# HPWREN Fire-Origin Points — development eval set

Human-placed **fire-origin points** (the base of the smoke column — the point that feeds
azimuth / geolocation) on **confirmed-wildfire** frames from HPWREN fixed cameras.
31 frames spanning ~31 distinct fires.

## ⚠️ Provenance & license
The **images** are HPWREN wildfire-camera frames annotated with smoke bounding boxes by
**[AI For Mankind](https://github.com/aiformankind/wildfire-smoke-dataset)**, released
under **CC BY-NC-SA 4.0**. This dataset **redistributes a curated subset of those images
under the same license** — *attribution, non-commercial, share-alike*. Please credit
**AI For Mankind** and **HPWREN**. The **fire-origin annotations** are the contribution
added here (also CC BY-NC-SA 4.0).

## Columns
`image`, `annotated` (overlay: GT box + origin crosshair + uncertainty region),
`x_origin`/`y_origin` (normalized origin), `x_min…y_max` (2D uncertainty region),
`base_occluded`, `confidence` (clear/moderate/guess), `outside_box` (+`outside_dist`,
derived), `box_*`, `plume_size`, `scene`, `camera`, `annotator`.

## Curation
744 AI For Mankind frames are FIgLib ignition *sequences* (many near-identical frames
per fire). We deduplicated to unique fires (camera + date-region hashing), then
hand-curated — best frame per fire, dropping non-fires — to ~31 confirmed fires.

## Intended use
A **small dev/eval set** for fire-origin estimation methods (bbox-center baseline,
classical CV, SAM). **Not a benchmark** — small N, single region (Southern California).
Non-commercial research only.
