Great Circle Mapper


I love the maps that Karl at Great Circle Mapper ( makes available. Now I’ve made it easier to embed them in a blog post on WordPress. Added bonus: It automatically includes the links back to Karl’s site per the notes in the FAQ page. Simply install the (very lightweight) plugin and you get a new shortcode to use on your site: [gcmap]. Parameters are available to control the look and feel of the maps as part of the shortcode.
