USDA NASS Cropland Data Layer (CDL)
Annual USDA NASS Cropland Data Layer (crop-specific land cover for CONUS) as an analysis-ready Icechunk Zarr store. Two groups: 30 m and 10 m (from 2024), each on a single EPSG:5070 grid with a year dimension. Pixels are bit-identical to the official rasters; class names/colors, CRS, citation, and per-year provenance are embedded as metadata. Sharded Zarr v3 layout: field-scale queries fetch tens of KB. US public domain.

USDA NRCS gNATSGO Soil Properties
Soil properties from the USDA NRCS gNATSGO database as an analysis-ready Icechunk Zarr store. 12 regional groups (CONUS, Alaska, Hawaii, Puerto Rico, and Pacific territories) on their native 30 m grids. Depth-indexed soil properties (available water storage, organic carbon, sand/silt/clay, bulk density, ksat, pH, …) on an 11-interval depth dimension, plus 2-D map-unit properties (mukey, NCCPI, root zone, terrain, surface texture). Values are flattened from the release's relational tables by documented, versioned aggregations; units, algorithms, CRS, and provenance are embedded as metadata. Sharded Zarr v3 layout: field-scale queries fetch tens of KB. US public domain.
