## Using Split Map modes

Interact with two synchronized maps displayed side-by-side (Dual Maps) or overlaid (Swipe Maps).

The two maps in Split Modes can show different data layers, letting you make quick visual comparisons between different data sets.

To change the split mode, click the **Split Mode** button.

### Split Map Modes

After clicking the button, select one of three options:

- [Single Map Mode](https://docs.foursquare.com/analytics-products/docs/maps-split-modes#single-map-mode)
- [Dual Maps Mode](https://docs.foursquare.com/analytics-products/docs/maps-split-modes#dual-maps-mode)
- [Swipe Maps Mode](https://docs.foursquare.com/analytics-products/docs/maps-split-modes#swipe-maps-mode)

# Single Map Mode  
Use Single Map mode to display a single view of your map. This is the default view mode.

# Dual Maps Mode  
Use **Dual Maps** mode to display a synchronized side-by-side comparison of the same map area with your choice of layers.

Click **Unlock Viewport** to decouple the map's shared viewport, allowing you to compare two areas of the map side-by-side.

Toggle **Synchronize Zooms** to unlock zoom levels for each map in dual map mode.

# Swipe Maps Mode  
Use **Swipe Map** mode to compare different data layers by dragging a sliding separator to reveal more of either of the two overlaid maps.

Since the maps are overlaid rather than side-by-side, it is often easier to detect subtle differences in the swipe mode.

### Selecting Layers in Split Maps  
To select which layers display in the split maps, open the **Legend**.

Click **Hide Layer** on layers you want to hide, and **Show Layer** on layers you want to show.

The left visibility icons toggle visibility on the left map, while the right visibility icons toggle visibility on the right map.

You can also drag and drop layers from the **Layer** tab directly onto split maps.
