Enum: Spatial Aggregation Preserved Quantity (SpatialAggregationPreservationEnum)

The quantity a spatial-aggregation operator holds invariant when a value is re-expressed from a source spatial support onto a target support. It keys the operator on what is preserved rather than on the mechanics of the operator.

permissible_values:
  mean_intensity:
    text: mean_intensity
    description: Preserves the area-mean intensity of the quantity (area-weighted
      interpolation). For intensive quantities that do not sum over area — e.g. modeled
      concentration, prevalence.
  total_mass_conservation:
    text: total_mass_conservation
    description: Preserves the total amount (area-proportional or population-weighted
      allocation), so the sum over the target matches the sum over the source. For
      extensive quantities — e.g. population counts.
  occurrence_intensity:
    text: occurrence_intensity
    description: Preserves occurrence density — count or line-length per unit area.
      For discrete features — e.g. facilities, roads.
  areal_coverage:
    text: areal_coverage
    description: Preserves fractional areal coverage — the proportion of the target
      cell intersected by the source feature. For coverage quantities — e.g. impaired
      waters.
