In this segment you will see how to open the base map for the tutorial and save a new copy of it in which to create a time animation. To do so, click File and click Open, then navigate to your Animation in ArcMap folder and double-click Population_Change_Start.mxd.

The map contains background layers, and two layers containing population information: State Population and County Population. These two layers contain population figures recorded from the year 1800 to 2000, in 10–year increments.

Click File and click Save As. Navigate to your Animation in ArcMap folder and type Population_Change.mxd for the name of the map document. Click Save.
