It is a scaled representation. The map is free of restrictions, as is the
information I obtained.

Okay. So I think, we will have to take out the roads first, and later go
into latter details in further rounds.

The map is free of restrictions. But we are not planning to scan them up and
use as a reference for OSM.

The event is scheduled for Oct 23-24.

I agree to your suggestion that the main roads would be mapped first, before
the event kick starts.

Yes. I had a confusion, how the crew could efficiently collect details of
every factors. But now, I guess we would divide the factors into subsets and
do it in several rounds.

Thank you so much for your awesome guidelines James. I would ping here as I
discuss further  with the crew.
