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.

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

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
)
