Create and customize symbols

By default, the symbols or map features on your map display as red dots. You can modify the symbols to make them more visually accurate or appealing.

1. Open your map in ArcGIS.

2. Select one of the layers by clicking it.

   A drop-down list appears next to the selected layer.

3. Select Change Symbols from the drop-down list.

   The Change Symbols menu is displayed.

4. Select Change Symbols from the Options drop-down list.

   The Change Symbols window opens.

5. Choose a symbol category from the drop-down list.

   The Basic category is displayed by default. Several categories are available to choose from, including Business, General infrastructure, and Travel.

6. Adjust the size of the symbol as necessary using the Symbol size slider or by entering the pixel size in the px box.

7. Click the Apply button to preview the symbol, then click the Done button when finished.

   Click the Cancel button if you want to ignore your changes.

   You can also select one of the attributes in the map and assign a range of colors to it. The symbol will change color based on the value of the attribute obtained from the Data Archive.
