Bake the EOV membership and precomputed-indicator layers into a store

Source: R/eov.R
obis_eov_bake.Rd

Adds two tables to an obis_h3 DuckDB store:

  • eov — (eov, taxonID) membership, each EOV's seeds expanded to their full descendant set over the baked WoRMS taxon table.

  • idx_h3_eov — precomputed indicators per (eov, res) for res 1-7, so an EOV tile map reads a small clustered lookup instead of re-aggregating occ_h3 on every tile.

Usage

obis_eov_bake(con, eov = NULL, esn = 50L, verbose = TRUE)

Arguments

con

a DBI connection to a writable store with occ_h3 + taxon, with the duckdb h3 extension loaded.

eov

EOV name(s) to bake; default all.

esn

expected sample size for ES(n); default 50.

verbose

message progress.

Value

invisibly, a data frame of eov and its member-taxon count.

Details

Requires taxon (see data-raw/migrate_add_taxon.R) and, for complete coverage, a closed taxon tree (see obis_taxon_fill_gaps()) — any EOV member whose AphiaID is missing from taxon is silently excluded.
