I’m a big fan of the WP Geo plugin, but I want more.

My biggest complaint is that I want to insert coordinates using Google Maps or MultiMap URLs, rather than insert them in the modified story editor. So I wrote a bit of code that reads through the URLs in a post, finds the “maps.google” or “multimap.com” URLs, fishes the latitude and longitude out of them, and adds some geocoding tags to the body of the post.

Take a look at how it works with these posts in my archive…

You should see one or more blocks of links like the following (from my Osceola Weekend post):

geolocation: geo:lat=44.006336, geo:lon=-71.547260, geotagged, geolocation:44.006336,-71.547260 geobloggers

Go ahead and click the “geobloggers” link. I could have added these links using the old Geo plugin, but I still would have had to insert the coordinates separately. Actually, that brings up a good point: my code also inserts post metadata in the same format the Geo plugin uses, so I can take advantage of all the good functions it has, like the one that inserts the “<meta name=“ICBM” content=“44.006336, -71.547260” />” tag in the header of this post (caveat: I had to disable the add_action code in Geo that feeds the postmeta table, as it was conflicting my code).

I’m releasing this now, to start some public discussion, but please recognize that it’s a very early beta.

Download: bsuite_geocode.zip
Install: place unzipped “bsuite_geocode.php” file in your wp-content/plugins folder and activate it via the WP control panel. See the WordPress Codex for more detail.
Use: write posts as usual, adding links to Google Maps or MultiMap as appropriate. Links to those sites that have latitude and longitude components will be used to geocode the post.

Example of a working URL:

http://maps.google.com/maps?ll=19.355507,-155.072365&spn=.191780,.318003&t=k&hl=en

Example of a URL that won’t work (note how there’s no “ll=”):

http://maps.google.com/maps?q=decker+canyon+rd,+malibu+california&spn=0.019857,0.039750&hl=en

I’ve got a lot of features and uses in mind, so consider this only a start. Please post bugs and suggestions in the comments.

Also, see these previous posts on geolocating the news or geolocating everything or just search the archives to understand why I’m so excited about things like this.

It would reasonably appear that here in the US, there’s only one map site: good ol’ Google. But until Google adds maps for countries other than the US, Canada, and UK, the rest of the world will have to look elsewhere. Enter the UK competitor: Multimap.com has been serving the world outside the bubble since 1996. From their self description:

Key features include street-level maps of the United Kingdom, Europe, and the US; road maps of the world; door-to-door travel directions; aerial photographs; and local information.

In short, it’s probably the best place to point any random set of coordinates. Example: my story about the Chernobyl tour should probably have included this street map of the region. (Yes, Google will now give me a low resolution satellite photo of the reactor, but photos and maps offer different value for different uses.)

My only complaint is that the service lacks the AJAX features that make Google Maps so great. But that might be changing. A post at The Map Room tells of a new feature for UK regions: a map overlay follows the mouse on aerial photos. Take a look at this example. Nice trick, eh?
