# 🛰️ CritterScope

Turn a drone survey into **georeferenced animal/object detections on a 3D map.**

A drone flies a survey → thermal+RGB frames + telemetry → an AI detector emits
warm-blob detections → each is projected onto terrain as `(lat, lon, type,
confidence, temp, time)` → this app plots them on a 3D terrain globe with a
timeline you can replay.

The dashboard runs **today** off a built-in simulator, so the whole UI is done and
testable before any drone arrives. Real footage feeds the *same* dashboard via
`POST /api/ingest`.

## Stack
- **Cloudflare Worker + Hono** (`src/index.js`)
- **MapLibre GL JS** — satellite imagery + Terrarium DEM for real 3D terrain (no API key)
- **D1** (optional) — stores real surveys/detections; schema in `schema.sql`
- Deploys to `critterscope.theradicalparty.com`

## Run locally
```bash
npm install
npm run dev            # http://localhost:8787
```
Open `/` for the dashboard. Point it anywhere:
```
/?lat=-33.73&lon=150.31&r=1000        # center, radius (m)
/?seed=42                             # different simulated survey
```

## Data contract (what the drone pipeline must produce)
`GET /api/survey` returns:
```jsonc
{
  "survey":     { "id","name","center_lon","center_lat","radius_m","sensor","drone","started_at","ended_at","simulated" },
  "flight":     [ { "seq","lon","lat","agl_m","t" } ],
  "detections": [ { "id","type","lon","lat","confidence","temp_c","t","frame" } ],
  "stats":      { "total","counts","area_km2","duration_min" }
}
```
`type` ∈ `deer | fox | rabbit | boar | kangaroo | person | vehicle | unknown`.

## Feeding real drone data
1. `wrangler d1 create critterscope`, paste the id into `wrangler.toml`, uncomment the binding.
2. `npm run db:init`
3. `POST /api/ingest` with `{ survey, flight, detections }`.
4. View it at `/?survey=<id>`.

The georeferencing step (frame + drone GPS + gimbal angle + terrain → lat/lon) lives
in the drone pipeline, not here — this app just needs the resulting detections.

## Roadmap
- [ ] Drone ingest pipeline (RTMP/SRT frames → YOLO thermal detector → georeferencer)
- [ ] Live mode (stream detections during flight, not just post-survey)
- [ ] Track clustering (merge repeat sightings of the same animal across passes)
