Common questions about Google Earth
Prior to Demo –
1. When were these pictures taken? How often are they updated?
Insure proper system set-up
Detail should be set at Medium
Graphics Mode – Open GL
Cache setting – Disk Max 2000
Touring – Don’t fly too fast (1/3 speed) it can create motion sickness
Navigation Screen Shot – User Based is best mode – Note these options
were specifically developed for 3Dx controllers by Google
Our images are photographs taken by satellites and aircraft sometime in
the last three years. The images in Google Earth are updated on a rolling
basis. Click here for more details.
2. Are Google Earth images captured in real time?
No, they aren't. Our images are photographs taken by satellites and
aircraft sometime in the last three years.
3. Are there cities covered in detail worldwide? Or just in the US?
The whole world is covered with medium resolution imagery and terrain
data. This resolution allows you to see major geographic features and
man-made development such as towns, but not detail of individual
buildings. Additional high-resolution imagery which reveals detail for
individual buildings is available for most of the major cities in the US,
Western Europe, Canada, and the UK. 3D buildings are represented in 38
US cities (the major urban areas). Detailed road maps are available for the
US, Canada, the UK, and Western Europe. And Google Local search is
available for the US, Canada, and the UK.
4. Why do I see blurry pictures when I go to my house?
Enabled Control should NOT be selected.
Be sure to practice for a couple of hours prior to demo
Depending on audience, select key areas of interest – Company HQ and their
offices on GE
Select Mountains (Rockies/Alps), Canyons – Grand Canyon are great areas
to demo the 3D capabilities and limitations with just a mouse.
First part of the demo is focused on basic navigation – Pan/Zoom
Second part of the demo is focused on interactive – Pan/Zoom/ Tilt/Rotating –
Navigating in 3D
Google Earth combines data of different resolutions to offer a seamless
viewing experience, and some locations may look a bit blurry. We offer
high resolution imagery (greater than 1-meter per pixel which provides an
aerial view of approximately 1500 feet) for thousands of cities and more
are on the way.
5. Will my computer be able to run Google Earth?
Google Earth takes advantage of the 3D graphics capabilities standard on
most computers. If you are using Google Earth on an older machine, or a
notebook computer that does not have 3D graphics capabilities, you may
not be able to run the application.
image corresponds to the 3D viewer imagery beneath.
When you create an image overlay, you are specifying three important things:
What image file to display in the 3D viewer (from your computer, from your
network, or from a website)
How to fit or position the image boundaries to the earth data beneath
What the location and view of the imagery overlay is (in the same way you
do when positioning a new placemark)
The topics in this section cover:
Creating an Overlay
Opening and Viewing Overlays
Posting Image Overlays to a Web Server
1. Overview slider for selected overlay
Overlay images can be taken from your computer, from your network, or from a
web site. The image format must be:
Note - You can also adjust the transparency of a selected overlay if your mouse
has a scroll wheel. Click the slider (see above). Scroll down to make the overlay
more opaque. Scroll up to make the overlay more transparent, .
You can use topographical maps, weather satellite image maps, or other
geographical image data as overlays. For ideas and examples of overlays, see the
Google Earth Community bulletin board (bbs.keyhole.com).
Transparency Adjustment - You can adjust the transparency of an overlay from
completely transparent to fully opaque whenever it is selected in the viewer. By
adjusting the transparency of the overlay image, you can see how the overlay
When you create an overlay, it completely integrates with the terrain or shape of
the land beneath if the terrain layer is turned on. For example, you might create
an overlay of Yosemite National Park and be able to view the trails in
relationship to the 3D view of the mountains. In this way, the combination of an
overlay map and the 3D viewer imagery gives more information than either one
Creating an overlay
1. Position the 3D viewer in the location where you want to place the
overlay image file.
Try to position the viewer so that it corresponds in viewing altitude to the
overlay. If the overlay is of a detailed view, zoom into the subject area
so that you don't have to make large adjustments later. By contrast, if
the overlay covers a large area, make sure the entire area is
encompassed in the 3D viewer with some margins for adjusting the
2. Select Image Overlay from the Add menu (or use other shortcut
methods described in Creating A New Placemark). The New Image
Overlay dialog box appears.
3. Provide a descriptive name in the Name field.
Overlay map with terrain off
4. In the Link field, enter the location of the image file you want to use as
an overlay or use the Browse button to locate it on your computer or
If the image you are referencing is located on the Web, you will need to
enter the URL for that image file. This is different from the URL for the
web page itself! If you are using Internet Explorer, you can retrieve the
URL for an image by right-clicking on the image on its web page and
selecting Copy Shortcut from the pop-up menu. At that point, you can
insert your cursor in the Image URL or Filename field and paste the
information using Ctrl+V ( on the Mac).
Overlay map with terrain on
The image appears in the 3D viewer, with anchor points that you use to
5. Specify the descriptive information for the overlay. Descriptions for
overlays are identical to descriptions for all places data. See Writing
Descriptions for details.
6. Click the Refresh tab and set the correct refresh properties for your overlay
imagery. The refresh settings for overlays are identical to those described
for network links. Typically, any imagery that is updated automatically and
located on a server will need refresh properties set. For example, weather
satellite image maps will likely need to be refreshed. For details on the
differences between time-based and view-based refresh, see the
description for network links.
7. Set the default transparency for the imagery using the slider. The
transparency setting for image overlays can be adjusted at any time when
you are viewing an overlay. To make it easy to position the overlay, first
adjust the transparency to achieve a good balance between seeing the
imagery and the earth beneath it.
8. When you select the View tab, you can modify the view settings for the
overlay just as you would any place data. See Setting the View for details.
9. Position the image in the viewer to your preferences and click OK to
complete the creation. If you later want to correct the overlay or reposition
it, simply edit the overlay as you would any other places data. See the
topics in Editing Places and Folders for more information.
Positioning the imagery in the viewer
Once you have inserted the overlay image into the viewer, you can use the green
markers to stretch and move the image in a number of ways to get the most exact
positioning required. An overlay image will have corner and edge marks that you
can use to stretch the image, a central cross hair marker to position the image, and
a triangle marker that you can use to rotate the image.
When you select one of these markers, the cursor changes from an open hand to
either a finger-pointing hand or an arrow to indicate that an anchor point is
selected. The following illustration describes the anchor points in detail.
1. Use the center cross-hair marker to slide the entire overlay on the globe
and position it from the center. (Tip: do this first.)
2. Use the triangle marker to rotate the image for better placement.
3. Use any of the corner cross-hair markers to stretch or skew the selected
corner. If you press the Shift key when selecting this marker, the image
is scaled from the center.
4. Use any of the four side anchors to stretch the image in or out of from
the selected side. If you press the Shift key when doing this, the image
is scaled from the center.
Tip - Try positioning the center of the image as a reference point first, and then
use the Shift key in combination with one of the anchors to scale the image for
When you select the Location tab, you can use the following settings:
Manual coordinates for each corner of the image overlay. This is similar
in principle to the manual setting discussed in Repositioning
Placemarks, except that instead of setting coordinates for a single point,
you set coordinates for each corner of the image overlay. You might
want to use this feature if your image overlay comes from a precise map
where the exact coordinates are known.
Draw Order - If you have more than one overlay for a given region, you can
set the draw order for overlays to determine which image is displayed
relative to other images. Overlays with higher numbers are drawn before
those with lower numbers.
Fit to Screen - Click this to resize the image to fit the current view.
When you select the View tab, you can modify the view settings for the overlay just
as you would any place data. See Setting the View for details.
