#build_geo_json_feature_deduped(seen, shape_key) ⇒ Object (private)

Yields once with skip_geometry true or false depending on whether shape_key [shape_type, shape_id] has already been recorded in seen.

First occurrence of a shape: yields skip_geometry=false (full geometry fetched). The shape is recorded in seen only if the block returns a non-nil feature, so shapes that produce no feature (e.g. no geographic item) are never marked seen. Subsequent occurrences: yields skip_geometry=true (geometry skipped, nil in feature).

When seen or shape_key is nil (deduplication disabled or no shape available), yields skip_geometry=false unconditionally.

#otu_distribution_is_absent(otu, descendants: false) ⇒ Hash

Returns GeoJSON FeatureCollection of absent FieldOccurrences and AssertedDistributions for the OTU, its coordinate OTUs, and ancestor taxon names (traversed via TaxonNameHierarchies).

Parameters:

  • descendants (Boolean) (defaults to: false) —

    when true, also include direct absents from descendant OTUs. Off by default: a descendant's absence does not propagate up to the OTU, and a sibling descendant's presence in the same region may contradict it. Use only when the caller wants a clade-wide visualization.

Returns:

  • (Hash) —

    GeoJSON FeatureCollection of absent FieldOccurrences and AssertedDistributions for the OTU, its coordinate OTUs, and ancestor taxon names (traversed via TaxonNameHierarchies).
