Adding layers
After building the visualizations for one layer of your map, you may want to add another perspective
on your data. Power Map supports the use of multiple layers so you can stack and present geospatial
visualizations on the same map at the same time.
To add a layer, click the Add Layer button on the Power Map Ribbon. The Layer Manager task pane
opens with the configuration settings for your new layer; see Figure 6-17. At this point, you can build
the visualization needed just as you did for the first layer.
The new layer (Layer 2) enhances the map with a Heat Map visualization representing the air pressure
at each point in Hurricane Katrina's path. This new layer is presented on the same map as the first
layer, which shows wind speed and category.
You can manage the layers in your Power Map model by clicking the Layers icon (see Figure 6-18) in
the Layers Manager task pane. The Layers pane shows all of the existing layers, allowing you to hide,
delete, or edit each layer.
