Layers in Sidebar
•Use the Layer feature in Google only when necessary.
Each layer added to Google Earth will add rendering time

location was last taken.

Tips for Projects
• Have students design a storyboard prior to
beginning their project. The storyboard should
contain the locations they are going to select, and
the images, sounds or video, they will be adding
to the location.
• Keep all images in a single folder, keep image
names as short as possible.
• Make sure images are resized to less than 3” for a
better fit and reduce the resolution. 72 dpi is
perfect for web viewing.
Adding Place Marks
• Place Marks are like pushpins which help identify a specific
• Key the location address in the “what you are looking for”
text box and click the magnifying glass.
• You can use the navigation controls to zoom in, out or
• Click on the add placemark icon to add a placemark.
• You can change the icon for the placemark by clicking on
the icon button in the dialogue box.
• You can add text information to this placemark by keying
the information in the description area.
• This is also the location you will add additional multimedia.
Adding an image to the placemark
• You can add an image to a placemark. Google earth supports the
following: JPG,BMP,GIF, TIFF, TGA, and PNG formats.
• The most common issue when inserting and image overlay is the size of
the image. It is important to keep this in mind when designing your project
or edit graphics in a graphics editor prior to adding to the project. Larger
images can also be memory intensive. Images less than 3” in size and
saved at 72dpi is prefect.
• All objects added into the placemark, must be added using hypertext
markup language (HTML). I have prepared a cheat sheet to assist you with
• In the preplanning we saved the images in a folder, and gave them a short
name. To insert the image in the placemark you will need to know the
location path to the image. To get this path, you will right click on the
image and go to properties. Highlight this path, right click and choose
• You will need to start the line by keying <img src=“ paste path add\name
Geo Tagging in Picasa
• Picasa is another program owned by Google. Picasa is a graphics organizer which will
gather all graphics located on your computer and put them into one location.
• To “tag” a graphic in Picasa, select the photos you want to use, then click on Tools in the
Menu bar, then select, Geotag, Geotag with Google Earth. This will bring the photos
into Google Earth.
• Navigate to the location you want to place the photo, make sure the cross hair is over
the location you want the photo to appear.
• Click on the Geotag button, then done. The photo will be placed on the map in Google
Earth, once it appears, the item can be edited to appear as a place mark by right
clicking on going to properties.
“Geotagging” in Google Video
• If you create a video and save it to Google Video’s it can be
Geotagged for use on Google Earth.
• Upload the video to Google Video. Once the video has been
uploaded, click on the Embed Video link, a drop down box
with coding will appear. Copy this coding and paste it into
your properties area of the place mark in Google Earth.
This will embed the video into the place mark.
• Graphic Overlays can be in one of the
• BMP, GIF, JPG or TIFF
• The graphic overlay lays directly over the map

extension format must be reopened in Google

have the project selected, a check mark in all
boxes, then click File, Save, in “My Places”.
