Any thoughts on how to implement a geolocation (map) in Domoticz?

Using the carwings API I request the location of my Nissan Leaf. The result is a set of coordinates or an URL
http://www.openstreetmap.org/search?que ... 2666666667

Is it possible to include a small map or as an alternative to convert the URL to a city name?
