Navigating the Project

...

At the top of the Contents pane, there is a series of seven buttons. By default, the leftmost button is selected: 'List by Drawing Order'.

When this button is selected, the order in which the layers are listed corresponds to the order in which the layers are visually stacked in the Map viewView. To test how the drawing order works, you will reorder the layers.

...

You will notice that, in the Map viewView, the COH_HISTORIC_DISTRICTS layer is now drawn in on top of the COH_HISTORIC_SITESLANDMARKS layer, meaning that historic sites are only visible in areas not covered by a historic district. It is possible to add transparency to the historic district layer or to symbolize it with a bold outline and a hollow fill, but, in general, it is best to have polygon layers at the bottom of the drawing order, so we will return the layers to their previous order.

...

You will now learn how to navigate the Map view View by panning, zooming, and using spatial bookmarks.

Exporting Selected Features  

To create a new layer with just our historic district of interest we need to export this selected feature.

1. In the Contents pane, right-click the COH_HISTORIC_DISTRICTS layer name and select Data > Export Features.
2. In the Geoprocessing pane, click the 'Output Feature Class' field to edit the name. Replace Replace COH_HISTORIC_DISTRICTS_CopyF with "MainStreet_MarketSquare". Ensure that you leave everything in the file path through Intro_Part1.gdb\. 

3. On the the Map tab, in the Selection group, click the Clear button to clear the selected features.

Now we will create a map of the historic district at risk of flooding due to proximity of a river. We could continue to do our mapping within the existing map, but, since we are now focusing on different thematic layers in a different geographic extent, this could be a good time to create a second map within our project.
