- **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`.
|
||||
- **FL511 Florida cameras.** Off by default; set `CCTV_FLORIDA_ENABLED=1` to load them. The camera list is the keyless FL511 traffic camera layer on ArcGIS (`services.arcgis.com/.../FL511_Traffic_Cameras`), published from a Florida Division of Emergency Management account rather than by FL511 directly, and the service carries no licence text of its own. It is paged up to 2,000 rows at a time, ordered by the layer's object id and following ArcGIS's `exceededTransferLimit`, to cover the ~4,000-camera statewide set. Frames are stills on two Divas Cloud hosts (`images-dis.divas.cloud`, `snapshots.divas.cloud`); both are host-pinned and a row whose image resolves elsewhere is dropped. `CCTV_FLORIDA_MAX_SOURCES` caps the pack (default 500, anchored per region across the state). Each catalog page is read under a 2 MiB cap and redirects are refused. Frames are fetched live at request time and never stored or redistributed. FL511's terms (fl511.com/privacy#disclaimer) license its content for individual, personal use only; any other use, including a public deployment, needs FDOT's express written consent.
|
||||
- **Catalonia (Servei Català de Trànsit) cameras.** The camera list is the keyless `https://www.gencat.cat/transit/opendata/cameres.xml` WFS/GML feed, fetched over https with redirects refused and the body read capped at 1 MiB, since the list decides ids, coordinates and which allowlisted frame path is proxied. It carries a `font` field naming the real publisher per camera; this pack keeps SCT's own highway cameras plus hotlinked Barcelona (IMI) and Terrassa municipal cameras (~130 total), each confirmed to return a real frame, so frame URLs are checked against a small host allowlist (`mct.gencat.cat`, `www.bcn.cat`, `emap.terrassa.cat`) rather than one pinned origin (a link carrying `user:pass@` userinfo or an explicit port, or pointing outside that host's frame directory, is rejected even on an allowed host; an SCT `sctidcam` must be a bare `.gif`/`.jpg` filename), and every non-SCT camera carries its real owner as a `credit` shown beside the shared `provider`. The feed carries no compass heading, so every camera loads at low heading confidence (same as TfL and Fintraffic). SCT's own feed link (`RenderService`) needed a workaround: it always 302s to a second endpoint (`TransitCamera`) on a Location the upstream hardcodes as plain http even when requested over https — refused by `fetchWithinHost`'s same-origin (scheme-included) redirect policy — and separately, `mct.gencat.cat`'s TLS setup fails the handshake with Node's fetch outright (`ERR_SSL_WRONG_SIGNATURE_TYPE`) even though other HTTP clients complete it. The loader therefore builds the `TransitCamera` URL itself, over plain http, from `RenderService`'s `sctidcam` id, rather than registering the (broken) upstream link — the only transport this one host actually serves to this runtime. Camera ids are built from the SCT camera file or the partner image path, not the feed's `fid` (which embeds an upstream server-start stamp and changes on every upstream restart), and rows the feed lists more than once collapse to one camera. The feed carries no camera status field, so a camera its publisher has taken offline still registers and shows the publisher's own "image unavailable" still (SCT and Barcelona both serve one with HTTP 200), the same as other packs without a status field. Frames are fetched at request time and never stored or redistributed. The feed itself states no licence; the pack relies on the Generalitat de Catalunya open-data portal's terms for this dataset (the licence and attribution above). Disable with `CCTV_CATALONIA_ENABLED=0`.
|
||||
- **King County road cameras.** Keyless. The camera list is one public ArcGIS FeatureServer GeoJSON query (King County DOT Road Services, "King County and WSDOT Traffic Cameras"). The `outFields` list is explicit on purpose: the layer also carries asset-administration columns — including staff names — that are never fetched. Only live, active cameras with frames on the county's own `info.kingcounty.gov` image handler are registered (the feed writes `http://`; the handler serves HTTPS, so URLs are upgraded and pinned before registration). WSDOT-owned rows in the layer are skipped because their frames are WSDOT-hosted, outside the pinned image origin; partner-city cameras hosted on the county image handler (e.g. Newcastle) name their owner as the per-camera credit. The layer publishes no facing, so headings use the shared id-hash fallback at low confidence. Uniquely, the county publishes each camera's hardware `Manufacturer`/`Model` (Cohu 3950/3965, Bosch AUTODOME, Axis PTZ domes); both are carried on the source (and served by `/api/cctv/sources`) as `model` and `manufacturer` for identified-hardware consumers (vendor-generic strings such as `PTZ` name no model and are omitted). Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_KINGCOUNTY_ENABLED=0`.
|
||||
- **WSDOT highway cameras.** Keyless. The camera list is the Esri JSON layer `data.wsdot.wa.gov/travelcenter/Cameras.json` — the same layer WSDOT's own Travel Center map consumes (~1,700 point features, EPSG:3857 geometry converted to WGS84 on load; the body carries Windows-1252 bytes and is decoded as such). Only frames on WSDOT's own `images.wsdot.wa.gov` host are registered — the catalog also lists ~70 partner cameras (Oregon DOT, City of Seattle, lodges, airports) whose own terms apply, and those are skipped rather than proxied. WSDOT's layer metadata marks the feed for "low volume" use (see WSDOT's [travel information disclaimer](https://wsdot.wa.gov/about/policies/travel-information-disclaimer)). The catalog is fetched once per CCTV catalog refresh (every 15 minutes), and a camera's frame is fetched only when that camera is viewed; frames are never stored or redistributed. The live feed's `CompassDirection` is a single cardinal (N/E/S/W), `B` (both directions — most rows), `O`, or null. A single cardinal gives a high-confidence heading (the diagonals NE/SE/SW/NW are mapped too should they appear); `B`, `O`, null, and any other code carry no single facing and use the shared id-hash fallback at low confidence. By default the 250 cameras nearest Seattle and Spokane load; `CCTV_WSDOT_MAX_SOURCES` changes the cap (8–1,200) and `CCTV_WSDOT_ENABLED=0` turns the pack off. A keyed WSDOT Traveler Information API serves the same population for higher-volume use and is deliberately not required here.

