The CCTV layer kept every loaded camera live: each view change touched every
icon, every notification rebuilt every camera's state, and the picker listed
the whole catalog. With the default 4,000 cameras, a continental drag ran at
152-179 fps with 18-24 frames over 30 ms (worst 112 ms). It now runs at
235 fps with none. The layer now:
- shows icons only on or near the screen, and when zoomed out keeps one camera
per world-anchored cell (healthy feeds first), so panning keeps the same
cameras;
- grounds and draws coverage only for the cameras in view, the active camera
and its coverage neighbours, retrying a camera at most twice per view regime;
- reruns the view pass while the camera moves, paced by its own cost, and
projects with one matrix per pass instead of a Cesium call per camera;
- keeps the billboard buffer-usage hint fixed, so showing or hiding a few
icons no longer rewrites the vertex data of every billboard;
- lists the cameras in view (active camera first) in the picker, closing with
the count of cameras outside the view, and builds the full camera list in
the UI state only when it is read.
Wind (NOAA GFS and ECMWF IFS: animated particles, colour field, a reading at map centre), observed weather (NOAA MRMS radar, GOES and NESDIS infrared clouds, lightning density) on one shared history timeline, NHC and CPHC cyclone advisories with tracks and cones, and a WEATHER panel in the right rail. On 3D Tiles the observed products render as raised shells with a sharper window around the view.

Every pack sets headingConfidence on each camera, but nothing consumed it:
a bearing synthesized by fallbackHeadingFromId (a hash of the id string,
no geographic input) rendered exactly like a surveyed one — 2,827 of 3,997
cameras in a default catalog. Fixes#639.
Two consumers, plus a passthrough:
- HUD: the heading token is tagged when the bearing is synthetic —
`HDG 194° (ESTIMATED)` — so a hash never reads as a measured facing.
- Wireframe: a low-confidence camera draws its coverage frustum with dashed
polylines instead of solid ones. Colors, widths, and the active/idle
emphasis are unchanged; the dash is the only signal.
- Public camera state gains `headingConfidence` (the raw pack flag) and
`headingEstimated` (the derived bit) so UI consumers never re-derive it.
A human-vouched pose always wins over the pack flag: a manually saved
calibration (calSource:'manual') or a curated catalog entry
(poseSource:'curated') is never presented as estimated, mirroring the CAL
badge states in calibration.js.
- src/layers/cctv/headingConfidence.js: pure helpers (isHeadingEstimated,
headingHudToken)
- src/layers/cctv/headingConfidence.test.mjs: confidence normalization,
calibration/curation overrides, HUD token formatting
- src/layers/cctv/presentation.js: HUD token + public-state passthrough
- src/layers/cctv/rendering.js: dashed materials for estimated bearings
