The app displays a timeline and list, letting you browse all archived versions based on location and scale. The app also supports saving a web map from selected imagery, using swipe to compare imagery of different dates, and also animating imagery over time.

There are two ways that you can leverage Wayback imagery using the online archive, or using the Wayback app. Note that this archive is based on the date that it was published in the World Imagery basemap, not on the date the imagery was actually acquired, which may differ. The different vintages of imagery are published as tile layers that you can add to your maps or can use as basemaps. Wayback Imagery is a digital archive of the World Imagery basemap that enables you to access over 150 versions of World Imagery captured over the past 8 years.

Another reason is that you may want to go back in time to view change that has occurred as the result of development, fires, or other events. In these cases, you may want to access a previous version of the World Imagery basemap or layers. For example, the previous imagery may better align with your GIS layers, or may offer fewer shadows, clouds, or snow cover. In the vast majority of cases the updated imagery is better, more recent, and is preferred, but there may be exceptions. When and where updates occur, the previous imagery is replaced and is no longer visible. The World Imagery basemap is updated regularly with newer imagery.
