Assuming it runs off a REST API, it's probable that you could pass GET commands, but without knowing the API, it's a real assumption.
It's possible to put ArcOnline maps into a dashboard, you need to make it public and then use the URL. But that's half the battle, because you are going to end up with a mass of URL filters to match the ESRI parameters.
I was told to expect an ESRI -> Tableau connector somewhere in late Q3/early Q4 this year (that's from ESRI devs, not Tableau); which will make your (and mine) considerably easier.
Allan, so it is safe to say you cannot add it using the WMS instructions at http://kb.tableausoftware.com/articles/knowledgebase/map-data-wms ?
And, how did you get it into the dashboard, that's pretty cool! Here's a public one: http://mycity.maps.arcgis.com/home/webmap/viewer.html?webmap=6d23c5f0842e4c62a631e06131c64926&extent=-95.3843,29.7444,-95.34,29.7733
WMS ... there's nothing stopping you creating your own Geoserver and exporting the layers into that. I couldn't see a direct WMS link, but that doesn't mean it doesn't exist...
Getting the map into the dashboard: Create dashboard, clicked
ArcGIS.com Map, found the URL, add URL to dashboard....you can also reflect your layers using ESRImap online parameters. These would go into your URL filters. It's a lot of work, but possible.
Have you heard any more on the ESRI->Tableau integration timeframe from your sources?
Our organization does a lots of work on ArcGIS and interacts with their developers frequently as well. Any chance you would be willing to share your POC?
The quickest route for you as far as I see from an ESRI environment it is to make your maps available as a WMS layer from your ARCGIS Server.
This gives you your background map layer(s).
Then for foreground analysis, you need to convert your SHP files into Tableau ready format:
Polygons: use shapetotab, or Alteryx script, or ET Wizards for ESRI Polygon to Point
Polylines: ET Wizards for ESRI Polyline to Point
Points: just need an ID and Lat/Long Pairs
Remember to convert the datum/projection of your SHP files to the same as your WMS layers.
You can house/store your SHPs using File Geodatabase (Use the JET access connector) (it's a .mdb) - 2GB limit
or Postgre SQL/PostGIS (use the 32-bit driver if going ESRI->PostGIS), or, use the DBF/SHP loader in PostGIS (no limit) : going PostGIS lets you leverage 64-bit Tableau driver connections.
So are you saying that we can bring in the data layer as well as map layer from ArcGIS separately into Tableau ? And that the data points that come from GIS will be interactive in Tableau ? like the polygons/shapes in GIS will be clickable... ?
If yes, how? Can you please describe how it can be done ??
