mapping migration flow
How can I create proportional symbols that show the migration flow (with arrows) from one state to the rest of the country? I need to create a map showing the inflow and outflow of people from the states of NY, NJ and PA.
Mapping Center Answer:
There isn't a way to do this automatically yet. That is to say, right now we do not support flow mapping as you described it. The only way to do this is graphically but we wrote up the instructions for you in this blog entry: Making maps that show flow from place to place.
However, we have gotten this request beore. I'd like to suggest that you submit this on the ArcGIS Ideas page, or if it has already been submitted, vote to support it so that it receives higher priority.
