Get NPFMC FMP reference areas

Usage

Show/hide R code

get_fmp_areas(fmp = NULL, proj = proj_aksf())

Arguments

fmp: Character plan IDs: BSAI_GF, GOA_GF, BSAI_CRAB, SCALLOP, SALMON, or ARCTIC. NULL returns all six plans (eight features).
proj: Output CRS; NULL retains the bundled EPSG:3338 geometry.

Value

An sf object including `fmp_id`, `area_code`, `area_name`, `geometry_basis`, and `source_url`.

Details

Reference polygons are derived or republished for scientific maps; they are not legal boundary determinations. Plans overlap. Salmon has East, West, and Cook Inlet features. The crab boundary differs from the groundfish boundary south of the Aleutians. Consult DATA_SOURCES.md in the repository and [get_fmp_catalog()] before analysis.
