Google Earth has a ton of amazing features, but at the core of all of them is the base layer of imagery. While that aspect of Google Earth is somewhat taken for granted these days, it is still amazing that they’re able to produce and distribute such a massive amount of data for all of us to use.
We often get questions about the process of how Google takes the imagery from satellites and makes it available for us in Google Earth, and I’ll refer you back to Frank’s excellent post from a few years ago where he explains that process in a great deal of detail.
You’ve probably also noticed that Google displays dates on all of their imagery, but you may be surprised to know that the dates aren’t always exact. Here is a post that explains exactly what those dates mean and how to interpret them.
Nearly two years before Google Earth was first released on Android, Google brought it to the iPhone. The initial release was quite impressive, and subsequent versions 2.0 (with “My Maps” support), 3.0 (with iPad support) and others have only made it better. The latest release for Android (version 7.0 with 3D imagery) should be arriving on iOS very soon.
