# Map and geospatial chart formatting options in Quick
<a name="geospatial-formatting"></a>

In Amazon Quick, you can choose from multiple formatting options for your maps and geospatial charts. You can view formatting options by opening the **Properties** pane from the on-visual menu located at the top right of the currently selected geospatial map. 

Quick authors and readers can also toggle the different formatting options of a geospatial map visual from the on visual menu.

# Base maps on geospatial maps in Quick
<a name="base-maps"></a>

When you create a map visual in Quick, you can change the base of the map. A *base map* is the style of map that appears beneath your data on a map. An example is a satellite view versus a street view.

In Quick, there are four options for base maps: light gray canvas, dark gray canvas, streets, and imagery. The following list contains an example of each base map option:

**Important**  
Only the light gray canvas is supported in the Asia Pacific (Mumbai) Amazon Region (ap-south-1).
+ Light gray canvas

+ Dark gray canvas

+ Streets

## Changing base maps
<a name="base-maps-change"></a>

Use the following procedure to change a base map.

**To change a base map**

1. Create a point or filled map in an analysis. For more information, see [Creating maps and geospatial charts](geospatial-charts.md).

1. On the map visual, choose the **Format visual** icon.

1. In the **Properties** pane that opens, choose the **Base map** section and then choose the base map that you want.

# Geospatial heatmaps in Amazon Quick
<a name="heat-maps"></a>

Use geospatial heatmaps to reveal patterns of marker concentration in your geospatial visuals. Heat maps display concentrations of data points using a colored overlay that highlights the intensity or concentration of the visual's markers.

**To turn a geospatial map into a heat map**

1. Open your analysis and choose the geospatial map that you want to format. When you select a visual, it displays with a highlight around it.

1. To open the formatting pane, select the **Format visual** icon from the on-visual menu.

1. On the formatting pane at left, choose **Points**.

1. Choose **Heatmap**.

1. (Optional) For **Heatmap gradient**, choose a color that you want for the **High density** and **Low density** values.

# Marker clustering on geospatial point maps in Quick
<a name="marker-clustering-on-maps"></a>

Use marker clustering to improve readability of collocated points on a map. Geospatial locations on point maps are represented using markers. Usually, there is one marker per data point. However, if there are too many markers close together, the map becomes difficult to read. To make it easier to interpret the map, you can enable marker clustering to represent groupings of locations on the map. As the reader zooms in on the map, the clustered markers leave the area marker to display separately.

**To add cluster points to a map**

1. Open your analysis, and choose the geospatial map that you want to format. When you select a visual, it displays with a highlight around it.

1. To open the formatting pane, select the **Format visual** icon from the on-visual menu.

1. On the formatting pane at left, choose **Points**.

1. Choose one of the following options:
   + **Basic** – use the default display setting for map points.
   + **Cluster points** – cluster map points together when there are many in one area.
