Product Overview - Temporal Relations

Each stratigraphic relation above/below implies a temporal relation as well: As unit 7 is above 8 then 7 is later than 8. If two units have no stratigraphic relation we have no information of their temporal relation based on topological observations during the excavation. Between units that have no stratigraphic relation as 6 and 3 or 12 and 13 you might have additional non topological arguments to set additional temporal relations. This can be done by drawing special edges. You can either set a source unit to be later than a target unit or set both units as contemporary.
