Add geocoding and Google maps to your WordPress blog
Robert Harm has written a tutorial how to show you how you can use your self-hosted WordPress installation together with the WP Geo plugin in order to dynamically display your geo-tagged posts or pages on the Wikitude World Browser.
Since the 3.2 release of WP Geo it is possible to easily add new marker icons via a filter, either in your theme’s functions.php file or as a plugin.
I would suggest that if you are creating a marker icon specifically for your theme you add it your theme’s functions.php file. However, it is possible to create a set of markers packaged in a single plugin – ideal if you want to share your icons by releasing them on the WordPress plugin repository. If you do this please tag it as ‘wp-geo’ to make it easier to find in the plugin repository.
Recently, someone left a comment on how to create a mashup page with a map of all your posts. It is something I know a lot of people ask how to do so I have written a ‘how to’ create a map of all posts template tutorial.
