Using Google Earth Pro

There are many commercial aerial photograph suppliers which will provide copies of historical aerial photographs for a fee. In addition, free copies of historical satellite/aerial photographs can be obtained from Google Earth Pro which can be downloaded from You should download the desktop version onto your computer, rather than use a tablet or phone version as the tablet/phone versions do not have the historical image facility.

Tap on the clock symbol on the bar at the top and a date slide will appear. Move the date slide to find the year you are interested in. 

Google Earth Pro will then display an image taken that year and month or, if it does not have an image taken that month, it will display the most recent image taken before that month.

As shown above the image will have an imagery date displayed at the bottom in American date mm/dd/yyyy format and the slide at the top will have a month and year in mm/yyyy format. The date that the image was actually taken will, according to Google, be somewhere between these two dates. So in the example above the date the image was taken will have been between 5th March 2008 and 30th September 2008. One reason why you only have a date range rather than a precise date is that a " zoomed out" image may consist of multiple satellite or aerial photographs taken over a period of days or months. Another reason is that Google gets its images from a number of different suppliers and some suppliers may not have recorded precise dates for each image but only an earliest and latest date for a batch of images, so, for example, if the supplier's records only record that a batch of images was taken in the year 2005, the imagery date will be shown as 1/1/2005 for a slide date as 12/2005.

Google is adding to the number of images it is licenced to display all the time and Google Earth only displays one image per date range. Consequently it is possible that an image displayed for any given history slider position may change over time. So if you find an image which shows some detail you are interested in, be sure to save a copy - don't rely on exactly the same image being available the next time you use Google Earth Pro.  

It is possible to save the image by selecting File and Save but it is generally better to instead take a screenshot 
because a screenshot will include the date of the image. To take a screenshot, tap the email symbol at the top, select "screenshot" and tap "Email" and an email will be created with the screenshot as a JPG attachment. You don't actually have to send the email: you can simply save the JPG attachment to your computer with a descriptive name commencing with the year - e.g.
