Picasa is now integrated with Google Maps and Picasa mobile is also available. I used the new feature to map a recent Yellowtail outing around the Coronado Islands fishing grounds. The feature is easy to use and fun, but dragging-and-dropping photos onto the map is a best-guess positioning exercise.
