AISStream's live US-coast feed crowds vessel_last_known past _MAX_VESSELS
(6000) and the 'evict oldest seen_at' pass reaps the Hormuz VesselAPI rows,
which are only refreshed every VESSELAPI_INTERVAL (~4.8h). Result: the poller
was fetching 50 Hormuz vessels per 2xx but /api/vessels?bbox=Hormuz stayed
empty. Eviction now skips src=vesselapi rows (falls back to evictable-only,
clamped) so the blind-spot box stays resident between polls.
TiTiler /tiles/{z}/{x}/{y} takes a strict int for y; the @1x scale-suffix
template 422s on every SAR tile request (int_parsing on '21@1x').
sign_cog_url wrapped the Planetary Computer SAS token under a single
token= param, which Azure rejects (403→409); the token is a pre-encoded
query string and must be appended top-level (st=…&se=…&sig=…).
Proven live: correct-form URL renders a 200 image/png 256px tile.
Add GET /api/map/sentinel1?bbox=... which queries Planetary Computer STAC
(sentinel-1-grd, last 7d, most recent), signs the vv/hh COG with a SAS token,
and returns a same-origin /titiler/... XYZ tile template. Cache keyed on
quantized bbox + UTC day (20 min TTL). 429 -> 429 (Retry-After), no imagery
-> 404, other upstream errors -> 502.
Self-host TiTiler on the Pi (ghcr.io/developmentseed/titiler, arm64, 1G cap,
host loopback 8001 -> container 8000) instead of titiler.xyz. nginx
/titiler/ proxy snippet routes browser tiles to it; TITILER_PUBLIC_BASE and
TITILER_INTERNAL_URL are env-driven (no hardcoded hostnames).
Planespotters 403s server clients whose User-Agent has no contact
email; compose default UA lacked one. Leaflet popup.update() also
re-ran the bindPopup factory and wiped the thumbnail after load.
- Send a contact UA on planespotters lookups; align compose default.
- Resize the popup without re-rendering content.
- Keep hex/src on live firefighter upserts so they get a photo too.
Add planespotters.net latest-photo lookup for ADS-B aircraft.
- app/live_layers.py: fetch_planespotters_photo() (hex preferred, reg
fallback) + _normalize_planespotter_photo(); 24h TTL cache (their ToS cap).
- app/main.py: GET /api/aircraft/photo?hex=...|reg=... (422/404/502).
- app/static/index.html: .ps-photo block in ADS-B popup; lazy load on
popupopen; thumbnail links to photo page + photographer credit.
Server-side proxy, not browser fetch(): planespotters 403s any request
carrying an Origin header (every browser fetch() sends one). The thumbnail
binary is loaded by the browser straight from their CDN, never re-hosted.
Tests: 4 unit + 4 API contract (38 pass in the two files).
Stop the live HUD reconnect storm (nginx WS snippet + backoff), copy
intel/nous_client into the summarizer image, and make event ingest
idempotent on URL. GDELT uses the DOC API; NWS no longer sends bbox;
FIRMS is one ON CONFLICT batch; GET /api/aircraft serves last-known.
Health reports freshness without 503ing docker. EONET + CISA KEV added.
The Vessels layer now retunes the server-side AISStream subscription to the
client viewport instead of a static AISSTREAM_BBOX. The frontend POSTs its
quantized viewport box to /api/vessels/subscribe on moveend; the ais_stream
worker coalesces and applies it at the service's 1 subscription/s cap, then
last-known positions for the new area arrive within a couple of seconds (the
frontend does one follow-up fetch after retuning). Bounds the in-memory
vessel store across regions. Key stays server-side.
Reuse one TLS pool for overlay upstreams (8s/3s timeouts). Gzip JSON
over 1 KB. Aircraft/vessels Cache-Control max-age=5, alerts/perimeters 30.
Lifespan replaces deprecated on_event startup.
Wire the free data streams from docs/free-data-streams.md into the
dashboard as layer-panel toggles. Third-party APIs are proxied/cached
in FastAPI; raster tiles (IEM, RainViewer, GIBS) stay in the browser.
- Aircraft via ADSB.lol viewport poll (bbox required, radius ≤ 150 nm)
- Amtraker trains, NHC storms, WFIGS incidents/perimeters
- NWS + IEM SBW as /api/weather-alerts (does not collide with /api/alerts)
- AISStream worker is server-side only and idles without AISSTREAM_API_KEY
- Caltrans CWWP2 D1–D12 camera parser; FIRMS dual-write NOAA-20/21
