What's in it
- Data offered docs-verified
- NLCD 2024 land cover as continuous coverage fractions per H3 cell · 20 per-channel land cover fraction columns (raw_11_open_water to raw_95_emergent_wetlands) · centroid_lat and centroid_lon per cell
- Coverage docs-verified
- Conterminous United States (CONUS) · 2024 (NLCD 2024 source year)
- Resolution docs-verified
- H3 resolution 10 (docs give ~15,000 m² per cell and ~120 m edge; see limitations) from 30 m NLCD source
- Formats docs-verified
- GeoParquet
- Access docs-verified
- Open: CC BY 4.0 licence; no auth listed (ENTRY auth: null)
Useful for
- Use cases llm-inferred
- Join per-hex NLCD developed-land fractions to other H3-indexed US datasets for stormwater or impervious-cover screening on US projects · Wetland and forest fraction screening (woody and emergent wetlands, forest classes) for US ecological baseline or habitat connectivity work · Pre-computed land cover features for US catchment or site-level modelling inputs where NLCD is the chosen source
- Audience llm-inferred
- GIS analysts · ecologists · hydrologists · drainage engineers · planners · data scientists
Limitations
- Constraints llm-inferred
- Conterminous US only per docs; ENTRY regions says 'Global', which conflicts with the docs. No UK coverage for a UK-focused catalogue. · Docs state ~120 m edge alongside ~15,000 m² per cell; a regular hexagon of that area has an edge of about 76 m, so the edge figure looks inconsistent. · Values are continuous fractions, not discrete classes; users must threshold or interpret them. · Several channels (dwarf scrub, sedge, lichens, moss) show a max of 0 in the viewer schema and are effectively empty. · Very large (523M rows in the train split); practical use needs Dask, Polars or similar. · Single NLCD 2024 snapshot; no temporal series documented. · feature_count appears in the schema but its meaning is not documented. · Community upload under an individual Hugging Face namespace, not an official USGS/MRLC release; it is a derived product, so verify against the NLCD source. · Delivered as one file per state (data/{state}_Res10.parquet), so multi-state work needs file handling.
