How this site was made

Methodology, sources, and what we chose not to map.

This site is a public preview, built from public-record sources and not yet reviewed by the named partners. Everything below describes how it came together, what it draws on, and the consultation that still has to happen for it to speak with the right voices.

Four commitments.

  • Public-record sources only. Every layer cites NPS, NOAA, USGS, state of Hawaiʻi GIS, or peer-reviewed academic work.
  • Descriptive, not advocacy. Where the trail crosses Hawaiian Kingdom Crown Lands, we show the documented boundary and cite the documented history (Kameʻeleihiwa, Osorio). We do not litigate sovereignty.
  • Restraint, on purpose. We deliberately omit sacred-site locations NPS has chosen not to publish. More layers is not more respect.
  • This is a preview, not a final word. The cultural and historical writing is unreviewed scaffolding. We invite correction from the named reviewers and the broader Native Hawaiian community, and we will change what we get wrong.

Before this site flips to a public companion.

None of the people or organizations below have been consulted on this preview yet. Naming them is a commitment to the consultation pass we'd do before any public launch — not a claim of endorsement.

National indigenous tourism

Bruce — AIANTA

American Indian Alaska Native Tourism Association. Reviewing the cultural-restraint framing of the preview overall.

Hawaiian tourism standards

NaHHA

Native Hawaiian Hospitality Association. Reviewing voice, Hawaiian-language usage, and what's appropriate for a non-Hawaiian publisher to surface.

Hawaiian historian (TBD via NaHHA)

Academic reviewer

Reviewing the Crown Lands and 1893 / ceded-lands content in the Kealakekua chapter for accuracy and framing.

NPS

Arik — Superintendent, Ala Kahakai NHT

Operational and cultural review per NPS Pacific Islands standards. Final sign-off for any public launch.

Restraint as a feature.

The following are deliberately absent — not because we couldn't find them, but because mapping them would either compromise protection or extend beyond what public agencies have chosen to publish.

  • Sacred sites NPS has chosen not to publish — burial caves, kūpuna iwi locations, fishing kapu zones, certain heiau on private land
  • Community-sourced locations not yet published by NPS or DLNR
  • Active archaeological excavation locations
  • Endangered species nest specifics beyond what NOAA and USFWS publish

Every map layer, attributed.

How we write about Hawaiʻi.

We use Hawaiian terms throughout this site — ahupuaʻa, mauka/makai, ali'i, heiau, honu — because the English equivalents flatten meaning. Diacritics (ʻokina and kahakō) are used per the modern Hawaiian Dictionary (Pukui and Elbert) and the conventions of Hawaiian Language Online (Ulukau).

We describe Native Hawaiians (Kānaka Maoli) as indigenous to Hawaiʻi. The Kingdom of Hawaiʻi was a sovereign nation recognized by the US, UK, France, and many others before 1893; that history is documented, not contested, and we treat it accordingly.

Tell us.

aloha@alakahakai.org forwards to the team. We respond to every email. Cultural-content corrections from Kānaka Maoli readers get priority and the relevant copy gets pulled into review immediately.

For a deeper look at the trail itself, the Reading the Land companion walks through what trail surface, stones, and petroglyphs tell us.

What the conditions and 360° pages draw on.

  • Weather and alerts: NWS Honolulu gridpoint forecasts, active alerts by point and marine zone, and the Surf Zone and Coastal Waters text products, via api.weather.gov.
  • Tides: NOAA CO-OPS predictions (MLLW) at Māhukona, Kawaihae, Kailua-Kona, Nāpōʻopoʻo and Honuʻapo. Predictions, not observations; the nearest station can be miles from a chapter's shore.
  • Ocean: NDBC buoy 51004 observations; Open-Meteo's WW3-based marine model for swell just offshore of each chapter.
  • Volcanoes and earthquakes: USGS Hawaiian Volcano Observatory alert levels and daily updates (HANS API); USGS earthquake catalog, M2.5+ within 150 km.
  • Parks: NPS API alerts for the Ala Kahakai, Puʻukoholā Heiau, Kaloko-Honokōhau, Puʻuhonua o Hōnaunau and Hawaiʻi Volcanoes.
  • Storms and air: NHC/CPHC active-storm feed; Open-Meteo air quality (CAMS) for SO₂ and PM2.5 as a vog proxy. The State's monitors remain the authority.
  • 360° imagery: Google Street View and contributed photospheres, embedded from Google Maps and credited per card. They demonstrate the experience; no trail-owned capture exists yet for the corridor between the parks.
  • Photography: National Park Service photographs (public domain, credited "NPS") and Wikimedia Commons images listed in the attribution file.

Every feed is fetched by a server script every ten minutes into one JSON file; when a source fails, the last good reading is kept and the page timestamp says so. Nothing here should be used in place of official warnings.
