OK, so I've been spending sometime recently trying to work out the easiest way to turn my basic blog into a geoblog...So what's the difference?  Each post should contain a latitude and longditude tag.  There are a number of diffrent methods you can use to get into geobloging:
1. Create a public map on Google Maps, put in a pin for every post.  This is great if you just want to keep notes on locations but doesn't allow timelines
2. Use a service like Flikr to post photos and link them to locations on google maps.  This is an extension to above and as Flikr allows you to browse by date you get the timeline.  It is hard however if you want to post articles without photos or for people to find your articles.
3. Use a standard bloging tool and create manual links to a google map, this works well, but doesn't actually geo tag your articles
4. Use Google Maps to generate links to your articles and thus generate the geo tags
5. Find some bloging software that has all this built in

As I use Blogware I didn't go down option 5, however it looks like wordpress is working on implementing geo tags.  Blogware, like many comercial bloging platforms doesn't give you the facility to insert your own tags into posts and so I had to find another method to get the geo data linked to my posts.  I also had the issue of trying to find the location with ease as I don't carry a GPS around with me.  The solution I decided to try and implement was to harness Google Maps to create the location information and create my basic post.  I then wanted the post to link back to the Google Map.

At the moment I haven't quite managed all of this, however I am able to generate rss feeds from a Google Map which can be read by my bloging software, this then creates links to my blog articles.  I then create a manual link back to the Google Map pin.  Here's how it's done...

1. Get yourself a Google account and create a map and put some pins on it
2. In the top right of your My Map there is a link to View in Google Earth, copy this link
3. Go to http://pipes.yahoo.com/ouseful/mymapsblog and paste in your link and run the pipe, your pins will be displayed (on a Yahoo map)
4. Hit more options and choose RSS and copy the feed link
5. Go to your bloging software and create a RSS import feed and paste the link you just obtained - this will now bring all of your map pins into your blog
6. In your map pins by using url:myblog.com/articleid this will turn the import feed article titles into links, by using date:1 April 2008 you can encode a date
7. To get your articles linking back to each map pin, on your Google My Map, click the pin you want to link to and create the view you want of the map, then hit the Link to this page button and copy the link, insert this link somewhere in your article.
8. Hurrah, people can now find your blog articles by location or when reading your article find it's location.  Magic!
