What's in it
- Data offered docs-verified
- terrain elevation slippy-map tiles (zoom 8, 10 resolutions each) · summit heights from OSM natural=peak/ele, pinned to tile model maxima
- Coverage docs-verified
- Global ASTER GDEM v3 base, with higher-resolution national models for Switzerland and Liechtenstein, Bavarian Alps, French Alps, Austria, Italian Alps and northern Italy, and the USA (conterminous, Hawaii, Puerto Rico, surveyed Alaska)
- Resolution docs-verified
- Zoom 8 tiles, ten resolutions each; US 3DEP read at 2/3 arc-second, area-averaged to tile resolution; US heights rounded to a 4 m step
- Formats docs-verified
- tar.gz
- Access docs-verified
- Open download with no authentication (not gated or private); packaging and processing licensed under Apache-2.0; upstream source references must be kept on redistribution
Useful for
- Use cases llm-inferred
- Preliminary terrain and slope screening of Alpine or US project sites before survey · Coarse DEM input for catchment delineation in US or Alpine study areas · Summit and ridgeline height reference for visual or planning context appraisals
- Audience llm-inferred
- hydrologists · GIS analysts · civils engineers · planners
Limitations
- Constraints llm-inferred
- Terrain is resampled, blended and re-encoded; no agency has approved the result and none gives a warranty for it · US tiles are stored as lossy JPEG with heights rounded to a 4 m step (NAVD88) · Outside the listed national model areas, terrain is ASTER GDEM v3 only · No UK coverage is listed, so UK sites would rely on the ASTER base · Upstream licences differ (ODbL for OSM summits, CC BY 4.0, swisstopo terms, Etalab Open Licence 2.0, public domain for 3DEP) and their attribution must be kept · The Hugging Face dataset viewer is unavailable, so the split preview does not work · No time span, source vintage or update cadence is stated · Total download size is 20.8 GB
