Going back in time with Google Earth (part one: how to)

Posted by rosiemacalpine on February 9, 2009

Google Earth have released a significant new update which has some lovely new features (which all look fab on a IWB). To get the new update, go to the Tools menu in Google Earth and choose Check for Updates Online. Click the download button in the dialogue box which will take you to a web download. Once it’s downloaded, restart Google Earth.

One of the new features that I really like is the historical imagery feature. When you click on the clock button you get a sliding scale and you can explore the satellite imagery for different dates. So far, I’ve just seen dates ranging from 2002 – 2009, but apparently some parts of the US include imagery as far back as the 1950’s.


I then used this feature in a flipchart, so it was easier to compare the views. Promethean Activsoftware includes a feature called Magic Ink which allows you to see through a picture to see another picture hidden underneath. I used the camera tool to take snapshots of each view in of the map.

Then I stacked the pictures on top of each other (2009 picture on top) put the latest view on the top layer and then added a magnifying glass to see through to the 2003 layer. Look carefully at the magnifying glass in the picture. You will see half of a building in the magnifying circle (2003) which had been demolished in the rest of the picture (2009). image

I think this feature works really well as it allows you to directly compare different parts of the picture.
There’s a good post on the new features in this Google Earth version at the Google Earth blog.

If you have Activstudio or Activprimary software, you can download my flipchart showing this feature here.
