Although these images update regularly, you typically won't see live changes, and there may be a lag of up to a few years between the satellite image you see on your screen and the the way a location looks in real life.You can't predict when a map will change, but you can get help from Google Earth to find out the date of its last update.Like all cities, these four are constantly changing, so you can imagine keeping our 3D up to date in dynamic places like these can be tricky!

If you're browsing Google Maps in Satellite View, you may notice that location details are not always up-to-date.

Google Maps uses the same satellite data as Google Earth.

There are times when Google Maps updates in real-time to mark major events and to give assistance in emergency situations.

For example, it updated imagery for the 2012 London Olympic Games just before the Opening Ceremony, and it provided updated satellite crisis maps to help aid teams assess damage and target locations in need of help shortly after the Nepal earthquake in April 2015.

According to the Google Earth Blog, data updates usually happen about once a month, but they may not show real-time images.

Google Earth gathers data from various satellite and aerial photography sources, and it can take months to process, compare and set up the data before it appears on a map.In Google's case, the imagery is used for a simpler purpose.Still, it's endlessly fascinating to scour the globe from the distance of an orbiting satellite, and the view has never looked better.By stitching together selective portions of the Earth with clear skies, Google's mosaic is able to eliminate clouds and other weather obstructions to create a crystal-clear snapshot of every corner of the world.Google Maps and Earth's satellite imagery was last updated in 2013.Satellites capture images at different resolutions. Landsat, for example, images huge areas at a relatively low resolution of 30 meters — great for viewing large areas like the Amazon. And how do you take those images and build that seamless globe?