## 🎙️ Talk to It

The standalone app offers **OpenAI** and **Gemini** in the GEV MIC provider chooser. OpenAI is the initial default; your choice is saved in this browser. To use Gemini, add `GEMINI_API_KEY` in Provider Settings or your local `.env` file, then select Gemini. `GEMINI_LIVE_MODEL` defaults to `gemini-3.8-live`. The permanent key stays on the local server, which issues a constrained, single-use session credential.
|
||||
|
||||
Changing provider ends the current conversation. If voice is on, the new provider starts with the same open-mic or push-to-talk mode; a held Space key is not carried over. Gemini uses the same map actions and captions, but has no OpenAI cost meter or MINI tier. When Gemini reports that its session has expired, start voice again for a new conversation. The provider chooser does not change the OpenAI-backed AI HUD summary.
|
||||
|
||||
> Voice can use an **OpenAI API key** or, on the same machine, an opt-in signed-in **ChatGPT/Codex OAuth** session. The API-key path remains the default. Selecting ChatGPT OAuth in Provider Settings reuses an existing local sign-in or starts the Codex browser sign-in flow and selects OAuth when it completes. The OpenAI key still drives the **AI HUD summary**: a terse, five-word intelligence-style readout of the current view that regenerates as you move.
|
||||
|
||||
The OAuth option is experimental. OpenAI documents ChatGPT plan usage for the [Responses API](https://developers.openai.com/siwc/token-sharing-open-source/models-and-inference); a supported third-party Realtime contract for reusing Codex tokens has not been confirmed. A successful token mint does not establish billing or support terms.

An unrestricted key in a public deployment can be abused and billed to you. Restrict it to the **Map Tiles API and Maps JavaScript API only**: a referrer restriction applies to the Maps JavaScript API and the client SDKs, not to the web services, so a key carrying Geocoding under one is refused with `API keys with referer restrictions cannot be used with this API`.

Gemini keeps its permanent API key on the local server and mints a short-lived, single-use credential with server-owned instructions and the standalone action catalog. Its native WebSocket adapter supports open microphone and push-to-talk input, streaming audio, captions and the existing action runner. In push-to-talk, a tool call that arrives with no input, reply or tool result outstanding is answered with a failure and never runs, and neither does any other call in the reply it starts; open-microphone turns start on Gemini's server-side activity detection, which reports no boundary to check. Switching providers ends the old conversation and releases its microphone and connection; only the input mode carries over.

