To embed a map in another web page, simply use an IFRAME, like this:

 <iframe src=url>(non-iframe text)</iframe>

where url is a standard map linking URL - see The Map URL API. For example:

 <iframe src=""></iframe>

Typically your CSS will set the width and height of the IFRAME, though you can also do this directly:

 <iframe src="" style="width: 400px; height: 400px;"></iframe>

The presentation is slightly different from the full page for the same URL in that only the map is displayed without any ancillary information, titling, branding etc. There is a small control in the corner offering a menu including a link to the main map. (note: the map determines its presence within an iframe using a Javascript test). In the future, on small touch screen devices any touch on the map will probably just jump to the corresponding map page for more detailed presentation, so it just acts as a link.

We suggest not using the bounding box or ref form of URL for embedding a map relevant to an institution. By using the simple name of the institution or its code, then the map will

  • adjust if the institution moves (using  a bounding box or building reference leaves it showing the old geographical location)
  • centre on the institution concerned 
  • show a marker for just the institution concerned, not all of its neighbbours

Note that if your page is served using HTTPS, you will also need to use https to retrieve the map, otherwise users will receive messages warning about mixed and unprotected content on the page:

 <iframe src=""></iframe>
