If you are in a hurry, you can import the photos first and locate the GPX log file and the photos folder later. Now you don't have to carry out the GPS data merge at this point. When you get back to the computer you need to launch the LoadMytracks™ program described here to read and convert the log file and then launch the GPSPhotoLinker™ program to merge the GPS data with the camera files before importing them into Lightroom. This tiny Sony™ device can record the GPS coordinates of wherever the unit is, once every 15 seconds and save the GPS time-stamped waypoints as part of a log. The following steps show how I was able to import the GPX data from a Sony GPSCS1KA unit (see Figure 4.82) and merge the data with the camera captured images. In fact, it will only display the GPS field in the EXIF Metadata panel if GPS metadata is actually present in the catalog image files. Lightroom does not have any mechanism that will allow you to import or edit GPS metadata.

OK, now that I have shown you how GPS metadata can be useful, let's see how you can capture and embed GPS metadata in a series of photos. In this example I tilted the view to a ground-level view of the site where Ian took his photograph. If you happen to have the Google Earth program installed on your computer, you can also copy and paste the GPS coordinates and use the more extensive navigation tools to explore the scene where the photograph was taken.By the way, you can see more of Ian's photographs taken around the Falklands and Antarctica on his Computer Darkroom Web site. In the following steps, I have used a set of images with embedded GPS metadata, kindly provided by Ian Lyons to demonstrate how Lightroom can use such metadata to link to Google Maps.
LOADMYTRACKS SOFTWARE
Post-processing software synchronizes data captured by the device with the corresponding images. For example, according to John Nack's blog, Jobo AG™ has announced photoGPS, a $149 device that sits in the hot shoe (i.e., the mounting point for a flash) of a digital SLR. This is not as difficult as you might imagine, since there are now several GPS devices capable of capturing the GPS coordinates at the time of capture and then synchronizing the GPS data with your capture images via post-processing software. But in order to pull off this trick you will need to find a way to embed GPS metadata in your image capture files. If you have GPS metadata embedded in an image file, Lightroom will let you link directly to Google Maps and locate exactly where that photograph had been taken.

It is full of lots of interesting background information on what is going on at Adobe, as well as offering off-topic posts such as links to interesting photography Web sites. John Nack is product manager for Photoshop and Bridge and writes a blog titled "John Nack on Adobe" ( /jnack ).
