### Local receiver input (not fetched from a service)
The optional Local ADS-B layer and the broadcast-FM receiver use radio you receive yourself: a USB RTL-SDR opened in the browser through WebUSB, or the `aircraft.json` of a decoder you run on your own machine or network (`LOCAL_RECEIVER_FEEDS`). Radio samples, audio and the optional receiver location stay in the browser. Decoder feeds are read by your local GEV server and relayed only to your browser, with about a second of in-memory caching. When you select a local aircraft, its ICAO address (and an airline-style callsign) is looked up, and aircraft that qualify for a 3D model are looked up by ICAO address, through the same adsbdb proxy the public flight layers use; your server caches those answers on disk and treats them as fresh for 24 hours. Received radio data is not stored or redistributed. ADS-B is an unauthenticated public broadcast and may be incomplete, delayed, spoofed or decoded in error; it is not suitable for navigation or operational use.
### Notes on the live sources
@@ -83,6 +90,7 @@ How to read this:
- **Warendorf webcam.** The Stadt Warendorf Marktplatz webcam, registered from the curated `config/cctv_sources.warendorf.json` (the Kreis Warendorf registration-office cameras from the contributing PR are indoor waiting rooms and were left out); only the municipal image host is proxied, frames are fetched at request time and never stored or redistributed. Disable with `CCTV_WARENDORF_ENABLED=0`.
- **Live Traffic NSW cameras.** The camera list is the keyless public `data.livetraffic.com/cameras/traffic-cam.json` feed (Transport for NSW open data, CC BY 4.0); frames are stills on `webcams.transport.nsw.gov.au`, and only that host is registered. That image host answers non-browser clients with an HTML placeholder, so the proxy identifies as a browser for that one host and as itself everywhere else. Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_NSW_ENABLED=0`.
- **Open Calgary traffic cameras.** Keyless. The camera list is the public Socrata dataset `k7p9-kppz` on `data.calgary.ca`; frames are stills on the city's own `trafficcam.calgary.ca` host, and only that host is registered. Most rows publish an `http://` frame URL and the host redirects those to HTTPS, so URLs are upgraded and pinned to that origin before registration. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `quadrant` field and the quadrant suffix on each camera name are Calgary's address grid, not a bearing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. The licence requires the attribution statement above. Disable with `CCTV_CALGARY_ENABLED=0`.
- **Statens vegvesen road cameras.** Keyless. The camera list is one GeoJSON request to the OGC API Features view of the official DATEX 3.1 CCTV site table (`ogckart-sn1.atlas.vegvesen.no/ogc/features/v1/collections/datex_3_1:CctvSimple/items`), so no DATEX account is needed; frames are stills on `kamera.atlas.vegvesen.no/api/images/<cameraId>`, and only that exact path per camera is registered. Cameras the feed reports as faulty are dropped. About 135 working cameras also publish live HLS (`kamera.vegvesen.no/public/<cameraId>/manifest.m3u8`, MPEG-TS); those play as live video through the bounded in-memory HLS relay, with the still as the snapshot fallback, and only that exact manifest path per camera is registered. `CCTV_VEGVESEN_VIDEO=0` keeps every camera on stills. `orientationDescription` names the place a camera faces, not a bearing, so it goes into the label and headings use the id-hash fallback at low confidence. By default every live camera loads (~850); `CCTV_VEGVESEN_MAX_SOURCES` (8–1000) lowers the cap, keeping the cameras nearest Oslo, Bergen, Stavanger, Trondheim, Kristiansand, Bodø and Tromsø and `CCTV_VEGVESEN_ENABLED=0` turns the pack off. Frames are fetched at request time and never stored or redistributed. The NLOD attribution is registered in the Data attribution popover.
- **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.
- **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All seven registered regions are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth.
- **Radio Browser.** `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply.
@@ -90,9 +98,9 @@ How to read this:
- **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.
