I've successfully used QGIS to help me convert Census Bureau shape files into a custom map of state Senate and House districts. I'm hoping there is a way to save these maps as a map layer or geography that Tableau recognizes similar to a county or other substate geography for future use.
Is there a way to accomplish this? I'd like to not have to reinvent the wheel so to speak each time I go to create a viz.
I don't know if there is anyway you can save the polygon map in the tableau, but if you can use another offline map host engine to store the map data. The engine is geoserver, it can be used as a TMS engine in your local pc.
