Add a heat map

When a layer contains a large number of point features, showing each feature individually on the map is often not useful. In this scenario, point features often overlap, making it difficult to distinguish between features. Even when they do not overlap, it is usually difficult or impossible to visually extract meaningful information when hundreds or thousands of points are shown all at once.

One approach to resolving this issue is to generate a heat map. A heat map represents the geographic density of point features on a map by using colored areas to represent those points. The areas will be largest where the most points are concentrated together.

  1. Click the Heatmap button in the map ribbon.
  2. Choose the point layer you want to use to create a heat map.
  3. Use the switch to turn the heat map on.
  4. Choose the color scheme and area of influence to be used for the heat map.

The heat map layer is added to the map and the Contents pane. You can turn the heat map on and off, rename, and remove as you would other layers. You can also set the visible range of the heat map, if desired.
