These files were changed from the originals:

  - Converted from GeoTIFF to Cloud Optimized GeoTIFF with GDAL 3.9
    (DEFLATE compression with a predictor, 512 x 512 tiles, overviews).
    The overviews are new, averaged or resampled images added for display;
    they are not part of the original data.
  - No pixel value of the full-resolution image was changed. The size,
    coordinate reference system, geotransform, data type and nodata value
    are the same as in the originals. See README.md for the checks, the
    source URLs, dates, sizes and sha256 sums (manifest.json has them for
    every file).
