Viewing your posts as a route plotted on a Google map is simple with this plugin. Just add the shortcode [logmytripmap] to a page to see the map.
Your posts are plotted on a Google map as points on a route in date order. Just create a page for your map, then add the shortcode [logmytripmap] anywhere in the page to see your map appear. Clicking on a point icon can show a picture taken at that location if one is attached to a post. A small Google map is displayed on the "Edit Post" screen to allow users to geotag their posts.
Hovering over the address when viewing individual posts reveals a map of the post location. See http://www.LogMyTrip.co.uk for more info.
