I need to create a custom basemap for use in AGO. It needs to be highly stylized, and I've gotten pretty good with ArcGIS Pro so I created my map there.
Data: This is a basemap that I will eventually need to use again, for multiple clients (i.e. multiple municipalities) over a significant span of time. To address that issue, I pulled all of my data layers from open source feature services. They're mostly coming from the State of Michigan, with a couple from SEMCOG (regional entity), and a couple of counties. This way my data layers will stay up to date for a large geographic region. I might have to recreate a tile package on occasion, but the Pro project will not need to be updated.
