Description

The Earth Timelapse dataset provides a four-decade visual record of planetary change spanning from 1984 to 2022. 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.

See the Timelapse developer documentation for more details on data characteristics, processing, and limitations.
