    Polygon and point maps – coordinates of a point changed when overlaid on a polygon map

    Boreak Silk

      Hi all,


      I’m trying to overlay a point map on a polygon map but one of the points does not stay within the corresponding polygon boundary. 

      Attached file has two map layers (polygon and centroid). I created these two layers in ArcMap and all centroid points are within the
      corresponding polygons. However when I brought them to Tableau one of the points, Small_Area_ID 4150, falls outside its polygon.

      Its coordinates are -37.82649894830 and 144.91859794800 in the data table but when I brought into Tableau and mapped they changed

      to -37.83462 and 114.91638 respectively.


      Any idea why? How to fix this problem?


      Thank in advance.
