> 2026-06-08. Both Phase-1 tracks from [watchduty-scrape-approach.md](watchduty-scrape-approach.md) run. > Incident root: `https://simtable.acequia.io/incidents/2026-CA-Sorrento/`. Fire at (32.9101, −117.2136).
## Track A — fire-lookout cameras by roster proximity ### Roster-namespace fix (important) `getCameraDataByLoc` returns `data.{locs,cams}`, two layers: - **`locs.data`** = location/clustering points `{id, lat, lon, st, lp}` — `id` here is a **location id**, NOT a camId. (My first pass used this and got garbage: "roster id 7695" mapped to a Riverside Caltrans cam in the timelapse namespace — different id space.) - **`cams.data`** = the real cameras (13623 records), cryptic keys: `id` (= timelapse camId), `cn` (camName), `lid` (→ `locs.id` for geography), `p/t/z` (pan/tilt/zoom), `fov`, `off`, `img`, `hn` (host). **Correct geography join:** `cam.lid → locs[lid].(lat,lon)`. Verified: cam **13500** `cn=UCSD_TDLLN_1`, lid=9992 → (32.8727, −117.2421), 4.9 km from the fire. ✅ ### Selection 66 cameras within 15 km. Most are **Caltrans freeway cams** (`C###_…`, fov 45°, traffic) — **deliberately skipped** (low value for fire, ~50 of them; not silently — listed here as omitted). The dedicated **fire-lookout cameras** within ~10 km, all grabbed for 0900–1500 PT (16:00–22:00 UTC) 2026-06-08: | camId | name | dist | frames | |---|---|---|---| | 13500 | UCSD_TDLLN_1 (PTZ) | 4.9 km | 68 (grabbed earlier) | | 13501 | UCSD_TDLLN_2 (PTZ) | 4.9 km | 57 | | 9424 | SDSC_Fixed_East | 3.8 km | 57 | | 11268 | SDSC_Fixed_East_Mono | 3.8 km | 57 | | 9418 | Mt_Soledad_Fixed_North | 8.5 km | 57 | | 11221 | Mt_Soledad_Fixed_North_Mono | 8.5 km | 57 | **Total: 353 JPEGs across 6 cameras, 0 failures, local == remote.** Layout per the documented `…/ops-alertcalifornia/<camId>/YYYY/MM/DD/` + telemetry sidecar. Grabber: [grab-alertwest.py](../skills/grab-alertwest.py) (looped per camId). > Skipped (available if wanted): the ~50 Caltrans freeway cams within 15 km, and fire cams in the 10–15 km > band (Mt Soledad is the farthest kept). `_Mono` = monochrome/low-light variant of the same mount.
## Track B — WatchDuty perimeter + evac zones (public maptiles) Unlike the 406-gated `api.watchduty.org`, **`maptiles.watchduty.org` is public** (no auth, no gating from plain curl). TileJSON gives the templates: - `…/fireperimeters_active/{z}/{x}/{y}` (MVT, maxzoom 14) - `…/evaczones,evaczone_labels/{z}/{x}/{y}?app_version=2026.6.2-b` (MVT, maxzoom 16) Fetched a 3×3 z=14 grid around the fire (tile 14/2857/6604). **Decoded MVT → GeoJSON** (mapbox-vector-tile, georeferenced via tile bounds; verified coords land on the fire): - **`perimeter-101783.geojson`** — 1 Polygon, 222 pts, bbox lon −117.217..−117.207 / lat 32.907..32.913 (~1×0.65 km, consistent with 90 ac). **source = FIRIS**, `source_date 2026-06-08 18:25:06 UTC`. This is the authoritative active-fire outline. (Only the center tile had perimeter data; 8 neighbors empty 204.) - **`evaczones-101783.geojson`** — 82 zone polygons across the 9 tiles (Sorrento zones SDC-1444-B/C, SDC-1492-C per CE's recon; labels live in the separate `evaczone_labels` sublayer, not captured here). Raw `.pbf` tiles kept under `watch-duty/tiles/` as provenance. All PUT to `…/2026-CA-Sorrento/watch-duty/` (201).
## Net Sorrento dataset now ``` incidents/2026-CA-Sorrento/ ├── ops-alertcalifornia/{13500,13501,9424,11268,9418,11221}/2026/06/08/ (353 frames + telemetry) └── watch-duty/ ├── geo-event-101783.json, cameras-realtime.json, capture-summary.json (CE) ├── perimeter-101783.geojson (FIRIS outline) ├── evaczones-101783.geojson (82 zones) └── tiles/… (raw MVT provenance) ```
## Still open - Reports/updates feed (WatchDuty API path unknown; UI-only) — needs CE network-watch on the updates panel. - Aircraft tracks (MEMBERS-tier) — needs CE with a member session. - Evac-zone **labels** (separate MVT sublayer) — decode `evaczone_labels` if names are wanted on the polygons. - WatchDuty user-submitted imagery — none seen in CE's recon; revisit if the incident grows.
