    dct:description "Lake water-level time-series artifacts from satellite radar altimetry, located by publisher point geometries. Heights use the EGM2008 geoid; each GeoJSON artifact can contain multiple observation dates and uncertainties. These points are not terrain grids or lake extent polygons. These are observations or derived estimates, not weather forecasts. Published cadence is distinct from continuous real-time availability." ;
