I went for a short photowalk to photograph a freezing rain event that occurred overnight January 17-18, 2011 in the Washington, D.C. metropolitan region. The diptych (shown above) was created using Diptic app.

As promised in my last post, Photowalking Hollin Hills, here are step-by-step instructions describing the workflow for creating a KMZ file that features a GPS track and gallery of geotagged photos, suitable for display in Google Earth.

1. Save- and export a track (GPX file) from a GPS device, such as MotionX GPS for Apple iPhone.
2. Create a gallery of geotagged photos using Picasa for Windows.
3. From the menu bar in Picasa, select Tools/Geotag/Export to Google Earth File; save the resulting KMZ file to a known location. (Editor's Note: This option is not available in Picasa 3.8.7.361 for Mac OS X.)
4. Open the KMZ file of geotagged photos in Google Earth.
5. Open the GPX file (GPS track) in Google Earth; drag the GPX file into the KMZ folder of geotagged photos.
6. Select the KMZ folder (containing both the GPX track and geotagged photos). From the menu bar in Google Earth, select Save/Save Place As...; create a name for the new KMZ file and save to a known location.

A sample KMZ file (Picasa_23Feb2011.kmz) is shown above.
