Re: [talk-au] Correcting inland water features

I noticed this dataset too, but could never figure out how to open it with JOSM. Andrew Harvey, have you checked out these files? And do you have any plans to convert them? If we plan on doing a wider scale import I would suggest separating each stream into its own .osm file so we could check

More specifically... The watercourses are flagged as perennial or non-perennial or null *Should all those flagged as non-perennial be tagged as intermittent? Seems to be too few perennial but as others have mentioned Australian watercourses are predominantly intermittent.

I am struggling with how to use "ephemeral" rather than the "intermittent" tag, particularly when it comes to on-the-ground verification. I have travelled in some rural and outback areas in western NSW and Queensland and, to a lesser extent, in South Australia. I also regularly look at

Re: [talk-au] Correcting inland water features

Thanks for the feedback and suggestions everyone, that’s very helpful. We have also added AGRI to our list of sources. Where the inland water meets the coastlines, we have seen a few different styles of modeling so I wanted to see if you had a local policy about it. In some cases we’ve seen

Re: [talk-au] Correcting inland water features

Agreed with Warin and Ewen. I'd like to point out the AGRI imagery [1], yes it's old (2006-2011), black and white, and missing parts of the imagery due to cloud and seams, but it may help as an extra source to compare. It's good enough to make out rivers and it should be accurate positionally

Andrew, Welcome. As Warin mentioned, the vast majority of waterways are intermittent outside the great dividing range and coastal areas and a map, source and accuracy unknow is available as an example
