I've seen people do similar things before. You can do this using background images:
Then, to plot things on the image:
Hope this helps!

If you have a DXF or similar format (Autocad) of the plan, it can be converted to ESRI SHP. Then you import that into Tableau (shapetotab, Alteryx Script, Mary's R method, ET Wizards for ESRI etc).
You won't even need a projection, unless you are wanting it to be geo-located.
If you want a simple plot, you could use ImageJ and convert your picture to text. This gives a txt file which you can use the Tableau Excel add-in to re-shape the data. Example here.
The example you forwarded contains a floor plan is almost exactly what I am imaging.
I will see if I can outline boundaries as to shade an entire room, instead of a single point, but even so that may just do the trick.
This is awesome to know as well, Allan. Hadn't thought about an Autocad file! More advanced than I pictured but very useful.
This should all do the trick as I don't need geolocation.
Thanks a ton!
Could you show a step-by-step on how to do this?
I saw this and thought you might be interested. In this posting, we were looking to find polygons and convert them into tableau.
