 - **Via Lietuva / Eismoinfo (Lithuania).** Public road-camera catalogs and periodically updated still images from [Eismoinfo](https://eismoinfo.lt/), credited to Via Lietuva / eismoinfo.lt in the app. **Off by default.** The camera endpoints are the eismoinfo.lt website backend and are not among the services listed in Via Lietuva's [open-data statement](https://eismoinfo.lt/eismoinfo-backend/content?id=44), whose conditions are attribution and reuse on the same terms. Until the statement is confirmed to cover the camera photos, the pack loads only when an operator sets `CCTV_LITHUANIA_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to Eismoinfo. `eismoinfo-backend/camera-info-table` is joined by ID to `layer-static-features/VKR`. Without `lks=true`, the latter returns WGS84 `[latitude, longitude]`; the table's `x/y` instead use LKS-94 metres. Only the official HTTPS `/eismoinfo-backend/image-provider/camera/last?id=…` image endpoint is registered. Catalogs use the shared 15-minute cache; frames are fetched on demand and never bundled or archived. These are periodic snapshots, not continuous video. Camera headings are low-confidence estimates. No API key is required. `CCTV_LITHUANIA_MAX_SOURCES` defaults to 400.
 - **Freeway Bureau and Highway Bureau, MOTC (Taiwan).** National freeway cameras use the Freeway Bureau’s keyless [MOTC 2.0 CCTV table](https://tisvcloud.freeway.gov.tw/history/motc20/CCTV.xml), refreshed daily and fetched at runtime (never bundled). Freeway Bureau data follows the [Open Government Data License, Taiwan v1.0](https://data.gov.tw/license); the app credits the Bureau, names the dataset and links the licence. If that catalog is unreachable and no last-good source list exists, the app falls back to the Highway Bureau’s free [provincial-road CCTV XML feed](https://thbapp.thb.gov.tw/opendata/), with attribution as requested by the Bureau. Its MJPEG streams are accepted only from cctv-ss01 through cctv-ss08.thb.gov.tw over HTTPS; the frame proxy extracts one bounded JPEG per request. This fallback covers provincial roads, not national freeways. Neither feed requires an API key. CCTV_TAIWAN_ENABLED=0 disables both; CCTV_TAIWAN_MAX_SOURCES defaults to 600 (bounded to 1–2000).
+- **Québec CCTV (MTQ / Québec 511, Montréal and scenic links).** `public/quebec-cameras.json` contains 680 MTQ positions from the official georeferenced WFS (CC BY 4.0), 426 Montréal camera locations derived from OSM (ODbL 1.0), and 14 scenic records with per-row provenance and accuracy. The 680 MTQ cameras play the operator's five-second MP4 clip directly in the browser from `www.quebec511.info/Carte/Fenetres/camera.ashx?id=<id>&format=mp4`; Québec 511 refreshes those clips every few minutes. A second browser request supplies an approximate map still. The app does not proxy, store, or read video pixels, and no camera images are bundled. Montréal and scenic entries have provider-page links rather than direct frame URLs; their source-page terms apply. The video remains hosted by Québec 511 under its service terms. No API key is required; `CCTV_QUEBEC_ENABLED=0` disables the pack.
 
 - **Google Maps Platform.** You supply your own API key and are bound by [Google's ToS](https://cloud.google.com/maps-platform/terms). Google Maps Content (tiles, geocodes, places) **may not be cached, stored, rehosted, or committed** — this app only ever uses it live, which is the compliant pattern. The "Google" attribution is displayed on the globe and must stay visible. Restrict your key (see [SECURITY.md](SECURITY.md)).
 - **OpenSky Network.** Its license is **non-commercial**, and operational use of the REST API in a live product can require a prior written agreement with OpenSky — even for non-profit/government use. If you deploy this commercially, contact OpenSky for your own terms. The flights layer is a toggle and runs anonymously by default.

 - **DelDOT live video cameras.** The keyless `tmc.deldot.gov/json/videocamera.json` catalog supplies active cameras and official `https://video.deldot.gov/live/…/playlist.m3u8` links. The local server transiently buffers bounded MPEG-TS segments in memory and deletes them on session release or idle expiry. No recordings are retained. `CCTV_DELDOT_ENABLED=0` disables the pack. Public availability is not a blanket redistribution license; deployment beyond personal local viewing needs confirmation of applicable DelDOT terms.
 - **Fintraffic weathercams.** The camera list is one keyless GeoJSON request to `tie.digitraffic.fi/api/weathercam/v1/stations` (809 stations / 2,275 presets), sent with the `Digitraffic-User: gods-eye-view` header the service asks clients to identify themselves with and with gzip; frames are stills on `weathercam.digitraffic.fi`, refreshed on each station's 600 s collection interval, which is also the client's ambient-still refresh cadence for this pack (the active camera keeps the usual 10-second refresh). One preset (a fixed camera view) is one camera; stations not `GATHERING` and presets not `inCollection` are dropped. Attribution is required by the CC BY 4.0 licence and is registered in the Data attribution popover. `CCTV_FINTRAFFIC_ENABLED=0` is the kill switch.
