This type offers three ways to define the location to base the map on: Postcode, County, or lat lon. I don't know if County is set up yet. It works off of another Area api that I cannot remember if I fully migrated to the new site from the experience site.
POI by latitude and longitude
Thrown together during the most recent CFP frenzy to display pois. But not limited to poi content, can also display routes. Uses lat lon to define centre point.
Map embed by proximity
This one I can't recall how it works, or what it is for.
