+WALOUS land-cover rasters retain EPSG:3812, their native 1 m source resolution,
+the derived analysis resolution, source checksum and exact observation range.
+The governed class domain is `{1,2,3,4,5,6,7,8,9,80,90}`. Codes 80 and 90 are
+valid official low-woody-cover classes; `10` and `11` are not substitutes.
+Bounded derivatives use `uint8`, nodata 255 and nearest-neighbour resampling.
+Area metrics group forest/tree cover as `{8,9,80,90}`, water as `{5}`,
+artificial cover as `{1,2,3}`, rotating herbaceous cover as `{6}`, continuous
+herbaceous cover as `{7}` and bare soil as `{4}`.
