Yes, I think now all land borders are completely mapped. Nice piece of work. > So, what's next to complete the national/state borders? > Good question, I would probably start with the national border. These maritime boundaries are rather messy, just have a look at the yellow line and the brown area in [1] or read the description there. For this I see two different methods: (a) Do the pure-OSM approach by deriving everything from the coastline with some guessing for the straight segments. (b) Try to get permission to use the official data [3] Here I would definetly favor (b) - simply because to me the only accurate definition of the baseline is the official one. But of course I don't know at all if there is a chance to get the permission to use the data in OSM. If this doesn't work we would have to work on using the coastline, somehow generate a baseline, and from there calculate the territorial waters. The piece looking most diffcult to me would be to generate the baseline, given the topography of Australia's coastline and/or looking at [1]. Any thoughts or suggestions are highly welcome!
