Hawaii Habitat Provider

AI1SAD includes a static/offline Hawaii habitat adapter for bounded structural context. It does not ingest live habitat feeds at runtime.

Provider module: app/providers/hawaii_habitat.py

Purpose

Represent baseline nearshore structure context for surveillance planning:

  • reef-channel
  • shallow reef
  • reef edge
  • hardbottom
  • submerged vegetation
  • sandy bottom
  • dropoff
  • nearshore structure
  • habitat visibility context

These are historic/static baseline layers, not real-time observations.

Source Direction (Baseline Candidates)

  1. NOAA NCCOS Oahu shallow-water benthic habitat maps
  2. Hawaii Statewide GIS benthic-habitat layer
  3. Pacific Islands Benthic Habitat Mapping Center Oahu resources

Source dates are retained in metadata and must not be represented as current conditions.

Signal Types

  • reef_channel_habitat
  • shallow_reef_habitat
  • reef_edge_habitat
  • hardbottom_habitat
  • submerged_vegetation_habitat
  • sandy_bottom_habitat
  • dropoff_habitat
  • nearshore_structure_context
  • habitat_visibility_context

Profile Fields

Each static profile includes:

  • id
  • region
  • island
  • location_name
  • coordinates and polygon reference
  • habitat_type
  • geomorphology_type
  • biological_cover_type
  • depth_band_m
  • edge_context
  • channel_context
  • visibility_context
  • confidence
  • source_name
  • source_url_reference and/or source_notes
  • source_date
  • data_freshness
  • baseline_only: true
  • pack_id
  • visibility

Bounded Behavior

  • Habitat alone must not create high warning.
  • Reef-channel and edge context can modestly raise surveillance attention.
  • Stronger attention requires stacked activity/sighting/biological/weather/SST/exposure context.
  • Historic baselines influence interpretation only and should reduce confidence when stale.

Privacy and Output Safety

  • Public outputs exclude private_notes and restricted fields.
  • Baseline metadata is public-safe and source-attributed.

Operational Caveat

Historic GIS baselines are structural reference layers only. They are not live water-state, animal-presence, or current-condition observations.
