Features of Travelers’ Map

• Geolocalize your posts, pages or custom post types on a map and choose the marker image. A search module is available to quickly locate the desired location.
• Add your own images to customize your markers.
• Insert a dynamic map that displays your articles using a simple shortcode. Choose the dimensions of your map.
• Filter the posts you want to display on the map by their type, categories and tags.
• Markers clustering is automatic when marker density is too high, to prevent them from overlapping.
• Customize the appearance of your maps with OpenStreetMap tile providers. By default, the plugin uses CARTO’s free and open “Voyager” map tiles.
• Customize the popup style and content for your markers. You can also disable the plugin’s CSS if you want to design your own popups.
• Travelers’ Map is compatible with the new Gutenberg editor and the classic editor.
• This plugin does not add any tables into your database.

The geolocation data of your posts are saved as meta-data and are not deleted if Travelers’ Map is disabled or deleted. However, if you want to uninstall Travelers’ Map permanently, an option is available to clean your database of any data added by the plugin.

* Added shortcode parameters “tileurl”, “subdomains” and “attribution” to override global plugin settings. This option is advised for advanced users only.
