The Normalized Difference Layer: Sentinel-2 Kochia and UAV wheat archives

Sentinel-2 Kochia archive (2,318 labeled polygon records, one site near Lucky Lake, Saskatchewan, seasons 2022-2024; ten reflectance bands b1-b10 plus two undocumented fields b11-b12 as distributed) and UAV wheat archives (143,989-pixel segment archive with class-qualified segment identifiers across three growth stages, and the spatially blocked companion archive). Spatial group assignments (year, 3x3 spatial cell, year-by-spatial cell; block and plot-cluster IDs) are provided in place of raw coordinates; exact field coordinates are withheld. These are the exact cohorts analyzed in the accompanying article. Per-file SHA-256 checksums included. Funding: Saskatchewan Ministry of Agriculture, Agriculture Development Fund, project 20230164.
