Re: [talk-au] Putting streams into OSM

Thanks for the various comments on the thread. Having looked at the data in detail, my inclination is to bring in the remainder of the named watercourse data for NSW (the Hawkesbury and Sydney Coast/Georges River catchments according to Andrew Davidson). It looks like there will still be a

Re: [talk-au] Putting streams into OSM

Absolutely no offense was taken, hence the winky ;)... it was solely the moment of realisation of my current ignorance on the matter... which I don't take as a bad thing. It's a new opportunity to learn more, so much thanks for taking the time to respond comprehensively and not just 'RTFM' me.

Re: [talk-au] Putting streams into OSM

OMG... I am drooling looking at what you've done here. Just switched the 0212 in your overpass query for 0210 (Hunter River) and zoomed into the Newcastle region... and voilá: https://overpass-turbo.eu/s/1vuY Was this the changeset that did your GA import for my area:

Hey stevea, was this warning on relations due to any particular remark in this thread? ... I feel attacked! ;) given I've used iD to edit relations quite a bit: I don't usually edit them, but more just adding new ones. Except for re-adding ways when they got deleted from a route, when others

Re: [talk-au] Putting streams into OSM

I've said all this before: while editing relations in iD is technically possible, it is tedious and difficult in the opinion of many. A great many existing relations have also been broken by people using iD (I can't count how many I have personally experienced). I find editing relations with

Re: [talk-au] Putting streams into OSM

Regular area shapes have a node limit that is quickly reached when mapping rivers/lakes. Islands/islelets are also not properly cut out when they are created within a water body. The solution to both of these issues is creating a multipolygon with relations. On a side note, this is a

Re: [talk-au] Putting streams into OSM

My main area of interest from a stream point of view is the Hawkesbury Catchment, outside the Sydney suburban boundaries. I haven't been involved in any imports so you'll have to excuse my ignorance. Could the dataset be split into say urban/non-urban and the non-urban parts imported? Or do

I hadn't seen that page until Andrew Davidson mentioned it earlier in the thread. But the NSW Water Theme data falls under the DCS Foundational Spatial Data, which is listed as having a waiver, and thus usable... [And I probably should have been more specific with the wording - I knew that

I map streams on the regular. Given most of what I map is bike + running single-track, streams are helpful as a clue to the local topography. But I’ve also made relations for all of our local streams and creeks; go to the Newcastle area and search for Ironbark or Cottage Creek for instance… it
