Geo Mark is a WordPress Plugin which will automatically locate Geo information in your WordPress posts using Yahoo Placemaker and YQL API’s.
Once the Geo location is located, it will add this information as custom fields to the post. The information stored in the custom field can be displayed anywhere in the post using the build in get_post_meta() function. The Plugin also exposes template functions which can be used to generate GEO Microformats based on the location information found in the post.
The Geo Mark Plugin also lets you to expose the location based information in RSS feeds. The Geo information stored in the custom field can be used to create Geo tags in the RSS feed. The Plugin supports the following Geo RSS formats.
- Simple (georss:point)
- GML (gml:pos)
- W3C (geo:lat)
Download
You can download the Plugin as a zip file from the official WordPress Plugin repository.
Installation
Extract the zip file and just drop the contents in the wp-content/plugins/ directory of your WordPress installation and then activate the Plugin from Plugins page.

The pot file is available with the Plugin. If you are willing to do translation for the Plugin, use the pot file to create the .po files for your language and let me know. I will add it to the Plugin after giving credit to you.

Great article, adding it to my bookmarks!
Awesome job !!! keep it up.
hi Sudar,
In my sidebar, I want to automatically log where I made the last post . Is this achievable with your plugin?
An example of how to use it for the millions who use wordpress but not PHP would be great.
thanks,
Peter
@Peter,
Right now it not possible out of the box. But this seems to be a valid usecase. I will add it to my todo list and will implement this feature when I get some free time.
Hello. Can I retroactively apply this to the posts that already exist on the blog? Or will it only apply to posts created after this is installed?
Right now you can apply it only to posts that are created after the Plugin is installed. It will also work if you edit the old posts after installing the Plugin.
This is definitely something I’m interested in using for one of my sites.
At the moment, I’ve previously manually added the lat/long as my own custom fields per post (I can handle any migration of that). For this plugin, does the user get to enter the lat/long if they choose, or is it something that’s detected by the user’s machine via WiFi, etc.? It wasn’t clear to me from the overview (sorry).
I like the GeoRSS feed feature, too, which I wanted to use for displaying posts on a Google Map using the existing site feed.
For what it’s worth, you can check out what I have now over at http://www.mauibyphoto.com – click on one of the photos on the home page and you’ll see what my posts look like. There currently is a Google Map Image (using their static image API) that shows the location of each post. If I could utilize this plugin for storing the location details, displaying the name via Yahoo’s API, and the GeoRSS feed, I could implement a shortcode for the static map image on my own and would be happy to send that code back to you if you’d like.
Also, I have another blog that’s a photography portfolio that references photos on Flickr that are geotagged. I’m already using the Flickr API to pull in EXIF data, so I could definitely see doing something with this, too, to show location and a map of where the photo was taken.
Great work here, and looking forward to your thoughts.

Kris,
This Plugin uses the Yahoo Geo Marker API (which analyzes the content) to get the Geo information.
