This plugin is intended for travel blogs, hiking blogs, where you want to show a map of a location you are writing about.
It’s really simple. It just adds an extra field in the WordPress admin editor, and if you enter GPS coordinates, it will add a map in the bottom of the post.
Acceptable types of GPS coordinate formats:
<ul>
<li>
N 45° 46.000 E 014° 12.000
</li>
<li>
S 45° 46′ 1″ W 014° 12′ 1″
</li>
<li>
+46° 22′ 38.11″, -96° 9′ 55.90″
</li>
<li>
N 45.766667 E 014.200000
</li>
<li>
-45.766667,014.200000
</li>
</ul>
