Just Google introduced +Snippets for the Google+ to share easily the web-pages with a snips before submit. Today Google announced the addtion of Google Maps to this service which allow user have the snip of map then share it on Google+.
Important part to understand is that this is an integration of Google Maps with Google+. When user is on a place in the Google Maps and try to share the link via share box in the Google+ bar the snip and the map of the place on which user is currently will be shared. The preview of map will come-up as snippets over the box. She the image below which make-up what I say above.
While this intoduction help directly sharing the maps over Google+ with various things like of places, the directions and the search for the places and spots. Previously Google Books, Google Offers and Product Search had +Snippets now Google Maps also included and Google is trying to get more of their product to have it.
