Google Earth shows the best map imagery available for the area viewed. Historic imagery, available for many areas, is viewable instead of the most recent or best aerial photography. Availability and time lines vary by place, but you can easily view changes based on the years. Although there are several methods to access the imagery, Google Earth has a feature to alert you when historic imagery is available for the area you’re viewing.
Difficulty:Easy1
Zoom in to the desired area. As you zoom in, check the “Imagery date” information located at the bottom left corner of the map window.
2
Click on the button showing the year located to the right of the “Imagery date” notice. If historic imagery is available for any of the viewable area, the date button shows the year of the oldest available photography.
3
Slide the time line tool, which opens once you click the year button, to view all available photography by date.
You can also click “Historic imagery” in the “View” menu or click the clock icon on the map menu bar to open the time line.
