Fig. 14 Activity Manager panel

This panel (Fig. 14) lists all the activity groups included in the EM graph file. Activities represent groups of stratigraphic actions that belong to the same constructive or destructive process.

Panel Layout

The panel displays a list of activities extracted from the graph’s ActivityNodeGroup nodes. Each row shows:

• The activity name with a network icon

• The associated epoch name (derived from the graph edge has_first_epoch)

When an activity is selected in the list, it can be used as a filter criterion in the Stratigraphy Manager panel.

Workflow

Populating the activity list:

The activity list is automatically populated when the GraphML file is loaded. Each ActivityNodeGroup node in the graph is extracted with its name, description, and associated epoch.

Filtering by activity:

1. Select an activity in the list

2. In the Stratigraphy Manager panel, expand the Available filters section

3. Enable the By Activity toggle

4. The stratigraphy list will show only the units belonging to the selected activity group

Activity filtering can be combined with epoch filtering. When both are active, only units matching both criteria are shown.
