DEM and orthophoto GeoTIFFs

The map DEM is a hillshade visualization. These links provide the source elevation raster and orthophoto for local analysis. The DEM uses the island-specific datum.

Time normalization

Cook Islands local time

Raw GPS, recorder files, darktable metadata, and EXIF-derived timestamps are the source of truth. Derived links should remain reviewable when camera offsets or audio timestamps are ambiguous.

Raw audio files: 553
Linked audio notes: 457
Unmatched audio: 0

Darktable truth

Photo catalog source

Darktable available: False. Records: 0. Public URLs come from the field_guide Backblaze manifest; capture time, camera, and HS site tags are checked against the local darktable catalog where possible.

Skipped by CI26_SKIP_DARKTABLE_TRUTH=1.
