I love the maps that Karl at Great Circle Mapper (gcmap.com) 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.
More details available on the <a href="http://blog.wandr.me/plugins/great-circle-mapper/" rel="nofollow ugc">plugin homepage</a>.

This plugin helps you create a simple travel map to display on your blog. The map is using the Google Geocharts API. Markers are placed on all locations found in your posts (inside a custom field of your choice). Clicking a marker links to the post associated with that specific location. Hovering over a marker opens a popup with the title and a thumbnail (if the post at that location has one).
I built the plugin to create a map of the places I have visited and you can <a href="http://thomashoefter.com/" rel="nofollow ugc">see it in action</a> on my personal site.
<h4>Features:</h4>
<ul>
<li>Set a location for each of your posts or pages and display them in a map!</li>
<li>Display the travel map in any post or page of your choice with a shortcode.</li>
<li>Clicking a marker will bring you to its associated post.</li>
<li>Hovering over a marker shows the post title and thumbnail image.</li>
<li>Works with responsive themes: The map can automatically take the size of the browser/container it is in.</li>
<li>A settings page to change the map colors and marker size</li>
</ul>
Limitations: As the name says this is a simple plugin I built mostly to solve a problem for myself. It does exactly what it says above but, at least for now, not much more. There is no support for other map types and locations can only be added based on a custom field in your posts.
Please have a look at <a href="http://wpscoop.com/simple-wordpress-travel-map-plugin" rel="nofollow ugc">this post for more information as well as details on how to install and use my simple travel map plugin</a>. In the post I have also written about some good alternatives to this plugin for slightly different purposes.
