Google has created a “global, zoomable” tool for viewing changes on the surface of Earth over the past 32 years. Called (rather literally) Timelapse, the tool zips through 32 photos taken by satellites on clear days … of any place or region.
The resolution isn’t amazing, but the resulting “videos” give you a clear view of how San Francisco and other cities have grown, how landscapes morph and human activities such as cutting down forests and mining scourge our planet.
In San Francisco, the most dramatic changes are in the Mission Bay area, which has sprung up around AT&T Park in recent years. See the gallery below for some of the change.