- **Re:Earth Terrain.** Keyless (no API key). Used two ways: (1) `src/mapStackController.js` swaps in a `Cesium.CesiumTerrainProvider` pointed at Re:Earth's `cesium-mesh/ellipsoid` quantized-mesh endpoint for globe stacks without a Cesium ion token (e.g. OSM), replacing a flat `EllipsoidTerrainProvider`; falls back to the flat provider if the endpoint can't be reached. (2) The server-side `/api/terrain/heights` proxy (disk-cached, serve-stale) resolves per-point ellipsoidal ground height for entity placement. Both are best-effort with a keyless-safe fallback (bundled EGM96 geoid math) if Re:Earth is unreachable.
- **OSRM on the FOSSGIS routing servers.** Keyless (no API key). Every route is requested by a person: clicking A and B in the Directions layer, or a voice "route from A to B". The server-side `/api/route` proxy sends an identifying `User-Agent`, pins the upstream host, accepts 2-12 coordinates, rejects any leg over 600 km or a total over 2,500 km, caps the buffered response at 8 MB, times the upstream out at 12 s, rate-limits per client, caches each route for 10 minutes, and coalesces identical requests that are in flight at the same time. Turn-by-turn maneuvers are asked for only when a caller wants them (`steps=1`), so the callers that do not read them send the smaller request. The "fix the map" link the policy asks for is in the Data attribution popover beside the OpenStreetMap credit.
- **Global Context installation context.** `/api/military-installations` queries only an allow-listed subset of OSM `military=*` and `landuse=military` features inside a maximum 10° non-dateline viewport. It caches and may serve stale mapped context, but it is neither a global installation database nor evidence of capability, activity, or absence. User-requested Google Places results remain separately sourced candidates unless their returned types explicitly establish military classification; generic offices, museums, and similarly ambiguous matches are excluded from military proximity counts.
- **Place search.** Named-place fly-to uses Google Geocoding when a Maps key is configured, then Photon's public instance, then `/api/geocode` (Nominatim search) when neither answers. `/api/geocode` shares the cockpit's Nominatim queue at no more than one request per second, sends an identifying `User-Agent` and `Referer`, caches answers for five minutes, shares one upstream call between identical searches already in flight, bounds the queue so a burst is refused rather than held, and drops a queued search whose caller has given up. It asks for one result per search and is not used for systematic or bulk queries.
- **Cockpit regional briefing.** `/api/regional-brief` rounds aircraft coordinates into 0.1° cache cells, caches results for five minutes, and serializes Nominatim calls at no more than one request per second. Google News RSS is queried with the resolved locality/region first; GDELT is used only when that RSS query fails or is empty. Google's published Google News terms restrict that source to personal, noncommercial use, so commercial deployments must disable/replace it or obtain separate permission; GDELT permits commercial dataset use with citation. The Data attribution popover identifies the active headline sources; article links retain publisher attribution. Headlines are location-query matches, not verified incidents, risk rankings, or evidence that a location is safe. Empty, partial, stale, and unavailable source states remain distinct. Open-Meteo supplies current conditions independently of the news source. `WX OFF` disables cockpit weather rendering only; the Local Info briefing still fetches its source-backed weather values and displays the required linked Open-Meteo credit.
- **Mapped installations.** OpenFreeMap military polygons use a bundled Overture/OSM name index; wide views show named points. Optional operator-configured Overpass and explicit Google Places searches keep their own source paths. Mapped data does not establish current activity or complete coverage.
- **Place search.** Named-place fly-to uses Google Geocoding when a Maps key is configured, then Photon's public instance, then `/api/geocode` (Nominatim search) when neither answers. `/api/geocode` uses the shared Nominatim forward-search queue at no more than one request per second, sends an identifying `User-Agent` and `Referer`, caches answers for five minutes, shares one upstream call between identical searches already in flight, bounds the queue so a burst is refused rather than held, and drops a queued search whose caller has given up. It asks for one result per search and is not used for systematic or bulk queries.
