Folks - any insights would be helpful on this. In general, is there a way to specify a new hierarchy in custom geocoding?
Also - for clarification - I'm looking for hierarchy in filled map capabilities. I have been able to make a hierarchy using lat/long, but am trying to get a filled map that rolls up. Thanks!

Dear Jane Yang,
To have a working hierarchy in the geohack with tableau you will need to provide the hierarchy within the custom geocoding files.
To elaborate, if you have Country/Division/District/Upazila, this means you will have 4 .csv files, in each of them you will have the role (Country/Division/District/Upazila) and the lat, long coordinates.
In order to add the hierarchy you will need to provide each role with the corresponding higher level assignment in a new column. Thus, in your Upazila.csv file you will need to have 6 columns as follows:
Upazila Code | Distric Code | Division Code | Country | Latitude | Longtitude
Each upazila code will need to have the corresponding information. You need to do this for all files.
For more information on how to do this I refer you to the following link:
I hope this helps you out.
Thanks, Nicolas. I stumbled upon that very link a few days ago and am able to implement hierarchy locations (e.g. dot marks) but am trying to figure out how to do a hierarchy with a filled map (i.e. using polygon shapes, rather than dot marks). I've got .shp files with the polygon shape info, but not in .csv.
As far as I know I don't think you can make hierarchies with polygons due to the levels of detail you need to place for just one layer (3 different ones).
In order to achieve filled maps with a hierarchy you will have to take a look at changing your polygons into a custom geo hack.
For more information about making a custom geohack can be found on this page:
Combine the geohack with my first post and you will have filled maps based on your polygons with hierarchy.
