zoom to view the entire dataset will zoom out until each trajectory is fully visible on the plot.

## Per trajectory settings

Per trajectory the following other settings can be applied.

#### Latitude and Longitude signal

If the longitude or latitude values do not align correctly with the map, you can apply an offset to adjust their positioning.

#### Color signal

Incorporate a third signal (e.g., speed) and define lower and upper bounds to dynamically change the color of data points based on the values of this signal. This adds an additional layer of insight to your visualization.

#### Filters

To filter out outliers, add a control signal and set an offset value to hide unwanted data points.

#### **Show Full Trajectory**

Choose whether to display all data points or only the data point corresponding to the current cursor position on the timeline.

#### **Resample Input Signals**

Similar to the scatter plot, you can resample the input signals to align their time bases for consistent analysis. See [Resampling](/docs/marple-insight/user-manuals/analysis/resampling.md) for more information.

#### **Bullet Size & Opacity**

Adjust the bullet size to your preferred dimensions, making it easier to visualize data points clearly.  Tweaking opacity allows you to make a signal more or less prominent on the plot.

## Legend

Each trajectory is shown as a seperate entry in the legend.&#x20;

<figure><img src="/files/G85dicWT36Ryz8XL0A30" alt="" width="563"><figcaption></figcaption></figure>

It is possible to drag and drop signals from the signal list into the legend to update a signal.&#x20;

When clicking on a certain row in the legend, the corresponding trajectory is highlighted.

The legend of a map plot can be put in the bottom left corner, bottom right corner, completely above the plot, completely below the plot, or it can be hidden fully.

## Other settings

#### Background

The default map is [OpenStreetMap](https://www.openstreetmap.org/#map=8/50.510/4.475). In open street maps, you can switch  between a standard map, a satellite map or a dark map. You can also change the opacity for better visibility.

You can also add  a **custom background.** To upload a custom background:

1. Click the **settings wheel** in the top right corner.
2. Enable **"Use Custom Background"**.
3. Upload your file.

#### **Overlays**

Enhance your map by adding overlays, such as **airspace boundaries**, for better context and analysis.
