Checked facts
Active layer is historical 2025 transit counts, updated from the 2021 raster previously used · NOAA re-hosted years 2019-2025 at coast.noaa.gov/.../MarineCadastre/ (the legacy maps1.coast.noaa.gov/.../OceanReports/ host now serves only the original 2021 layer) · The 2025 layer publishes a differently named pixel-value attribute (Classify.Pixel Value) than 2019-2024 (UniqueValue.Pixel Value); the adapter checks both · Raster cells are 100 m by 100 m · Counts are not live vessel positions · Year and cell size are always shown
