Synthesized by Google from petabytes of spaceborne observations acquired by NASA/USGS Landsat missions (Landsat 4, 5, 7, 8, and 9) and ESA's Copernicus Sentinel-2 constellation, the dataset is offered as annual mosaics for visual interpretation. The annual mosaics are globally complete, gap-filled, and water-masked visual basemaps that power the public Google Earth Timelapse interactive viewer. Pre-1999 observation voids are smoothly reconstructed using pixel-wise temporal linear regression interpolation across adjacent valid observation years. Open ocean waters are replaced with styled NOAA ETOPO1 shaded-relief bathymetry and global water masking (using Hansen GFC and MOD44W datasets). These data are suitable for: visual interpretation, educational storytelling, base mapping, or custom video exports. > [!NOTE] > **Note:** The RGB bands contain visually normalized 8-bit values derived from Top-of-Atmosphere (TOA) reflectance (contrast-stretched from \[0.02, 0.50\] with gamma 1.7 and matched to a MODIS BRDF baseline), not surface reflectance. Timelapse is not recommended for quantitative radiometric analysis. See [the Timelapse developer documentation](https://developers.google.com/earth-engine/timelapse/about) for more details on data characteristics, processing, and limitations. ### Bands **Bands** Pixel size: 30 meters (all bands) | Name | Min | Max | Pixel Size | Description | |---|---|---|---|---| | `red` | 0 | 255 | 30 meters | Visually normalized 8-bit red value derived from TOA reflectance (min 0.02, max 0.50, gamma 1.7, matched to MODIS BRDF; not surface reflectance). | | `green` | 0 | 255 | 30 meters | Visually normalized 8-bit green value derived from TOA reflectance (min 0.02, max 0.50, gamma 1.7, matched to MODIS BRDF; not surface reflectance). | | `blue` | 0 | 255 | 30 meters | Visually normalized 8-bit blue value derived from TOA reflectance (min 0.02, max 0.50, gamma 1.7, matched to MODIS BRDF; not surface reflectance). | ### Image Properties **Image Properties** | Name | Type | Description | |---|---|---| | year | INT | Observation year of the annual mosaic. | ### Terms of Use **Terms of Use** This dataset is licensed under [CC-BY 4.0](https://creativecommons.org/licenses/by/4.0/) and requires the following attribution: "Google Earth Timelapse (Google, Landsat, Copernicus)" Contains modified Copernicus Sentinel data \[2015-present\].
