Derick Rethans has a new post today with a bit of code showing how to combine Flickr and OpenStreetMap and make a mapping tool that plots out the location information for the Flickr images.
I like taking pictures, and I usually take a GPS so that I can place them on a map on my Flickr page. On my last excursion however, the battery of my GPS had died, so I did not have location information available to store in my pictures' EXIF headers. Flickr can use the EXIF headers to then show the images on the map. Because I did not have the location information to automatically place my pictures on the map, I wanted to do that by hand.
His script (as used by a local Squid proxy) supports two different versions of the mapping - one for Yahoo! Maps and the other for OpenStreetMaps'. You can see the end result here - a set of Flickr images with a map in the background.
