Submarine cable areas

The general footprint of commercial and research submarine cables in U.S. waters as 2,816 areas (polygons; the first-15 list calls them lines). A cable area may hold one or more cables; most records carry no cable name (shortname, cablesystem, owner mostly empty), so names fall back to a generic label plus the source OBJECTID, which is the id. The native status (In Service, ...) is empty for 2,411 records, so status is 'charted'.

• Collection: noaa_submarine_cables v1.0.0, 2816 features, GeoParquet 1.1 (places.parquet) and PMTiles (places.pmtiles, layer noaa_submarine_cables)
• Licence: CC-PDDC - U.S. federal government work (NOAA); the AGOL item carries NOAA's 17 U.S.C. 403 notice (material 'not subject to copyright protection within the United States'; foreign copyrights may apply).

• Refresh: monthly, by .github/workflows/sync.yml (re-fetched only when the source's editingInfo.dataLastEditDate or record count changed)

Sources and provenance

Machine-readable copy: provenance.json (also in collection.json and the Parquet footer).

Schema

Native attributes keep the source layer's names; a native name equal to a gazetteer column ignoring case (NAME vs name) is suffixed _src.
