If the appropriate checkboxes are selected in the Post submit box when saving the Post, the plugin reads the EXIF data of the Post’s Featured Image and adds Post Tags and a custom meta value “location” containing the serialized GPS location data of the image.
<ul>
<li>If the Post has no Featured Image, or if the Featured Image’s EXIF data is incomplete, then nothing happens.</li>
<li>The EXIF data is read directly from the image file, not from a database entry.</li>
<li>If standard values “GPSLongitude” and “GPSLatitude” are not available in the Featured Image’s EXIF data, the post will not be updated with the custom meta field. (A pre-existing value will not be deleted, if this happens.)</li>
<li>When saving Post Tags, the standard taxonomy <code>post_tag</code> is set. If you need to modify this, for example in the case of a custom taxonomy, then you can use the filter hook <code>update-post-with-exif-data/post_taxonomy</code> to change it.</li>
<li>If you want to see the custom meta value containing serialized GPS location data in the WordPress backend, you’ll need to parse the data and add this field yourself. A good solution for this is the “Advanced Custom Fields” plugin by Elliot Condon, with field type “Google Map”.</li>
<li>Developers: see the code for a WordPress action hook <code>update-post-with-exif-data/no-gps</code>, which fires in the event that there is no valid GPS data available in the Featured Image.</li>
</ul>
