How to create a Gmap view that can be filtered? I have a taxonomy vocabulary that has a multiple terms.

I can create a view that shows the location of all terms in a map, but I want to filter these locations by term. I mean the user first chooses which term and then the map only shows the location of this specific term.

I don't know how to set up filter criteria correctly to achieve this, any suggestions?
Have a look at the IP Geolocation Views &amp; Maps module. Partial quote from its project page:

Despite what the name may suggest, IP Geolocation Views &amp; Maps (IPGV&amp;M) is first and foremost a mapping engine.
The module makes it very easy to create Views-based mapping solutions using the map renderer of your choice (Google, OpenLayers or Leaflet) with any location storage module of your choice, e.g.:

Get Locations,
Geofield,
Geolocation Field
Location.




This allows you to bring together modules and feature sets that without IPGV&amp;M you would not be able to combine.
Like beautiful animated marker clustering on Google or Bing or Mapbox ... any of various map providers.
But more importantly IPGV&amp;M adds some features you won't find as conveniently packaged elsewhere.
These include marker differentiation based on field values or ranges (2nd screenshot) with or without font icons, various centering options, super-imposing the current visitor's location, allowing multiple content types to be displayed on the same map, full screen button and mini-map inset (bottom screenshot), polygon support (Geofield), marker tags and tool tips and cross-highlighting of associated content on the page when markers are hovered (and vice versa).


Head over to its (impressive) project page for even more information about it (it would be way too long to include a quote of it all here). That project page also includes various screenshots.
Specific to the &quot;filter&quot; part of your question, here is a quote (also from the project page):

For those using the Commerce module a ready-to-use Order Locations map is provided (3rd screenshot). For each order placed at your store it outputs a marker on the map with its location details retrieved by IPGV&amp;M. The view comes with filters to zoom in on country, time frame and order status. Each order location marker, when clicked, reveals in a text balloon details of the order, e.g number, date placed and order status as well as street address.

Note: Uploading custom markers should be possible also, similar to what you can see in the screenprint in the feature request about Custom markers.
PS: I'm assuming this question is about D7 ...
