This is how the screen will look when you open up Google Earth app or plugin.
Perform searches from the search box at the top left side of the program.
You can type a place name, zipcode or postcode, a town/city name, an airport or you can even try to type in a latitude-longitude location (in decimal format). Once you press the ↵ Enter key, you'll be "flown" to that destination. You can take a virtual holiday!
You can also drag the little yellow man icon to the map and you will get to see street view. I do this before I visit a place so that I can navigate the place easily when I am there!
Use the zoom out and zoom in options from the buttons on the right hand side of the screen.
Turn the wheel in the top right corner to spin the item to a better understood angle.
Click on Exit Street view to go back to the map.
Look for the date the picture was taken from the bottom left hand corner of the screen.
Scroll through the dates to see all the satellite images from different days of the year.
Zoom to a place on the map where the satellite image has a date, click the "View" menu from the menu bar and click the "Historical Imagery" button to enable the feature.
Drag the location of the toggle slider switch in the top left corner to a different date and see what the area was like. e.g. you can see what New Orleans was like after Hurricane Katrina, or one of the many famous historical times that date back to 1990!
Use the Layers button from the bottom left hand side of the screen.
