Selected pages feature opportunities to use Earth Engine, an easy to use Google-sponsored web tool, to further explore the history of the landscapes featured on these pages. Earth Engine is a timelapse series of Landsat images gathered between 1984 and 2018, offering a 34-year record of environmental change around the globe. This interactive feature enables users to take a closer look and increase their understanding of the human impact on the Earth.

To access this feature, you will need to use the Chrome browser, as the search function is only activated there. Go to https://earthengine.google.org, click on the Timelapse tab, and enter a place name in the search box at the top. (Suggested place names are offered for SceneChanges pages.) The screen will zoom to your location and present the timelapse images as a slideshow (click the Play arrow), or you can click through them manually. The scene can be dragged and zoomed in or out, and the speed of the slideshow can be changed by clicking on the box at the right end of the timeline and choosing 1x for Fast, 0.5x for Medium, or 0.25x for Slow.

SceneChanges is currently undergoing a substantial updating, as the Earth continues to change, due in large part, in this age that we now call the Anthropocene, to the ongoing activity of its human inhabitants. Check back frequently to see the latest updates.
