Have a GPS and a digital camera?

Went for a walk to try out my new script.

Walkabout

Seems to work.

Here's my latest virtual tour:

Painted Desert Tour

There are probably too many pictures on the tour right now, it is a work in progress.

so how's it done?

The timestamps saved in photo Exif information can be used to match the photos with a GPS tracklog. When I'm out taking pictures I keep the GPS tracklog running. I take a picture of the clock on the GPS unit in order to synchonize the photo timestamps with the clock on the GPS unit. As far as equipment needed, you just need a GPS unit capable of saving and downloading tracklogs and a digital camera capable of saving Exif information. Most modern cameras do this automatically.

Then I download the photos and the tracklog (using free software) and run the photos and tracklogs through a perl script I wrote that pairs up the photos to trackpoints using the timestamps and saves the matching points to a waypoint file. The script will produce output for Google Earth, Google Maps, or ArcGIS.

For the Painted Desert tour I was able to mine old tracklog files and photos I'd taken in 2003-04.

The script requires a Garmin GPS, ActivePerl 5.8.x, DNRGarmin, and the ExifTool perl module to use. I wrote a help file that explains how to use it. If anyone is interested in trying it out, I can zip up the files and make them available later today.
