Show Map of locations filtered by taxonomy categories

Hi
If Marcus still wonders if it would be a good move to add locations’ categories, I have tiny issue 😉

I’m trying to implement taxonomy categories I made to work with location map.

I’d love to have a possibility to use enhanced shortcode like:
[locations_map city="barcelona" taxonomy="tax" category="pubs"]

But anyway – we can make come code and show up the map:

global $EM_Event;
$EM_Event->output("#_LOCATIONMAP")

Now – how to add taxonomy and category to that code?

Do you have a clue guys? Thanks!
