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 things like this, where the coastline goes very far upstream: https://www.openstreetmap.org/way/14763476#map=11/-12.4279/132.4683 <https://www.openstreetmap.org/way/14763476#map=11/-12.4279/132.4683> In other cases, the coastline is farther downstream, like where the Pine River stops here: https://www.openstreetmap.org/way/159813122#map=14/-27.2842/153.0761 <https://www.openstreetmap.org/way/159813122#map=14/-27.2842/153.0761> We were thinking the second example is better. If that’s the case for the Alligator River we would put the coastline here (which is also where the GA Surface Hydrology polygon has the river starting) https://www.openstreetmap.org/?mlat=-12.2296501875&mlon=132.402678198#map=15/-12.2293/132.4083 <https://www.openstreetmap.org/?mlat=-12.2296501875&mlon=132.402678198#map=15/-12.2293/132.4083> and change the existing coastline to riverbank. Please let me know what you think.
