Twitter messages on a map
Posted By erik on June 9th, 2010
One of my hobby projects is building a tourist map of Tokyo. I started out with displaying a RSS feed from Google Maps on my own hand-drawn map of Tokyo. Even though the Google Maps API now allows custom coloring of your map, I still think google’s maps are overpopulated with information and are visually not very inspiring.
Having the system in place for placing geo data on my own map, I realized it should be just as easy to display twitter messages, as long as they include geo data:

Retrieving twitter messages with geo data from http://search.twitter.com/ starts with including a geo location in your search parameters (in this case ‘tokyo’). Still, many twitter messages include geo data that only includes a town and no latitude/longitude information.
For this map, I retrieve 60 messages that were twittered in Tokyo, and then filter out all the messages that actually have a latitude/longitude. When using a map of an entire country you’d get a lot more twitter results so that’s going to be the next step in this project!

Erik, cool finding your stuff.
Im trying to achieve something similar for a project I have currently. I was wondering how do you achieve having twitter on your map? Also, have you done geo photo map? any help will be great.
thanks!

Hi Guillermo,
You can query the twitter API for messages that fall within a certain geo area. In this case I used a point in Tokyo and fetched all twitter messages from within that area.
The next thing is to translate the included geodata to your custom map.
You could do exactly the same with photos, as long as they include geodata!
