  "method": "Classify full-resolution JPEG pixels by source legend colors; map water, vegetation/relief, sand, urban ground, buildings, road and pavement to a muted atlas palette. Suppress colored annotations with bounded adjacent surface samples. Downsample each tile 2:1 with Lanczos. Assemble by exact canonical world registration. Replace source water texture with uniform blue and a source-land-mask Gaussian proximity halo (sigma 28 raster pixels / 112 world units), a decorative coastline emphasis, NOT depth or bathymetry. No fabricated land or road geometry. No elevation.bin used.",
