Questions:
What default network layer does the ArcGIS Pro Generate Service Areas tool use? Is the layer available anywhere to be used apart from the tool in Pro or ArcMap Desktop?
Context:
I have been using the Generate Service Areas tool in ArcMap Desktop with the input network layer that I created using a North Carolina road layer with distance and drive time information. The resulting service area layer seemed inaccurate so I attempted to run the same process in ArcGIS Pro using the Generate Service Areas tool. This result seems more accurate, so I was wondering what the default network layer is used for this process/if it is available for me to use in ArcMap Desktop. (I would prefer to use ArcMap because I have created custom geoprocessing tools that work in ArcMap and would have to make alterations to the code for it to work in Pro)
