How to Visualize Uncertainty With Know-It-All Vector Data

It’s just the very nature of the vector data format to be absolute and binary. Yes here, cross a perfect line, no there. Such confidence, while a necessary component of storing vector polygon data, is often a lie. How do we truth up our maps so that they communicate the uncertainty inherent in any phenomenon?

Here are a handful of tips for doing just that in ArcGIS Pro. Give them a look and see if they can be helpful for your uncertain-phenomenon mapping adventures…

Happy Uncertain Mapping! John

About the author

I have far too much fun looking for ways to understand and present data visually, hopefully driving product strategy and engaging users. I work in the Content team at Esri, pushing and pulling data in all sorts of absurd ways -and then talking about it. I also get to spend time with the Story Maps team, working on fun and useful user experiences. When I'm not doing those things, I'm chasing around toddlers and wrangling chickens, and generally getting into other ad-hoc adventures. Life is good.
