Landsat / Sentinel global mosaic automatic switcher

Recently Google added to Google Earth global mosaics of Landsat and Sentinel 2 imagery for each year between 1984 and 2016. (1984 was originally omitted but has since been added). We then released a KML file that allows you to animate the imagery by means of a dynamic tour. However, sometimes it is more useful to be able to switch directly between 1984 and 2016 to see the dramatic changes between those dates. So, today we are releasing a slightly modified version that does just that.

Simply open this KML file in Google Earth. Then switch to ‘historical imagery’ and find a location of interest, then play the ‘Switcher’ tour found in the KML. If you wish to move to a different location, close the tour, move to the new location, wait a moment, then open it again. For best results set the tour to auto-repeat.

    I’ve been looking at Google Earth for over 2 years now, and I am wondering WHEN you are going to update the street-view photographs. I have been looking at my own house, whose picture has not been updated since before I bought it over 2 years ago.

  2. Google only cares about the smartphone crowd much like Microsoft. MS fired all their PC workers back in 2011 or something like that known as the Microsoft Shakeup.

    Google abandoned the PC market and are just chasing the smart phone women who only want to shop and dine.

    They really wouldn’t know how to navigate street view nor give a rip unless they were lucky enough to have someone show them then they can teach others.

    Unless it concerns their social life about boyfriends or girlfriends most girls would rather do what’s *trendy* or *cool*.

  3. Oh and that’s why Google search is sucky and you have to be very exact when you type or you will get search results catered to that crowd.

    Google uses Watson AI to guess your search based on most popular queries and it’s that crowd demographics that they target. You are an outlier kinda like the *Drunk GFS* weather model when it shows stupid stuff in the medium range forecast before most people are aware.
