Chapter 2 Where in the Geospatial World Are You?
2. Zoom out to see the whole world—you’ll also see that the graticule has
changed from a Web of latitude/longitude lines to the UTM grid draped
over Earth. You should see the UTM zones laid out across the world,
numbered from 1 through 60.
Question 2.8 What UTM Zone is Buckingham Palace located in? What
UTM Zone is the White House located in?
3. Double-click on the White House placemark (in the Places box) and GE
will rotate and zoom back to the White House.
4. Scroll the mouse around the White House area. You’ll see the new
coordinates appear at the bottom of the view, but this time as the zone,
easting, and northing measurements. Open the Properties of the White
House placemark by right-clicking on it. The UTM easting, northing,
and zone will appear.
Question 2.9 What are the UTM coordinates of the White House?
5. In the Places box, double-click on the Lincoln Memorial placemark and
GE will zoom and rotate to it.
Question 2.10 What are the UTM coordinates of the Lincoln Memorial?
6. UTM coordinates are measured in meters, enabling an easier method of
determining coordinates rather than degrees of latitude or longitude. If
you move the mouse east, your easting will increase, and moving it west
will decrease the easting. The same holds true for northing—moving the
mouse north will increase the value of northing, while moving it south
will decrease the northing value.
7. Change the view so that you can see both the White House and the
Lincoln Memorial in the view. Using your answers for Questions 2.9 and
2.10 (and perhaps the Ruler tool), answer Question 2.11.
Question 2.11 How many meters away to the north and east is the White
House from the Lincoln Memorial?
8. UTM can also be used to determine the location of other objects.
Return to the White House placemark again. Determine what object
is 912 meters south and 94.85 meters to the east of the White House.
Question 2.12 What object is located approximately 912 meters south and
94.85 meters east of the White House?
Question 2.13 What are the full UTM coordinates of this object?
Closing Time
This lab served as an introduction for using and referencing coordinates and measurements using Google Earth. Chapter 3’s lab will use a new software program,
but we’ll return to Google Earth in Chapter 8 and continue using its functions in
other chapters as well. You can now exit GE by selecting Exit from the File pulldown menu. There’s no need to save any data (or Temporary Places) in this lab.
