Google Earth

Google Earth is an entirely new way to view our world.  Zoom in on the Middlebury College campus.

* Requires installation of Google Earth.

Please review the below questions BEFORE downloading the KML file. (Click on the desired heading for answers!)

Why are the images blurry?

The detailed flyover images are not enabled by default, due to filesize and load time considerations. There are two sets of the flyover images which differ in quality. Enable the set that makes sense for your system configuration.

Why do I see the message "Invalid Image Format" when I try to load a flyover image?

The "Invalid Image Format" message is somewhat misleading. Google Earth looks at your system resources and the available space in its memory caches and determines whether it is able to display an image. If your settings are set such that Google Earth is unable to load all of the information, Google Earth reports that you tried to load an image with an "Invalid Image Format".

To fix this issue, make sure your computer meets the system requirements described above and follow the How do I change my Memory Cache Settings in Google Earth guide to adjust the amount of resources Google Earth has to work with.

How do I change my Memory Cache Settings in Google Earth?

To best see the Flyover photos of the Campus and the Bread Loaf Campus in Google Earth, we suggest that you change the memory cache settings in the Google Earth client application. Before adjusting these settings, make sure your computer meets the requirements listed above.

  1. Open the Google Earth application.
  2. Click the Tools menu in Google Earth.
  3. Under the Tools menu, click Options.
  4. Click the Cache tab in the Google Earth Options dialog.
  5. Set the Memory Cache Size to at least one half of your total RAM or system memory. See the sections above to determine your total RAM. For example, if your total RAM is equivalent to the required value of 512 MB, enter 256 MB in the Memory Cache Size field.
  6. Set the Disk Cache Size to at least 1024 MB. See the sections above to determine how much Hard Disk space you have available.
  7. Click the Clear memory cache button.
  8. Click the Clear disk cache buttn.
  9. Click Apply Settings.
  10. Click OK.

Why does my screen flicker when I load a flyover image?

You may have an old version of the Google Earth application or an older release of Version 4. Visit Google Earth's download site to get the latest release of the Version 4 Google Earth application.

If you continue to experience flickering when loading the Flyover photos, follow the How do I change my Memory Cache Settings in Google Earth guide to adjust the amount of resources Google Earth has to work with.

What version of Google Earth Should I use?

We recommend using the latest version of Google Earth: Beta Version 4. Although this version is labeled as "Beta" software, which typically means that all features are available but some bugs may remain in the program, we have found this version to be remarkably bug-free. We have also found that is is better at displaying our KML data file (the file you download that contains all the campus information), which uses the latest version of Google KML specification.Download the latest version of Google Earth

What are the System Requirements for Using Google Earth?

How do I find my System Information in Windows XP?

Checking CPU Speed and RAM
  1. Click the Start button at the lower-left side of your display.
  2. Click on Control Panel on the lower-right side of the Start Menu .
  3. Click on Performance and Maintenance in the lower-left side of the Control Panel window.
  4. Click on the System icon.
  5. In the System dialog that opens, you will see listed in the General tab under Computer a set of specifications for your computer, both the CPU (central processing unit) speed in GHz (gigahertz) or MHz (megahertz) and total RAM (random access memory) in GB (gigabytes) or MB (megabytes).
  6. The required CPU speed for Google Earth is 2.4+ GHz. For conversion purposes, 1024 MHz = 1 GHz, so this requirement is roughly equivalent to 2450 MHz. Check to see if your computer meets the requirement.
  7. The required total RAM for Google Earth is 512 MB. For conversion purposes, 1024 MB = 1 GB, so if you have more than 512 MB or more than 0.5 GB, you meet this requirement.

Checking Hard Disk Space

  1. Click the Start button at the lower-left side of your display.
  2. Click on My Computer on the upper-right side of the Start Menu .
  3. Click on the drive where you installed Google Earth (this is the C: drive by default).
  4. The Free Space will be listed in the Details display on the lower-left side of the My Computer window. For conversion purposes, 1024 MB = 1 GB and the required amount of free space for Google Earth is 2 GB, so if you have more than 2 GB or more than 2048 MB, you meet this requirement.

Checking Display Requirements

  1. Click the Start button at the lower-left side of your display.
  2. Click on Control Panel on the lower-right side of the Start Menu .
  3. Click on Appearance and Themes on the upper-left side of the Control Panel window.
  4. Click on the Display icon.
  5. Click on the Settings tab in the Display dialog.
  6. In the area under the Settings tab marked Screen resolution there is a slider that adjusts the resolution. The required resolution for Google Earth is 1280x1024. Move the slider until it is at this resolution or higher.
  7. In the area under the Settings tab marked Color quality there is a drop down dialog that adjusts the color settings of your display. Select Highest 32-bit from this drop down.
  8. Click the Apply button at the lower-right side of the Display dialog. Your screen may flicker to adjust to the new settings. If your screen can display at the new settings, you will see a dialog box asking you if you want to keep the new settings and counting down from 15. Click Yes to apply the new display settings. If you do not see this dialog, or your screen is blank, wait 15 seconds and you will be returned to your old display settings.
  9. Click on the Advanced button is the Display dialog.
  10. Click on the Adapter tab in the new dialog window.
  11. In the area under the Adapter tab marked Adapter Information there is a line marked Memory Size . The required amount of video memory for Google Earth is 32MB. Check to see if your video card meets or exceeds this requirement.

Checking Network Speed

  1. The required Network Speed for Google Earth is 768 Kbits/sec. This is the average speed for most Broadband DSL or Cable internet services in the United States.
  2. You can check your Network Speed using an online bandwidth test, such as the Speakeasy Speed Test (requires Flash). Such tests are not always accurate, but should give you a rough approximation of your Network Speed.

How do I find my System Information in Linux?

Because there are many different distributions and window systems for Linux, there is no single, definitive way to find System Information. If you are not sure how to find System Information on your Linux system, contact your System Administrator.
