TerrariumElevationProvider Class Reference

AWS Open Data Terrain Tiles (Mapzen/Tilezen terrarium encoding). Standard slippy z/x/y PNG tiles, zooms 0-15; height = (R*256 + G + B/256) - 32768 meters. GeoMap-only: not user selectable, so the shared terrain pipeline never sees it. Attribution (required when surfaced in UI): Terrain Tiles by Mapzen/Tilezen — SRTM (NASA), 3DEP (USGS), GMTED2010 (USGS), ETOPO1 (NOAA), and other sources. https://registry.opendata.aws/terrain-tiles/.
