1 Google Earth 101 A lesson about the basics of the Google Earth program, and how to use it with the REAL storm surge visualization tool.

2 How does Google Earth Display Maps? Using sets of information called LAYERS

3 Earth view with NO LAYERS selected. (This is a bare map) Earth view with Borders and Labels LAYER selected. (This is a map with one layer) In Google Earth, LAYERS are sets of information that you can stack onto your map.

4 Google Earth Basics This is a map of the northern Gulf of Mexico without any layers.

5 Selecting LAYERS by clicking the boxes can let you see sets of information at the same time. They stack on top of each other like a set of transparencies.

6 Select the Places Roads and Weather LAYERS and you can read a current weather map using major roads for reference. BUT BE CAREFUL!...

7 Too many layers = TOO MUCH INFORMATION If too many map layers are turned on, it can make the map unreadable! Be sure to turn on only the layers that you need!

8 Google Earth Basics Turn layers off by clicking the checked boxes. To remove all layers, click the Primary Database box. To turn off Tour Guide across the bottom of you map, click on the double down arrow just to the left of the title.

by clicking on the symbol. If a layer box has a check mark, all sublayers are turned on your the map.

9 All Borders and Labels layers on SOME Ocean layers on, but not all All of the sublayers in the Ocean layer are turned on and visible If a LAYER is marked with a [+] or a, you can expand the selection to see a subset of layers by clicking on the symbol. If a layer box has a check mark, all sublayers are turned on your the map. If a layer box is filled in with a color (usually green or blue) the means that only a selection of sub layers are turned on for your map.
