Can i ask what kind of plugins are you looking for? Did you try Map Box? There are few formats which really help in changing the granularity of the maps. Check it out. Also i will try to post the link here, One of the Zen Masters have a building specific maps on their blogs, but i am not sure if you that is what you are looking for.
Thanks for replying Amerendra,
I am looking at doing Street Level Analysis ie I am looking at point specific addresses on a map using tableau.
Does Tableau has any such feature ? or is their any way to accomplish this using Tableau ?
Using map box you can do something similar. But the exact address mapping i am not sure if we can do it.
Thanks for your help. Mapbox almost worked. I intend to try and see if it solves my purpose. Thanks again.
