Modify Project (Overview)
The overview provides you a project view and a rectangle where the actual map view is in relation to the project boundaries. The overview dynamically updates as the display scale changes in the main map window.
The features added to the overview map are displayed in a lower quality in the separate overview window.
To add features to the overview, click on a feature entry on the left, then click on the name of the overview (so the name is covered with an orange buffer) and click Assign.
To remove a feature class from the overview, click on the checkbox in front of the feature class name, then click Remove.
The above defined Overview looks like the following screenshot in GeoMedia Smart Client.