- **Cockpit regional briefing.** `/api/regional-brief` rounds aircraft coordinates into 0.1° cache cells, caches results for five minutes, and resolves physical regions from bundled public-domain Natural Earth polygons without reverse-geocoding requests. Google News RSS is queried with the resolved locality/region first; GDELT is used only when that RSS query fails or is empty. Google's published Google News terms restrict that source to personal, noncommercial use, so commercial deployments must disable/replace it or obtain separate permission; GDELT permits commercial dataset use with citation. The Data attribution popover identifies the active headline sources; article links retain publisher attribution. Headlines are location-query matches, not verified incidents, risk rankings, or evidence that a location is safe. Empty, partial, stale, and unavailable source states remain distinct. Open-Meteo supplies current conditions independently of the news source. `WX OFF` disables cockpit weather rendering only; the Local Info briefing still fetches its source-backed weather values and displays the required linked Open-Meteo credit.
- **Dynamic weather presentation.** While cockpit mode is active, `/api/weather-effects` requests current Open-Meteo observations for the aircraft/camera location, rounds coordinates into 0.1° cache cells, caches results for five minutes, and may retain a stale observation for up to 30 minutes during a transient outage. WMO condition code selects the visual family; observed cloud cover, precipitation, visibility, wind speed, and wind direction bound its strength and motion.

### ALPR camera mapping
The optional ALPR layer queries OpenStreetMap nodes tagged `man_made=surveillance`
and `surveillance:type=ALPR` (including case-insensitive semicolon multi-values)
through the shared Overpass proxy. Source/tag reference:
[OSM ALPR tagging](https://wiki.openstreetmap.org/wiki/Tag:surveillance:type%3DALPR).
No DeFlock software, branded assets or separate database is bundled. The layer
shows contributor-supplied locations and tags, not plate records, camera video,
current operating status, or exhaustive coverage. All manufacturers share the
ALPR category and marker color. Manufacturer, operator and camera type are shown
only when tagged, not inferred or independently verified. Every selected card
names OpenStreetMap in a smaller, muted source line beneath those details.
The optional ALPR layer reads OpenStreetMap `surveillance:type=ALPR` nodes
from a community-hosted hourly US/Canada extract, using detail vector tiles.
It shows mapped locations and available tags, not plate records, camera video,
current operating status or exhaustive coverage. OSM edit timestamps are not
presented as field-verification dates. Other regions show no ALPR data.
Queries are limited to a city-scale viewport (at most 3° per axis), at most
1,500 returned nodes, with outward-snapped query reuse and explicit stale/limited
coverage notices. A linked © OpenStreetMap credit appears for five
seconds when camera locations first display after enabling, then collapses;
Data attribution retains the full source/license entry, following the
[OSMF interactive-map guidance](https://osmfoundation.org/wiki/Licence/Attribution_Guidelines).
OSM data remains separately attributed under ODbL; querying
at runtime does not replace the license obligations. ODbL permits commercial
use and does not license the application code. If publicly using a derivative
database, follow its share-alike and access requirements; keep independent
datasets separate rather than treating the whole collection as MIT data.
Overpass hosting capacity and usage policies are separate from the data license.
Reads are viewport-bounded, with at most 16 tiles per country, four concurrent
reads per country, 1,500 displayed records and an hour-long decoded-tile cache.
Displayed OSM-derived layers retain a short inline OpenStreetMap credit, plus
OpenMapTiles while OpenFreeMap tiles are used; Data attribution retains the full credits. ODbL permits
commercial use with attribution and applicable database share-alike/access
obligations; it does not license the application code. Trimmed test-only tile
fixtures retain their provenance in `src/data/fixtures/README.md`.
### ODbL share-alike (datacenters, dams)
### Bundled OpenStreetMap data
The OSM-derived datasets are under the **Open Database License**. ODbL's share-alike applies to the **data / derived database, not this MIT-licensed code** — the two coexist (exactly how Open Infrastructure Map ships: MIT software + ODbL data). If you publicly distribute a _modified_ version of these databases, you must offer it under ODbL. Keep the "© OpenStreetMap contributors" notice (link: https://www.openstreetmap.org/copyright).
Bundled OSM-derived data is distributed under [ODbL 1.0](https://opendatacommons.org/licenses/odbl/1-0/), separately from the MIT code: [datacenters](src/data/local_data/datacenters/), [dams](src/data/local_data/dams/) (via Open Infrastructure Map), [military names](src/data/local_data/osm_military_names/), and [OSM test fixtures](src/data/fixtures/). Keep © OpenStreetMap contributors and offer modified databases under ODbL.
