Stereo Pairs with Google Earth

Stereo Pairs from Google Earth for Printing & Stereoscope Interpretation

– Open Google Earth and maximize the window on your screen.

– Tools menu > Options > check the box for Show Terrain.

– Tools menu > Options > set Elevation Exaggeration = 2. Adjust this as needed (1-3).

– Make sure there is no tilt to the view (Shift-click-drag mouse straight forward).

– The following 4 steps unclutter the display:

– View menu > turn off Status Bar.

– View menu > turn off Toolbar.

– View menu > uncheck Atmosphere.

– View menu > Show Navigation > Never.

– Zoom in to the location of interest and roughly center it in the window.

– With the view set, File > Save > Save image > Save a .jpg image as “Left_VE2″.

** Note: The free version of Google Earth only lets you save images in.jpg format at 72 DPI, which is the internet display resolution standard (very low resolution). Google Pro has higher resolution options for saved images.

– Without changing the amount of zoom, pan the map to the right a few inches (create the parallax offset).

– Save this image, this time as “Right_VE2″.

** Note: The amount you pan the image to the right will depend on zoom level (eye elevation), elevation exaggeration, and relief of the local landscape. You may need to tweak one or more of these to get it just right.

– Open you images in Photoshop and print. My example images opened at 18.9″ x 9.5″ at 72 DPI by default. Yours will differ depending on monitor size and other settings.

– In Photoshop, Image menu > Image size > change Resolution to 200. My example changed to 6.8 x 3.4″ at 200 DPI.

** Note: Other than changing the resolution this way, avoid adjusting the size of the image; you’ll only degrade the resolution unless you have mastered the image size/resolution/dpi game.

– Image menu > Canvas size > resize to whatever paper size you need (or what size your printer can handle).

– File > Print. Try to print in color. Scaling in the print setup may be necessary. Be consistent from one photo to the next.

– Figure out where you put that stereoscope…

** Note: If you want 3D anaglyphs (red/blue images used with 3D glasses) see website for freeware StereoPhotoMaker.