On Google 3D (`photoreal`) at street zoom (in below 1,400 m above ground, out

cones and the marker 2 m above the bare earth from `/api/terrain/heights`, and

the mesh hides what is behind buildings and trees. A tile is drawn draped until

its heights arrive; a geoid fallback leaves it draped. Within 900 m of the

camera, `meshSampler.js` samples the rendered surface (`scene.sampleHeight`,
|
||||
~11 m cells, nearest first, 6 ms idle budget) so lines also follow trenches,

steep streets and roads under trees. It uses the mesh floor's rules (the

viewer sits under the header with EXPAND, FIT/FILL, FOLLOW and close above the

image. FOLLOW needs the Google 3D map stack (`attachMapStackController`) and
|
||||
stops when the stack changes. Camera moves go through the application's
|
||||
navigation (`attachNavigation`), which releases aircraft and satellite tracking
|
||||
and is refused in the cockpit: turning FOLLOW on claims the camera at once, and
|
||||
FOLLOW stops when another feature takes it; a photo takes a deferred ticket
|
||||
when it starts opening and frames only if nothing newer took the camera while
|
||||
it loaded. SINCE is a stepped slider whose readout names the
|
||||
cut-off date. The panel is portable (`street-level-panel` spec, minimum
|
||||
320 × 280, `dockOnCollapse`): a floating window gives spare height to the
|

viewer, and collapsing it, double-clicking the header or SHRINK after EXPAND
|
||||
docks it. At phone width (≤720 px) the viewer height is derived from the rail

# God's Eye View — First Light
|
||||
|
||||
The intro sequence: God's Eye View coming online for the first time. A seed of
|
||||
light on Null Island grows into a culture that turns out to be drawing the
|
||||
planet. It then indexes the surface tile by tile, ingests every public feed,
|
||||
and outgrows the dish it was grown in.
|
||||
|
||||
Every number on screen comes from a real snapshot: 5,550 aircraft from OpenSky,
|
||||
15,928 satellites from CelesTrak, 246,411 fire detections from FIRMS, 10,120
|
||||
quakes from USGS, GFS wind, 1,948 subsea cable segments, AIS from Kystverket and
|
||||
Digitraffic, and 117 real public camera frames. Those cameras come from a
|
||||
catalog of 16,607 across 18 keyless agencies. The imagery is Esri World Imagery
|
||||
and NASA GIBS, fetched keyless. The score is synthesised from scratch and
|
||||
frame-locked to the same clock as the picture.
|
||||
|
||||
## Acts

|
||||
|---|---|---|
|
||||
| 0–5 s | Void | Boot console types, then implodes into a point |
|
||||
| 5–16 s | Seed / culture | Heartbeat, petri-dish ring. Mycelium grows out from 0°N 0°E; real night lights and coastlines light up as the front passes; the culture learns city names |
|
||||
| 16–30 s | Indexing | Quadtree tiles z3→z5 index in with rising resolution; the sun model is applied; 24 synthetic Esri captures ("enhance" z13→z18); full-frame Sobel feature extraction over Midtown |
|
||||
| 30–52 s | Ingestion | Aircraft, vessels, military, satellites, quakes, fires, wind and cloud, subsea cables, public cameras. Each feed has its own visual and sonic signature. Ends on the camera wall |
|
||||
| 52–60 s | Saturation | Every layer at once, data arcs, the digital-twin lattice, and the dish ring's return; containment falls, the ring shatters, OMNIPRESENT |

# Intro-sequence data snapshot: sources
|
||||
|
||||
All files are real downloads from public keyless endpoints, fetched on **2026-10-18 between 02:24 and 02:42 UTC**. Nothing here is synthesized. The scripts only filter, convert units and round. Helper scripts are in `../tools/fetch/` (`fetch_basic.sh`, `process_basic.py`, `process_tle.py`, `process_vessels.py`, `fetch_wind.py`, `fetch_bonus.py`, `cctv_fetch.py`, `cctv_select.py`).
|
||||
|
||||
JSON files are compact. Tabular layers use `{"cols":[...],"rows":[[...],...]}`, and each file's `cols` lists its columns. Coordinates are `[lon, lat]` in WGS84.
|
||||
|
||||
| File | Rows | Source URL(s) | Fetched (UTC) | Notes / licence |
|
||||
|---|---|---|---|---|
|

