1.04 Drawing polygons -- making boxes in google Earth
Wednesday, December 10, 2008 (updated May 27, 2010)
This video overlays the first polygons on the landscape as seen in Google Earth.
Note: Since this the original set of tutorials was written, we’ve learned of a tool on the GPS Visualizer website (on the Calculators page) that helps you make range rings around a location. Range rings are circles drawn on a map to show, for example, everything within a radius of 100 kilometers. You may find it helpful to draw your squares by first drawing range rings and then inscribing them.
Plug in your latitude and longitude which you can see in the bottom of your Google Earth window. You can change how latitude and longitude are displayed (i.e., decimal degrees or degrees, minutes and seconds) through the preferences in Google Earth. Once you’ve entered the latitude and longitude, you can copy and paste in the following series to give you the circles: .05km, .5km, 5km, 50km, 500km, 5000km. Click “Draw map” and the Google Earth or Google Map will be ready nearly instantly.
I’ve created new videos, and replaced the original tutorials for this step and the remaining steps. This new video is posted on youtube. You may find it helpful to view it full screen -- double click on the video to go to youtube to do so.
The updated video also references a key board shortcut for Google Earth. You can find a list of shortcuts here.
The specific short cut referenced is “command-i”. This is the the “Get info” command on the Mac. It’s called “Properties” on the PC. On either operating system, you can find this in the “Edit” menu or in the pop-up menu that appears when you right-click on an item.
