# DEPTH Risk Map

Interactive migration-risk map for Mexico, developed by the University of
Nottingham's Rights Lab. Humanitarian, violence and infrastructure indicators
overlaid on a rHEALPix hierarchical spatial grid.

## How this Space works

- `Dockerfile` builds an R image (`rocker/geospatial`), installs the app
  packages, and downloads `depth_mexico.duckdb` from the
  [`edgarodriguez/depth_alpha`](https://huggingface.co/datasets/edgarodriguez/depth_alpha)
  dataset at build time (baked into the image).
- The Shiny app (`10.11_draw_query_indicators_v10_HF.R`) opens that DuckDB
  read-only and serves on `0.0.0.0:7860`.

## Files

| File | Role |
|---|---|
| `10.11_draw_query_indicators_v10_HF.R` | Shiny app (HF build of v9) |
| `helpers.R` | DuckDB connection + formatting helpers |
| `10.08_styles.css` | App stylesheet |
| `Dockerfile` | Image build + DuckDB bake-in |

## Updating

The app database is not stored in this Space. To refresh data, update
`depth_mexico.duckdb` in the `edgarodriguez/depth_alpha` dataset and rebuild
(Factory rebuild). App-logic changes are made upstream in `v9`, then this file
is regenerated from it.
