OS OpenSpace Maps


A plugin to display UK Ordnance Survey OpenSpace maps with markers and tracks.

This plugin works using the [osmap] shortcode anywhere in your post, page or custom post type content. It allows maps with markers and gpx or kml files to be shown. Examples are available at and my blog.

The following parameters can be passed:

  • height="xxx" sets the height of the map div
  • width="xxx" sets the width of the map div
  • colour="red" or colour="#ff0000" (color is also acceptable) sets the colour of the track shown from a file.
  • gpx="" specifies a gpx file to be displayed
  • kml="" specifies a kml file to be displayed
  • markers="NY1234512345;Marker 1|54.454198,-3.211527;Marker 2" a list of positions and labels separated by | with a ; between the position and label. Positions can be 6, 8 or 10 figure grid references or decimal lat long.

To upload a kml or gpx file just use the WordPress media uploader and then copy the address of the uploaded file into the shortcode.


  • [osmap height="300" width="300" color="yellow" gpx=""] displays a 300px by 300px window containing a yellow track from the file specified.

  • [osmap markers="NY2000008000;Wasdale"]shows a default size and zoom window with a marker placed and the popup text “Wasdale”


  • A map embedded in a WordPress post
  • The settings page


  1. Go to the Plugins page in the admin area, search for openspace navigate to the plugin page and click install.
  2. Or download and extract into the /wp-content/plugins/ directory. This will create a subfolder called os-openspace-maps containing the plugin files.
  3. Activate OS OpenSpace Maps through the ‘Plugins’ menu in WordPress
  4. Before the plugin will work you need to add your API key to the settings page on the dashboard.
  5. If you are running WordPress Multisite you (or your network administrator) will have to add KML and GPX files to the allowed file types under ‘Network Settings’.


Where can I get support?

In the comments section at the plugin page

Where is the rest of the FAQ?

This will be extended in due course.

Planned for the future
  • Multiple kml and gpx files
  • A Shortcode Generator


Worked fine after a couple of minor tweaks

Initially I tried this and couldn’t get the maps to display at all. After picking up a few clues on the OS Openmaps forums, I made a couple of simple tweaks to the code in the plugins folder and fixed it. Apparently, if your wordpress site is https – something that’s becoming more popular – then you’ll probably need to make these tweaks. I have written the instructions in the Support section.
