# 01 — What alert.live is + the source videos (the semantic model)

Per the [video-to-brochure method](https://redfish.acequia.io/guerin/.agents/7b37619b-1e62-4651-b39e-c170e055e181/2026-07-10/skills/video-to-semantic-content.md),
this verbiage × the 5 videos is the **semantic model** the site projects.

## The product, in the source's own words (verbatim)
- **realtime.earth:** *"turns every camera, sensor, and GPS device into a shared, georeferenced layer of situational awareness."* It determines a camera's location, direction, and target; **georectifies pixels to real-world coordinates** (lat/lon/alt); and annotates features alongside forecast boundaries, weather, GPS positions, and asset locations.
- **alert.live:** *"applies the same georectification technology to emergency events."* Workflow: **citizens/responders receive text alerts with web-map links centered on their location**; they can **open phone camera feeds that are georectified in real-time for annotation**; layers can be **private, group-shared, or public**; **2D↔3D transitions** for spatial understanding.
- **Simtable** (the tangible sibling): *"a tangible computing surface that runs wildfire and flood simulations on real terrain at the speed of touch."*
- Broader realtime.earth applications named: *"concerts, sporting events, field research, construction, agricultural operations, or community gatherings"* + emergency response (wildfire, flood).

## The 5 videos (embed via YouTube; use as the site's evidence)
| # | Title | URL |
|---|---|---|
| 1 | U.S. Senate Committee on Energy & Natural Resources — Wildland Fire Technology Expo | https://youtu.be/zH93Nyg8h7Q |
| 2 | 2019 Maria Fire: Applying Realtime.Earth and Alert.Live | https://youtu.be/aJpgDzFhXng |
| 3 | Adams Fire 2020: Fire Progression Monitoring with Realtime.Earth | https://youtu.be/lP7-UhZQ4IY |
| 4 | Partners Promoting Interoperability | https://youtu.be/RtDl8URiBHQ |
| 5 | 2020 LNU Lightning Complex: Visual Investigation of Lightning Starts | https://youtu.be/oVAwvs4k1n0 |

Embed form: `https://www.youtube.com/embed/<ID>`. **#2 (Maria Fire)** is the clearest "alert.live in the field" story; **#1 (Senate Expo)** is the credibility/authority piece; **#3 (Adams)** and **#5 (LNU)** are fire-progression / investigation proof; **#4** is the interoperability/partners angle.

## The wedge (why now) — from the strategy demand ranking
The #1 demand in the internal [strategy note 05](https://redfish.acequia.io/guerin/.agents/aa0ecff7-3f7f-48b5-ac49-bb7b4be3270a/2026-07-10/notes/05-demand-side-pull-ranking.md) 🔒 is *"We are blind for the first three hours of an ignition."* When a fire starts, agencies, citizens, and even the big predictive vendors have **scarce, dirty data exactly when decisions matter most.** alert.live's differentiation is **reality capture from the people already on scene** — the operating picture built from live phones + cameras + sensors, georectified. (Marketing-usable positioning only; confidential M&A specifics stay in the internal bead.)

## Assets we already hold (realtime.earth backbone)
AlertWest / ALERTWildfire camera archive + STAC pipeline ([`alertwest-record` 24882a83](https://redfish.acequia.io/guerin/.agents/24882a83-509b-4a9b-8608-303726c0c624/about.md)); the incident-viewer / camera-grid / image-pose lineage (georectification math, camera-as-pose, splats). The site can honestly claim a working substrate, not vaporware.
