Help with creating shapefiles for MA cities/towns

IT EMAIL Email Feb 7, 2017 10:56 AM

I am working on a project that requires mapping based on custom polygons for MA cities and towns. I found the data publicly available here: MassGIS Data - Community Boundaries (Towns) from Survey Points

I attempted to follow these instructions to use QGIS to convert the GIS file to a CSV: Create Tableau Maps from Shapefiles

Unfortunately, I am still not seeing any geographies in Tableau.

Any ideas for other ways to do this or why it isn't working? Alternatively, has anyone found this data publicly available in a form Tableau can read?

Please find the following:
One page word document with three screen shots showing two ways to approach
Version 10.1 approach based on an Alteryx Shape File to Polygon point file conversion (see Alteryx workflow screenshot). Note; results in 647,717 marks which is clearly not ideal
Version 10.2 BETA version using the new BETA Spatial File Connector Coming Soon with a new Geometry Data Type. Note: results in 351 marks
Glad to walk anyone through this and/or always interested in other approaches Best Douglas

Glad to discuss this with you or anyone else not that Tableau provides a native connector to spatial files this should be straightforward. i am at 571 338 9728 anytime Best Douglas

Did you figure this out with 10.4?

With the new spatial connector, you can connect to one spatial file (I chose the TOWNSURVEY_POLY.shp file) and double-click GEOMETRY to instantly draw the borders seen below. I put the dimension "Type" on color for fun.
