≤ 250 m · raw-code topo, stretched for contrast> 250 m · masked orangeLand type · country context
Choose an elevation cut from 100–500 m. 250 m is the default comparison view. The one-eye view keeps land at or below the selected elevation visible and masks higher land.
Topography is a visual treatment of the compact elevation code; the threshold uses the elevation meaning.
