Create interactive staff map on Sharepoint

Hi All,
After some advice on creating a map of the UK that shows all of the our sites to be used on our SharePoint intranet. Using SharePoint Designer 2013 . When you look at the map it would show the locations of our sites and if you clicked on one of them you would see the information about that site. E.g Engineers names and contact details email and phone with a picture if possible. Has anyone had experience in doing something like this and what tools did you use?
Thanks

It's clear what you want Google maps gives you options to do a lot like that with custom maps or you can create and image in HTML and set hyperlinks for each site
