I tried the polygon mapping using Tableau 8.3.1 and it doesnot work. I had to created another excel file with NSW suburb long and Latitude which enables me to map the data on the map but need to get the polygon data for suburbs instead of LGA.
As per this blog tableau 8.3.1 has built in LGA geocoding but my data is based on suburb
Please find attached my sample workbook.
Thanks in advance.
Check out this post on my blog:
You can get the suburb boundary data from there already converted into a format for use in Tableau. The file you want is the SSC ASGS role.
