Adjusting the map scale for the PAAT session

You can choose the scale to use with the Positional Accuracy Assessment tool (PAAT) session by adjusting the scale of the map. The PAAT keeps the scale at the zoom level you selected until you change the zoom level.

Setting a scale this way overrides the scale defined by the grid cell and allows you to use a consistent zooming level for all features in the evaluation and reference layers.

步骤：

1. Start ArcMap.
2. If necessary, load data in the map.
3. On the main menu, click Customize > Toolbars > Data Reviewer.
4. On the Data Reviewer toolbar, click Data Reviewer > Positional Accuracy Assessment.

   The Positional Accuracy Assessment toolbar appears.

5. Start a PAAT session.
6. Use the zooming tools on the Tools toolbar to change the map scale.
