Creating Tableau Polygons from ArcGIS Shapefiles | Tableau Software

You can use the filled maps chart option to fill worldwide states and provinces and U.S. counties with built-in geocoding. For maps that require more detailed areas, such as cities, zip codes, area codes, or custom areas, use the ArcGIS ShapeFiles to prepare and define a file that can be imported into Tableau Desktop as a polygon layer. For more general information about polygon filled areas, see the Creating Polygon-Shaded Maps article. In an ArcMap view that contains the polygon shapefile layer of interest, verify that the polygon is in a geographic coordinate system using decimal latitude and longitude units, such as GCS NAD 1983. If it is in a projected coordinate system, use ArcToolbox to project the shapefile to a geographic coordinate system. Launch the ET GeoWizards tool in ArcMap and follow the step-by-step wizard to output a Polygon to Point feature. Be sure that the output points are the Vertices only. [ID] or [ET_ID] Either of these two fields can be used for the Level of Detail shelf.[ET_X] This field corresponds to the longitude coordinate of the record.[EY_Y] This field corresponds to the latitude coordinate of the record.[ET_ORDER] This field contains the draw order of the points and is used in the Path shelf for the polygon. When ready, save the updated file to a data source supported in Tableau, such as an Excel or Access format. Source.
