I have been diving into the Google Maps API for the last couple of days. After finding the nice Google map module for WordPress I started looking for a way of geocoding the photos that I took while travelling around the world on a bicycle.

One solution is to find the geocode for a photo by manually positioning it on a map, this would be very time consuming and tedious. The other solution is to use the time-stamp of the photograph (almost all digital camera write this into the EXIF data) and a track-log( which is a log kept by a GPS unit about where it was at what time) to calculate where the photo was take.

The good news is that most of my photos are timestamped, the bad news is that I didn’t have a GPS so I don’t have a track-log of where I went. But I did always draw on a map the route that I was taking and I kept a daily journal of the places I visited. So I did a search of the web for a program which would allow me to draw a track-log by hand then I could feed my photos and this track-log into some freely available photo-llinking program which would time-stamp the photos with the geocode.

I was amazed at the amount GPS stuff that is going on, there seems to be a revolution going on in that field, nevertheless I couldn’t find exactly what I was looking for so I decided to write my own Google Map application. It has been a steep learning curve but I am slowly getting there, here is a preliminary work-in-progress application as I start to build it up.
