Coverages created or updated in CSAR format include a bounding polygon that encompasses the entire extents of a coverage. If the polygon created automatically for the selected coverage is not acceptable, a new polygon can be created manually or automatically. When redigitizing an entire polygon, the existing polygon will need to be removed manually.
By default, the polygon is digitized using the Point-to-Point method. You are not limited to this method, however, there are several digitizing methods available. The method can be changed at any time without damaging the polygon. For more information on the digitizing methods, see Digitize.
The Grab tool is a useful digitizing tool when creating polygons. It allows you to select a pre-existing polygon feature on another layer and it then creates a copy of the feature on the Bounding Polygon layer. See Grab for more information.

Procedure
1. Open a raster surface or point cloud.
2. Select the Bounding Polygon layer for the surface.
3. Select the Digitize New Boundary Polygon command.
Digitizing mode is enabled. Note the change in the cursor’s appearance.
4. [Optional] Right-click and select Edit Line to choose an alternate digitizing method.
5. Click the Display window to add vertices until the polygon has the appropriate shape and size.
If necessary, the <Backspace> key can be used to remove the last vertex added. |

6. Use on of the following methods to turn off Digitizing mode and complete the bounding polygon:
• Select the Digitize New Boundary Polygon command again.
• Right-click in the Display window and, from the pop-up menu, select Edit Line > Close Area.
• Press the <End> key.
The newly digitized boundary is added to the display.
