FABDEM v1.2 — Cloud-Optimized GeoTIFFs

Bare-earth 30 m global DEM: Copernicus GLO-30 with forest and building height biases removed by the University of Bristol. This bucket hosts the tiles rewritten as valid COGs with internal overview pyramids, plus a static STAC catalog describing them.

Raster profile

Float32 elevation in metres, EPSG:4326, 3600 × 3600 per tile (~1° × 1°), nodata −9999. DEFLATE with predictor 2, 512 × 512 internal tiles, overview levels 2/4/8 built with average resampling. Pixel values are identical to the source tiles — the rewrite only changed the container.

Access

Files are readable directly over HTTPS, no authentication:

https://huggingface.co/buckets/links-ads/fabdem/resolve/tiles/<group>/<tile>.tif

which works with GDAL as /vsicurl/<url>:

import rasterio

url = "https://huggingface.co/buckets/links-ads/fabdem/resolve/tiles/N00E000-N10E010_FABDEM_V1-2/N00E006_FABDEM_V1-2.tif"
with rasterio.open("/vsicurl/" + url) as src:
    print(src.overviews(1))  # [2, 4, 8]
