Introduction to Analyze Data from Images in Google Earth Engine

Studying how the world changes over time can help  you understand what may be causing these changes.  Changes can come about from natural  factors, like wind and earthquakes,  Or from human interaction, such as cutting  down trees to build new structures.  One way to study these types  of changes is to look at   images taken over time.

You can do this  using a tool like Google Earth Engine.  Google Earth Engine uses satellite  images.

Satellites are objects   that have been built to orbit the Earth.

They take pictures of the water and land below.   Then, scientists draw conclusions from the images  to discover how the environments are changing.  One way to understand how environments  change is to look at timelapse images.  Timelapse images are images taken at  regular intervals and then combined.  They help you see how an environment  changes over months, years, or even decades.  Google Earth Engine has many  timelapse images you can explore,   like the construction of the  Berlin Brandenburg Airport,  And the rise of urban growth in Las Vegas.  In this lesson, you will: Choose a timelapse topic in Google Earth Engine,  Take screenshots of any changes  and collect them in a document,  Write a description for each screenshot, And summarize your descriptions.  This lesson uses Google Docs, but you  could apply these skills and concepts   in most other word processing applications.  To work on this lesson, sign in to  your Google account.
