On Thursday May 9th, Time, Google, NASA and USGS released Timelapse powered by Google. You can watch the last 30 years of satellite photography of anywhere on earth. According to Louis Perrochon, "We sifted through 2,068,467 images—a total of 909 terabytes of data—to find the highest-quality pixels (e.g., those without clouds), for every year since 1984 and for every spot on Earth. We then compiled these into enormous planetary images, 1.78 terapixels each, one for each year."
They have selected a few very stunning timelapses for you to view by clicking
here. You can move around the world and zoom in anywhere. This might be an interesting tool in the classroom to look at erosion or climate change. I have zoomed in on the east side of Windsor, east of the WFCU center. You will notice a large rectangular green area gets built up over the last 30 years around the Banwell Hill - St. Josephs area as highlighted in the red box below.
If you would like to watch the development of this area click
here. You can zoom out or move anywhere else in the world you would like. When you are done, if you would like to share the new view, click on the icon that looks like this
