Geography 387 – Fall 2011 Lab 9 Exploring the World with Google Earth 1 Lab 9: Exploring the World with Google Earth 1.0 Purpose In this lab we will take a tour of several locations on the earth as a way to explore the functionality of a geobrowswer, Google Earth. Along the way, you may also learn some interesting aspects of current social, political and environmental Geography! 2.0 Preliminary steps Step 1.

In depth information on the application can be found in the Google Earth User Guide. Start by reading the section in the user guide on Navigating in Google Earth . Spend some time learning how to zoom in and out, move the view in different directions, swivel the view aspect, and tilt the view angle. The basics of the Navigation controls are listed below...Geography 387 – Fall 2011 Lab 9 Exploring the World with Google Earth 4 1. Clicking this button resets the view so that north is at the top of the screen. Click and drag the ring to rotate your view. 2. Use the Look joystick to look around from a single vantage point, as if you were turning your head. Click an arrow to look in that direction or continue to press down on the mouse button to change your view. After clicking an arrow, move the mouse around on the joystick to change the direction of motion. 3. Use the Move joystick to move your position from one place to another. Click an arrow to look in that direction or continue to press down on the mouse button to change your view. After clicking an arrow, move the mouse around on the joystick to change the direction of motion. 4. Use the zoom slider to zoom in or out (+ to zoom in, - to zoom out) or click the icons at the end of the slider. As you move closer to the ground, Google Earth swoops (tilts) to change your viewing angle to be parallel to the Earth's surface. You can turn off this automatic tilt (Tools > Options > Navigation > Navigation controls; Mac: Google Earth > Preferences > Navigation > Navigation controls). There is also a good summary video on the navigation controls on You Tube. Step 4. In the Layers window, turn off all layers except Borders and Labels by clicking the check box next to each folder. In the Borders and Labels layer, countries are labeled and have yellow borders and major cities have a clickable red dot icon and a label. Clicking the icon brings up additional information for the city in a pop-up window. Your Layers window should look like this: You are now ready to begin exploring the earth!Geography 387 – Fall 2011 Lab 9 Exploring the World with Google Earth 5 3.0 A tour of the world with Google Earth Location 1 . Place a place mark with the placemark button. You should see a yellow pushpin appear somewhere in Google Earth. In the Placemark properties window, click on the View tab. Enter the following information for name, latitude, longitude and range. You can just copy and paste this information from this lab webpage into the corresponding boxes in the properties window. (Remember: CTRL-C is copy and CTRL-V is paste). Name: Location #1 Latitude: 8°51'35.34"N Longitude: 79°30'38.13"W Range: 5000m Click the "Center in View" checkbox.

Notice that it is in the Temporary Places folder. Drag and drop the Location #1 placemark into the My Places folder. This is preferable as your locations will be automatically saved when in the My Places folder.Geography 387 – Fall 2011 Lab 9 Exploring the World with Google Earth 7 If your view has not already shifted to the new coordinates and view height at 5000m (range), then double-click the placemark in the Places window. You should now have a view focused on a boats in the ocean, similar to that below. Turn on the Photos layer in the Layers window. This will allow you to see georeferenced photographs uploaded by people all over the world through a service called Panoramio. Click on the icons to see these pictures. Use a combination of your zoom and pan tools to observe the mainland of this region. Answer the following question. Question 1: (4) Why are all these large boats concentrated in this part of the ocean?

This will make sure that the next placemark that you make is placed in the My Places folder, rather than the Temporary Places folder. You can also click and drag a placemark from Temporary Places to My Places. Location 2. Now we will visit another location. Make a placemark once again, anywhere in the view is fine, and this time enter the following information. Remember to enter the information in the View tab, not in the latitude/longitude boxes below the placemark name. Name: Location #2 Latitude: 3°56'45.29"S