 - **DriveBC highway cameras.** The camera list comes from the keyless `https://www.drivebc.ca/api/webcams/` endpoint served by the DriveBC.ca site ([bcgov/DriveBC.ca](https://github.com/bcgov/DriveBC.ca)); frames come from `https://www.drivebc.ca/images/<id>.jpg`, built from the numeric camera id. DataBC's [DriveBC HighwayCams](https://catalogue.data.gov.bc.ca/dataset/bc-highwaycams) catalogue entry publishes the same cameras under the Open Government Licence – British Columbia, but its CSV still lists the retired `images.drivebc.ca` frame URLs, which now return a placeholder. The licence's attribution statement is required and is registered in the Data attribution popover. By default the 250 cameras nearest Vancouver and Victoria load; `CCTV_DRIVEBC_MAX_SOURCES` changes the cap and `CCTV_DRIVEBC_ENABLED=0` turns the pack off. Some cameras in the feed are supplied by partners (TransLink, the City of Vancouver, the City of Surrey, Parks Canada / Alberta Motor Association and others); the feed's per-camera credit is carried onto the camera record and shown beside the provider in the CCTV panel.
+- **City of Ottawa traffic cameras.** The keyless `traffic.ottawa.ca/map/camera_list` JSON supplies an id, coordinates, an English/French description and a type; frames are city-served JPEG stills built from the id at `traffic.ottawa.ca/map/camera?id=<id>`, and only that directory is pinned. MTO cameras carried on the city feed keep their owner as a per-camera credit. The feed publishes no bearing, so headings use the shared id-hash fallback at low confidence, and no status field, so a camera the city takes offline still registers. Frames are fetched at request time and never stored. The city publishes no explicit reuse licence for this feed; deployment beyond personal local viewing needs confirmation of applicable terms. `CCTV_OTTAWA_MAX_SOURCES` caps the pack (default 250, nearest downtown) and `CCTV_OTTAWA_ENABLED=0` turns it off.
+- **World cams image subset.** The normal CCTV catalog adds 166 Icelandic Road and Coastal Administration cameras, 1,176 Oregon TripCheck stills, and 1,054 MLIT river cameras from the curated `config/cctv_sources.world-image-cameras.json` export; disable it with `CCTV_WORLD_CAMERAS_ENABLED=0`. The server validates and pins each image URL to its provider path. [Vegagerðin's data-service licence](https://www.vegagerdin.is/vegagerdin/gagnasafn/vefthjonustur/terms-and-conditions) permits reuse with attribution but excludes third-party rights; [ODOT allows TripCheck image use and requests credit](https://www.tripcheck.com/Pages/Frequently-Asked-Questions); MLIT's [site terms](https://www.river.go.jp/kawabou/kwb_apend/html/caution.html) are CC BY-compatible with attribution and warn against high-volume/periodic collection, so those frames refresh at ten minutes per camera. Images are not bundled or persisted; a bounded 32 MB in-memory cache reuses them until the per-source cadence. The 249 NZTA Journey Planner rows are excluded because its [website terms prohibit scraping](https://www.journeys.nzta.govt.nz/about-this-site/terms-of-use); use an authorized API feed or obtain permission before adding those rows.
 - **TxDOT ITS cameras.** The catalog comes from the keyless `its.txdot.gov/its/DistrictIts/GetCctvStatusListByDistrict` endpoint, one call per district. Frames come from the per-camera `GetCctvSnapshotByIcdId` endpoint, which answers JSON carrying a base64 JPEG rather than an image body; the proxy decodes it only for responses from the official TxDOT origin and validates the JPEG header before serving. Only cameras reporting `Device Online` are registered. Districts default to Austin and San Antonio (`CCTV_TXDOT_DISTRICTS`; 25 codes exist statewide); `CCTV_TXDOT_MAX_SOURCES` caps the pack and `CCTV_TXDOT_ENABLED=0` turns it off. Frames are fetched live at request time and are never stored or redistributed.
 - **Tallinn ristmikud.** Intersection camera stills are fetched live from `ristmikud.tallinn.ee` (`/last/camNNN.jpg`). The curated catalog (`config/cctv_sources.tallinn.json`) supplies coordinates and heading priors; only server-registered ristmikud HTTPS URLs are proxied. Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_TALLINN_ENABLED=0`.
 - **Tarktee / Transpordiamet.** Estonia road-weather camera locations and current JPEG URLs come from keyless DATEX2 endpoints on `tarktee.transpordiamet.ee` (`/api/v1/datex/roadCameraLocations` + `roadCameraImages`). Frame URLs rotate with each capture; the 15-minute CCTV source cache refreshes them. Only `https://tarktee.transpordiamet.ee/images/…` URLs are registered. Disable with `CCTV_TARKTEE_ENABLED=0`.
