Strat Units

Unit Attributes

  • Site Code
  • Unit ID
  • Label
  • Class [Context, Subgroup, Group, Landuse]
  • Type [Deposit, Fill, Cut, Masonry, Skeleton, Timber]
  • Status [Allocated, Assigned, Void]
  • Aggregate Unit
  • Phase
  • Period

Strat Relations

  • Above / Below (directed graph)
  • Same-As (undirected graph)
  • Contemporary With (undirected graph)

Rules / Heuristics

Any Relations:

  • Cannot be between same Unit
  • Both Units must be same Class

Same-As Relations:

  • Both Units must be Context class
  • Adding relation should not create cycles (no intersection between successors and predecessors)
  • Both Units must have the same Aggregate Unit if set
  • Both Units must have the same Period / Phase if set


Processing

Load

Validate

  • Validate Units
  • Validate Above/Below relations
  • Validate Same-as Units

Resolve

  • For each Same-As relationship add all Above/Below relations to each Unit

Validate

Reduce

  • Remove all redundant Above/Below relations (transitive reduction)

Aggregate

  • Validate all Context Units have an Aggregate Unit
  • For each Context Above/Below relation where the Aggregate Unit is different between the Above and Below Units, add an Above/Below relation between the Aggregate Units to the Subgroup matrix
  • Reduce the Subgroup matrix
  • Validate all Subgroup Units have an Aggregate Unit
  • For each Subgroup Above/Below relation where the Aggregate Unit is different between the Above and Below Units, add an Above/Below relation between the Aggregate Units to the Group matrix
  • Reduce the Group matrix