| `flights.json` | 5,550 airborne aircraft | https://opensky-network.org/api/states/all | 02:24:18 (`t`=1792290258) | OpenSky Network state vectors, anonymous tier. Airborne only (`on_ground=false`), non-null positions. `alt_m` is geometric altitude, or barometric when geometric is missing. Licence: OpenSky Network, non-commercial/research terms; credit "The OpenSky Network, https://opensky-network.org". |
|
||||
| `military.json` | 45 airborne aircraft | https://api.adsb.lol/v2/mil, plus https://opendata.adsb.fi/api/v2/mil (merged and de-duplicated by ICAO hex; adsb.lol wins) | 02:24 | Includes the `type` column (ICAO type code, e.g. C17, K35R). alt ft→m, gs kt→m/s. `country` is null because these feeds do not provide it. The count is low because the snapshot was taken at a quiet hour. A re-poll at 02:42 gave fewer (30 and 31 airborne). adsb.lol data is ODbL 1.0; adsb.fi open data. airplanes.live /v2/mil returned 403 and was not used. |
|
||||
| `tle.txt` | 15,928 satellites (3-line TLE) | https://celestrak.org/NORAD/elements/gp.php?GROUP=active&FORMAT=3le | 02:26 | CelesTrak "active" group. The FORMAT=tle request kept failing with connection resets after about 11 s through the proxy, while FORMAT=3le answered in 4 s. Element epochs range from day 264 to 293 of 2026. A descriptive User-Agent is required (as in server/providers/space/celestrak.js). Credit: CelesTrak / Dr T.S. Kelso. Data originates from 18th SDS / space-track.org. |

Brightness is VIIRS `bright_ti4` or MODIS `brightness`. Despite the "24h" names, the acquisitions run from 2026-10-16 00:11 to 2026-10-17 23:56 UTC. SNPP and NOAA-20 overlap, so the same fires appear twice. NASA FIRMS (LANCE); free use with credit "NASA FIRMS". |

Kystverket returns short trails, and the script uses the last vertex as the current position, checked against COG. `sog_kn`/`cog_deg` are null when AIS sends "not available". No keyless global AIS source was found.

Not produced: **military installations**. The repo's provider queries OSM Overpass by viewport only and rejects global requests. A global Overpass pull would be slow and against that design. **Datacenters**: the repo has no keyless source.

## CCTV (`../cctv/`)
|
||||
|
||||
`cctv/cam_001.jpg` … `cam_117.jpg`: 117 real frames, each fetched 2026-10-18 02:38:46–02:39:30 UTC and cover-cropped and resized to 640×360 (JPEG q88). `cctv/index.json` gives `file, name, city, country, lat, lon, source`, plus `fetched_utc`, `orig_size` and the frame `url`.
|
||||
|
||||
About 235 frames were downloaded from 20 sources, and every one was reviewed on contact sheets. Placeholders were rejected: Caltrans "Temporarily Unavailable", Vegvesen "Kamera er midlertidig ute av drift", Tallinn "NB! ÜHENDUS KAAMERAGA PUUDUB", Barcelona "Interrupció temporal de la imatge", and one all-black King County frame. Frames whose average hash repeats within the set were also dropped as placeholders, as were frames under 320 px wide or with luminance mean ≤25 or std ≤15.
|
||||
|
||||
Local time at capture: daylight in Sydney, NZ, Hong Kong and Singapore; evening or night in the Americas; pre-dawn night in Europe. The Hong Kong TD frames carry the department's own privacy-mask polygons.

"""Count distinct cameras in every keyless CCTV catalog the app supports.

Fetches each source's FULL public catalog (no anchor selection, no

DEFAULT_*_MAX_SOURCES caps) and counts distinct cameras two ways:
|

raw - distinct camera ids listed in the catalog at all
|

valid - distinct ids passing the app's own validity filters (in service /

online / official still or stream URL / plausible coordinates),

i.e. what server/providers/cctv/* would accept before capping.

The headline number written to data/extra_counts.json is the conservative
