[talk-au] Putting streams into OSM

[Tom Brennan]

DCS Base and Topo don't distinguish between perennial and non-perennial

That information is available in the NSW Water Theme data eg:
https://portal.spatial.nsw.gov.au/portal/home/item.html?id=7b0e959effd749c788d304a4179abf8a

That data is licensed under CC BY 4, which I think we have permission to 
use. (I haven't used it, but if allowed, it would make sense rather than 
tracing individual lines).

Though I'd be a bit dubious about some of the things that are classified 
perennial vs non-perennial. It looks algorithmic, and not entirely 
internally consistent! Pretty sure I could write a better algorithm.

cheers
Tom
