Flow Map - assistance

Anonymous User · ‎06-13-2018

Hello Folks,

I'm a first timer visiting GeoNEt and I'm wondering anyone has any experience creating a Flow Map.

I'm open to any and all ideas.

I've tried using the Flow Map Generator and It throws an error regardless of my imputs. I'm on a windows 7 machine running ArcGIS desktop 10.4.

The error is " Source feature class contains more than one feature". Regardless of how I limit

Thanks for the time,

The tool authored by Brad has been updated and should work with 10.4. Here is a link to the blog update which contains a link to the new tool as well. It is important to have only Source feature for this type of map. It is a bit confusing but the source feature does not really act as the source in the flow map. It is the destination features that carry the quantities that actually flow back to the source. The map ends up depicting how stuff flows from the source to the destinations but when the tool actually runs the flow is in the opposite direction.
