Working with historical markers

A historical marker is a named moment in time that you create in ArcMap. Creating historical markers makes it easier for users to connect to specific moments and also to navigate between moments for viewing and analysis. Once you have created a historical marker, the marker becomes available within the Database Connections dialog box in the Catalog window and the Change Version and Geodatabase History Viewer dialog boxes in ArcMap. When selecting a historical marker in any of these dialog boxes, you will connect to the historical version defined by the historical marker.

You can create historical markers based on important dates and times using the Historical Marker Manager command on the Geodatabase History toolbar.

To enable the Historical Marker Manager button on the Geodatabase History toolbar, select a workspace from the Source tab in the table of contents.

Historical Marker Manager works in a similar manner as Version Manager. You can view a list of all historical markers that have been created, as well as rename or remove them and edit the point in time that they refer to. To enable this command, you must have a workspace selected on the Source tab of the table of contents.
