GPS tagging photos on Flickr has been done for a long time, but I had not seen it on regular blogs yet. Why not? You could do a lot of fun with that! At least I hadn't heard any noise about it so I thought it hadn't really taken off. But of course some clever people had started working on this long ago and things are well on the way.

The first thoughts around this I got from reading an article on O'Reilly radar about Google supporting GeoRSS. That led me to the GeoRSS homepage which links straight to geotagthings.com. In geotagthings (still in beta) you can subscribe to a feed that's an aggregation of many geotagged feeds that are limited to be within a certain area of your choice. I think it would be really fun to see what other bloggers in the block are saying and what pictures they are posting.

Then of course there's the question of how to easily add geotags to all blog posts. It should of course happen automatically if possible, but good support for adding it manually should be built into all blogging software. There should be the possibility to save some default locations where you do most posts from and a row with free editing, just to enter latitude and longitude.

There's a newly started GNOME project called GeoClue, which is about making a DBus service for geographic information. They have a great list on the homepage with suggestions of how this information could be used and I really hope this to takes off. The more this is integrated into the desktop the better.

One of many cool things mentioned on the GeoClue page is Placeopedia. Placeopedia is an effort to connect Wikipedia articles with the location they are talking about. This is exactly what I want to have in my Neo1973 when I'm out traveling somewhere. "Is there something interesting around here?" - One look on the map and I can click and read the article about it.

Of course some clever minds at Google have also been looking at this stuff. There's been some rumors that maybe Google was making a phone, but of course they were not going build any hardware. The proof for this is this patent for quicker search results when using a mobile device was dug up by Mad4MobilePhones. It shows that Google was, as usually, looking for a way to get better and faster search results. Jacqui Cheng at Ars Technica took a closer look on this new mobile search and really liked it. The last piece of the puzzle is how to add the positioning automatically. (Google's mobile search currently needs you to enter your current Zip code to tell where you are.)

GPS receivers are getting built into more and more things and now we have to make it possible to get the geographic information to all programs that can make use of it.
