Google Maps Plugin for Buddypress Activity Stream

Hi Guys,
I have a Buddypress installation.
Here, people should be able to post a location to somebody elses activity stream.
I also would like to show it in a map in the activity stream. But it is neccessary, that users don't have to type the adress but using GPS and / or metadata of a picture they have posted to somebody elses activity stream.
And at least, I need the option to find the latest location of every user in one map.
Would you please be so kind to tell me, if this is possible with the Google Maps plugin?

Thank you, Denise
