What’s it all about?
Maps on the internet have become incredibly sophisticated. While years ago, it was possible to ask for driving directions from New York to London and get instructions such as:
Swim across the Atlantic Ocean 3462 mi
this just doesn’t happen as often. Although you should always do a sanity check on any driving directions, it is possible to get fairly exact maps and instructions.

Google Earth combines the power of Google Search with satellite imagery, maps, terrain and 3D buildings to put the world’s geographic information at your fingertips.
- Fly to your house. Just type in an address, press Search, and you’ll zoom right in.
- Search for schools, parks, restaurants, and hotels. Get driving directions.
- Tilt and rotate the view to see 3D terrain and buildings, or look up to explore the sky
- Save and share your searches and favorites.
- And if you’re planning a trip to Disney World, the entire park is there, down to the bench by the fountain!
Try it out!
First, you’re going to find out if someone’s already downloaded and installed Google Earth. Click on the Start Menu and look at Programs. Google Earth will be there if it’s installed on this computer.
If it’s not there, you’re going to download Google Earth http://earth.go And yes, IT says that this is ok!

You’ll get a little beep from your computer and a message across the top of the screen.
Click that top bar and select download file.
And select RUN from this message.

Once Google Earth is loaded, it will stay on that computer until someone uninstalls it.

Start Google Earth (START>PROGRAMS>GOOGLE EARTH)
Take the tour or use the Tutorial: http://earth.google.com/intl/en/userguide/v4/tutorials/navigating.html

Fly to: type in an address (your home address or any other) click on the magnifying glass or press enter.
What’s really wonderful in Google Earth is that the mapping understands our ferry system! It knows that to go from Mukilteo to Clinton, you cross the water.

Other mapping programs would have you drive around and cross Deception Pass!
Or try finding places: click on Mt. St. Helens (or any other location) in the list of places.

You’ll navigate on the maps by choosing to move North/South/East/West (Up/Down/Right/Left) using the compass on the right hand side. You can zoom in and out using the + and - signs.
If you’re a map lover, you’ve now found your new playground. Explore, look around, try things.
Geotagging means that you’re assigning a geographic location (usually by longitutde/latitude) to a website, image, or even an RSS feed. You can explore geotagging in many of the photoservice websites, such as Flickr or Picasa.
What did you think?
Google Earth is more than just an maplover’s playground. It’s a great reference tool for maps, directions, or vacation planning.
Write a post to your blog and talk about your Google Earth experience? Did you find what you were looking for? What surprised you about the program?
