8 Symbology: Change how the map looks

We will change the visual of the USA_48 layers using Symbology. You might notice an arbitrary, peculiar-looking polygon in the middle of the USA_48. It helps to compare how map projects present the conterminous US differently when we change the layer’s spatial reference.

1. Right-click the USA_48 layer, choose Symbology
2. In Primary symbology, choose Unique Values
3. In Field 1, choose STATE_ABBR
4. Now, we will differentiate the “peculiar-looking” polygon in the state layer. Click “…” in the Classes tab and choose “Remove heading and classes.”: (Figure)
5. Click the “+” icon: (Figure)
6. Scroll down to the bottom in the Select values to add pane, choose “ZZ,” and click OK.
7. Now your map looks like the figure below: (Figure)
