Image location-stamping software...

Recommended Posts

A bit back we stumbled across a piece of software on the 'net that would take the track log from a GPS, a directory full of digital camera photos, and annotate the photos with the GPS coordinates where they were (probably) taken, based on the timestamps in the photos and the GPS logs. We thought this was pretty durned nifty.

 

... and then we found out that it was more than $200!

 

So Jay spent an afternoon whipping up a perl script to accomplish the same thing. It isn't nearly as pretty as the other software, but seems to work, so far. We thought we'd share a preliminary version of the script, on the off chance that it would be useful to someone (and the very off chance that someone wanted to help improve it).

 

Basically, you just feed it a list of your track logs (saved from expertgps in .gpx format), a list of your images, and it compares timestamps and adds a .txt (or whatever extension you specify) file alongside the image containing the (probable) coordinates at which the image was taken.

 

It's in perl, and I'd be really suprised if you could get it to work on anything but a *nix box, right now. There's no inherent reason it -couldn't- work on windows, if it has the right modules, but that's completely and totally untested.

 

You need to have the XML:icon_biggrin.gifOM module (and the XML libraries it needs) installed to run this (consult www.cpan.org). "perldoc locstamp" will give usage instructions.

Disclaimer: It's been lightly tested so far, but that's it. If it crashes and burns, destroys your computer, and makes you grow three heads and feathers, don't complain to me (though we'd appreciate a bug report icon_smile.gif

 

Enjoy.
