Zooming in replaced the marker group with a bbox subset, so dense world
views (5k dots) thinned to a handful of pins — or zero on a wrapped world
copy, where currentBBox collapsed to a sliver and the API returned ~nothing.
Cameras only seemed to exist when zoomed out.
- vendor leaflet.markercluster 1.5.3; camera markers now render as numbered
neon-green clusters at low zoom and split into individual dots as you zoom,
so camera coverage is visible at every zoom level (spiderfy at max zoom)
- guard against null lat/lon rows (no phantom markers at 0,0)
- stale-response guard for loadCams/loadFires: rapid wheel zoom can resolve
fetches out of order and a stale bbox response blanked the map
- serve index.html with Cache-Control: no-cache so the browser never keeps
serving a pre-deploy copy after fixes land
Ingest ~4.2k direct HLS/YouTube feeds (VDOT, MDSHA, DelDOT, Iowa DOT,
OpenCCTV, etc.) from the public GeoJSON catalog. Popup plays HLS via a
CORS-safe playlist proxy + vendored hls.js, YouTube via embed, with
ffmpeg-MJPEG fallback. ALERTWest rows now use a stable camera id so
hourly scrapes do not duplicate.
- Vendored leaflet.heat 0.2.0; fires overlay is now a real heatmap
(L.heatLayer) with intensity driven by brightness or VIIRS confidence
(color mode selector) and a since= time filter (6h/24h/48h/7d/30d/all).
- Camera markers now open popups with the live snapshot thumbnail proxied
through GET /api/cameras/{id}/snapshot (backend TTL cache) + full
metadata (vendor, device, discovery source, first/last seen, coords,
source link); missing-snapshot cams show a placeholder instead of 404.
- New collapsible Layers panel (dark neon) over the map: per-layer
visibility toggles, opacity sliders (basemap/fires/cameras), live
counts legend, and a fire heat-intensity ramp that swaps for the
confidence legend in confidence mode.
- Clamp currentBBox() to world bounds so /api/cameras doesn't 422 at low
zoom (worldCopyJump spans multiple copies).
- Skip overlay reloads on moveend while a popup is open — popup autopan
no longer rebuilds the marker group and closes the popup.
- Zoom control moved to top-right so it doesn't collide with the panel.
Interactive world map panel for the dashboard:
- Vendored Leaflet 1.9.4 under app/static/vendor/leaflet/ (served via
new /static mount on the FastAPI app)
- New Map tab: GIBS WMTS raster basemap (BlueMarble_ShadedRelief_Bathymetry,
VIIRS/MODIS/Aqua CorrectedReflectance_TrueColor, VIIRS_DayNightBand),
layer picker + UTC date selector (Latest/-7d/-30d quick picks)
- /api/map/layers: curated GIBS catalog (tms, format, has_time, max_zoom)
- /api/map/times: per-layer date windows from GIBS Domains XML (6h cache,
graceful 502 on GIBS hiccup; static layers 422)
- Fire hotspots (existing /api/fires) + open cameras (/api/cameras) as
toggleable bbox-scoped overlays; dark UI matching dashboard theme
