The MIT license applies to AKsf code. It does not replace source-data terms.

  • ADF&G: Alaska Department of Fish and Game, Division of Commercial Fisheries. Credit ADF&G on any map or analysis using its data. The agency provides data without express or implied warranty and recommends reading associated metadata. Preserve attribution when redistributing derivatives. The source service metadata is recorded by the rebuild script; source URLs are in the bundled manifest.
  • NOAA Fisheries: U.S. government spatial products, provided as-is. Retain NOAA attribution and source-vintage information. ATB is a broad-scale managed-area inventory, not a certification of current fishing regulations.
  • Natural Earth: public-domain cartographic data. Credit Natural Earth to help distinguish its generalized land from authoritative fisheries boundaries.
  • NPFMC: plan documents are cited as the source of management definitions. AKsf does not redistribute Council PDFs or claim ownership of them.

Suggested map attribution: “AKsf reference geometry; NOAA Fisheries and Alaska Department of Fish and Game spatial data; Natural Earth land. See AKsf source manifest for retrieval dates and derivation methods.”

NOAA closure vignette example

inst/extdata/closure-example contains two records from NOAA AKRO’s Habitat_Restrictions layer: GOA_Slope_HCA.htm and GOA_Coral_HPA.htm. Retrieved 2026-09-21; both retain the source annotation steve.lewis, akro, 01/19/15. This is a historical teaching snapshot, not a current closure inventory. Original attributes and service geometry requested in WGS84 are preserved. The adjacent manifest records IDs, query URL, retrieval time, and SHA-256; layer metadata is included. NOAA/AKRO is the source; this U.S. federal government data is not relicensed as AKsf code. Retain attribution and consult NOAA regulations and notices for current restrictions.
