We like to link the places of our sensors in a map (like Google Maps).
Re maps, do you mean have a map as a background and then put your point views on top of it? This is already possible by uploading a map image. You can even link to other views in a server-side script if you want a drill-down sort of thing.
Thank you for the information.
About mapping: I mean that how we can show the places of the sensors in a Google Maps or other Web 2.0/Map application (like openstreetmap). That view would be public.
That would depend more on the mapping API than on Mango. Mango doesn't have any explicit fields for storing a point's geolocation information, so i'm not sure where you would be pulling that from. But, that's what something like Google maps would need.
