Does anyone know where the Generate Service Area gets its road network from? I run it in Pro 1.1 without a street layer or anything, and I get an output that follows the road network. It seems to be working fine and seems accurate, but I'm giving a presentation on this study next month and I know there will be people asking where the data is coming from!
I looked all over the Pro site and can't seem to find anything. Anyone have any ideas of where I can find the info?
Questions I need to be able to answer:
1. Where is the road network? Through which service is it maintained (GoogleMaps, OSM, etc.)?
2. How does Pro know the speed limits? I assume through whichever service the data is from?
3. Is there an error margin? It seems correct so far, but if a margin is established, it'd be good to report.
On a good note, it looks really cool
