A Brief Introduction to GPS Photo Linking

In the land of the keitai (Mobile phone in Japanese) we have a carrier, AU, which sells GPS enabled mobiles to everyday consumers for use in Location Based Services such as city guides/navigation systems. The keitai I use is by Casio ( in Japanese), and it's a 2Megapixel GPS enabled unit. After taking a photo there is an option to grab your coordinates, and this information is stored in the JPEG as EXIF metadata. Now you can attach this to an email and shoot it off to a server for some fun.

A project called Tokyo Picturesque accomplishes this, and similar to the GPS Photo Linking project described in this article, maps these photos to a 2D map.

    Thanks for link to that site. Great concept and really nice interface.

    Phones really could be great for this. Camera, GPS, and ability to upload to web all on one small device, and you can talk to people on it to.

    It is neat that you could have a "where I have been" section of yoru website that works kind of like a visual blog. Whenever you are out taking photos it automatically gets posted to your 'Visual Blog"

      The back end is done mainly with ColdFusion with a pinch of Java by a kewl coder ,and crazy friend Kentaro here in Tokyo. The Flash portion is done (or I should say reDone ;) ) by a guy named Tozaki from Karate Systems. He's into Rich Internet Applications.

      I like the ease of moblogging, and the phone gets the GPS coordinates in 5 to 10 seconds. This is very acceptable, but have to tell whoever I'm with to 'hold on a sec while I get our position ...'. I haven't checked how the GPS coordinates work with short videos taken with the cell, but I would imagine it would be an external link. Currently when attaching GPS info to the photo, and preparing to email ... the phone will ask me if I want to add an URL. This URL points to a mapquest type of site of Tokyo done by Toyota. Maybe the video will include this URL.

      Other ideas of the Visual Blog are to sort by date, time, proximity, and color. A professor from German who currently resides here has been 'moblogging' w/ GPS for about two years now. He's got a great resource of personal data that he can check by date, time, and proximity. And did a collage by color too. I keep urging him to share his personal experiments, but I think he's a little shy. Hopefully soon.

      If you ever visit Tokyo please let me know, and we'll get you a phone to play around with!

      Take care,
