# Bangka Island 1930s Historical Topographic Map Dataset (176 Sheets)

Georeferenced raster dataset of the **1930s Dutch Colonial Topographic Map Series of
Bangka Island** (KK 083-04-01 / 085-04-10), in **WGS 84 (EPSG:4326)**. Intended as a
ground-truth base layer for deep-learning / computer-vision analysis of historical land
use and long-term deforestation.

Code, methodology and full technical report:
**https://github.com/atlganibrahim-glitch/bangka-historical-gis-dataset**

## Contents

| Folder | Sheets | Description |
|--------|--------|-------------|
| `GEOREF_FINAL_STANDARD_164/` | 164 | Single-cell georeferenced GeoTIFFs (one 5′×5′ graticule cell each) |
| `GEOREF_FINAL_COMPOSITE_12/` | 12 | Composite georeferenced GeoTIFFs (two adjacent cells, coastline sheets) |
| `main maps/` | 176 | Raw scanned sheets (source input) |
| `recovered_maps/` | 176 | Cropped images (legend removed), input to georeferencing |

All georeferenced outputs are **EPSG:4326** GeoTIFFs. The 164 single-cell sheets tile
seamlessly (grid-origin scatter σ = 0.0000′).

## Usage

```python
from huggingface_hub import snapshot_download
path = snapshot_download(
    repo_id="ibrahimatlgn/bangka-1930s-topographic-maps",
    repo_type="dataset",
    allow_patterns=["GEOREF_FINAL_STANDARD_164/*"],  # e.g. only the standard sheets
)
```

Open the `.tif` files directly in QGIS (`Add Raster Layer`) — they land in their
real-world position automatically.
