Any of the maps included under "View the
Maps" on the Maps Home Page may be imported
into Google Earth as a layer. To do so requires first saving the
map file to a location on your computer where the map will not be
moved later, such as in the "My Documents" or "My
Pictures" folder on a Windows system.
Then follow the steps below:
1) Start Google Earth (GE)
2) Move to the Big Horn Mountains of north-central Wyoming
3) In your GE "My Places" folder, highlight the folder
(or sub-folder) into which you wish to place the map
4) Click on the word "Add" in the menu bar
5) Click on "Image Overlay" in the Add menu
6) The "New Image Overlay" box appears
7) Add a title such as "Cloud Peak Wilderness"
8) Click on the "Browse" button
9) Navigate your system to the map file you saved earlier
10) Click on the "Location" tab in the "New Image
11) Under that tab, copy and paste (or type) the
12) Click the "Okay" button at the
bottom of the box.
The map should now appear as a
three-dimensional overlay in Google Earth. Inevitably, some
quality and resolution is lost in the maps as they appear in
Google Earth. However, you can find named locations such as lakes
and trailheads. And you can add paths and pushpins to plan routes
into the wilderness.
As with most any map, some precision will need
adjustment if you turn off the layer and hover closer to the
satellite imagery of Google Earth.
