I'm having a hell of a time so any help would be appreciated.
I want to extract the latitude and longitude of the Health Authority boundaries from the zip file below. The ultimate goal is to import these coordinates into Tableau.

1Hi, you might want to consider posting the page where you downloaded the boundaries from ... not the zip file. I think quite a few people will be a little suspicious of clicking on a self extracting link! Why do you need the coordinates in Tableau, what are you planning to do with them?– Andrew TiceJun 17, 2013 at 3:11

1Is this the Tableau you are referring to?– PolyGeo ♦Jun 17, 2013 at 4:07

Thanks for the responses. Yes, it is for Tableau Software. The link for the shape files is under Health Boundaries: Health_Authorities bcstats.gov.bc.ca/StatisticsBySubject/Geography/… I am wanting to try out the mapping function within Tableau so that is why I am trying to learn how to do so!– user19190Jun 17, 2013 at 17:16

1Are you looking for the coordinates of the vertices making up each polygon? the centroid? the extents?– PeteJun 17, 2013 at 18:56

I am guessing that I need the coordinates of the vertices making up each polygon. I have also reviewed "Creating Tableau Polygons from ArcGIS Shapefiles." I also tried to extract the coordinates via ArcGIS but it did not work! I had a trial version which did not allow me to import my own shape files!– user19190Jun 17, 2013 at 20:49

Tableau has a knowledge base topic on this: Creating Tableau Polygons from ArcGIS Shapefiles.
The topic says to use ET GeoWizards tool to help prepare the shapefile, and that only free functionality from ET GeoWizards is needed. The Polygon-to-Point wizard is used, so you may be able to use the Geoprocessing tool, Feature to Point, if you have an ArcInfo license.
Tableau can now connect to shapefiles natively, and import polygons.
