Derived fields include geodetic latitude/longitude, surface height above the geoid, solar/sensor viewing angles, land/water mask and quality flags. Nominal pixel sampling is not image GSD or a geolocation-accuracy guarantee; catalog GSD is unspecified. This coordinate reference is not calibrated radiance, a new DEM, active LiDAR or radar. Match platform, acquisition time, band group and compatible processing version before associating internal arrays. Apply publisher calibration/geolocation and quality guidance. Native granule polygons and acquisition intervals stay intact; the viewer does not enumerate every internal science pixel or establish valid observations everywhere. Only requested metadata pages are indexed; NetCDF files remain remote and historical archive registration does not guarantee current delivery.","tasking":false,"tier":"preprocessed","title":"VIIRS/JPSS1 Moderate Resolution Terrain Corrected Geolocation L1 6-Min Swath 750m"}],"returned":13,"total":13}
