Hi Joseph, Thanks for the detailed information. I'll try these options.
For leveraging the tasking-manager, I was assuming that I'll need a team of mappers who will manually create the ways by looking at the trace I've uploaded. Is there any alternative way? e.g. I can just upload and someone else will make roads by looking at that trace.
