Historical source catalog rasters were individually locked by object ID and exported as GeoTIFF at these bounds; the 2024 frame was bilinearly resampled from the pinned local NAIP GeoTIFF. Display WebP files are unannotated and have no embedded georeferencing. The 2014 historical service marked a tiny ocean/outer-fringe fraction transparent while retaining RGB values; mask inspection found only two marked pixels in the central Ranch context.",

Verify specific reuse terms before redistribution outside this local board briefing.",
  "dateEvidence": "For 2009\u00e2\u20ac\u201c2022, the acquisition date is the first YYYYMMDD embedded in the USDA NAIP catalog tile name, distinguished from the second YYYYMMDD (image creation date) where present; see USGS NAIP data dictionary https://www.usgs.gov/centers/eros/science/national-agriculture-imagery-program-naip-data-dictionary. 2024 QQDATE in USDA's catalog and the pinned local tile name agree.",
  "coverageNote": "USDA's Ranch-area catalog returns dated 1 m quarter-quad tiles for 2010 and 2012, which fill the earlier briefing's 2009\u00e2\u20ac\u201c2014 gap. Its 2011 and 2013 services returned only coarse 8 m mosaic entries at the same point, not individually dated high-resolution Ranch tiles; those years are not presented as observations. This is a set of available flights, not annual monitoring.",
  "comparisonCaveat": "Only visual comparisons of dated orthoimagery are supported. Season, illumination, exposure, color processing, shadows, native ground sample distance and small orthorectification offsets differ. Apparent cover changes are not quantified canopy loss/gain or species identification, and these frames cannot establish planting boundaries or later-than-2024 conditions.",
