Geocoding Your Photos

Friday, August 1st, 2008

Hi Everyone,

For those interested in Geocoding their images, I thought I’d put together some information which may help.

I like to geocode my images with coordinates for a couple of reasons:

  • I know exactly where I took the shot if I ever want to return; and
  • I can add them to map applications like Google Maps as waypoints/points of interest, etc.

How to do it ?

1) As long as you have a GPS device capable of recording your track it’s pretty easy from here.

2) I turn my GPS on before I start shooting and have it recording my track until I finish.   So long as your able to create a GPX file afterwards, you can go to the next step.

3) Google have developed a geocoding tool which actually writes to your cameras raw files (*.CR2). I have not trialed a better app than this one – most only write to JPGs.   Google’s product is free to download and use (as all great Google products are !!).   You can download GPicSync here

4) If you do use the tool, just be mindful of time difference, i.e. GPS devices usually record tracks in UTC times, whereas your camera will probably set to your local time.  The GPicSync application can be set to adjust for this in the configuration.

Hope this helps for those who are interested, enjoy.

Jared
