One of the things I’ve been doing with photography at my flickr.com site is adding the pictures I take to the map at flickr. This lets you know where the pictures were actually taken. However, it is a manual procedure and some pictures are taken on road trips and not a locations you can easily remember especially later that night or days later when you upload the pictures. So I’m going to try this device that you simply attach someone on your person and it constantly writes your GPS location to a log. You can then later (using software) take your pictures with their timestamps and match them to the GPS log and it’s timestamps and know exactly where the picture was taken. I’ll give it a try tomorrow and update here how it goes.
