    Roll up DMA boundaries to Region

    Mark Weinmann

      I have created a map with custom polygons to split the US up into DMA's using various links and downloads provided by this thread: Custom Filled DMA Map using Richard's Shape file utility...


      I have the need to roll these up by region, so I altered the CSV containing DMA boundary points (attached) so that it also specifies which Region that particular DMA belongs to. Here is a snippet of it's layout



      What would I need to do in order to create a boundary file rolled up at the Region level?
