I work as a travel demand modeler for the New Mexico DOT. That entails a fair amount of GIS work, which is why I decided to join the community. I hope to hear how others handle workflows and troubleshoot issues when the software has difficulty digesting a series of operations.
I currently use ArcMap for my work, and will eventually become familiar with ArcPro.
