Google Earth Engine & Timelapse

​

Google Earth is great for viewing, but...

...how can we measure �the changes we see?

Earth Engine is...

• Access to over 40 years of Satellite Imagery�(with daily updates)

​

• Scientific algorithms to analyze that data �(as well as your own data)

​

• Google's computer clusters to analyze the data

Raw Landsat Data has clouds and other data issues:

Earth Engine combines multiple images to remove clouds...

We can do it for the whole globe...
