On a recent road trip around Iceland, my friends (PHP developers Andrei and Helgi) and I decided to make a travel site. We brought our cameras, GPS, and Flips, and we used PHP to:
* Aggregate our experience in the form of photos (Flickr), tweets (Twitter), and videos (Vimeo).
* Geotag all of these assets, so we'd remember precisely where we were.
* Create a map that marks our path each day and plots our photos, tweets, and videos.
We made most of this while taking in scenic views and experiencing all Iceland has to offer, and we learned a lot about geotagging, GPSes, time zones, and maps along the way. This talks shows you how to do the same, but you'll have to buy your own flight.
