I have done some editing on the US side of the north shore of Lake Superior.

Hello, ,my US counterparts: Originally I have not been editing the US side of the great lakes. But with the deadline approaching I'll do some cross boarder mapping. That is unless someone on the US side of the boarder would prefer the great lakes and St Lawrence seaway.

Re: [Talk-us] Remapping coastlines
So I got some NHD shapefiles from Phil. Unfortunately coastlines are hard. The nodes tend to get incorporated into all kinds of other things like beaches, piers, etc so I can't just do an xapi query and replace things wholesale like I did with the state boundaries. So far I have only done a few miles of coastline from the Mexico border to north of San Diego. The good news is that there are a lot of the ways have been *heavily* modified by an accepting user since the original import. So for example in a way with 100 nodes, there were sometimes 4 or 5 dirty nodes. I just removed these nodes and then marked the way with the odbl=clean tag since all the original geometry had been replaced and the tagging is trivial. In a few sections where most of the nodes were still dirty I did end up importing the NHD stuff in small bits. I'm not sure how the rest of California will look. I'm guessing there will be large sections that will need wholesale replacing. I think there will also be more areas similar to San Diego with heavy modifications by accepters. But it is slow going so please feel free to jump in. I am done for now and probably won't do much more until tomorrow afternoon. So far I got up to about here: http://www.openstreetmap.org/?mlat=32.851493&mlon=-117.262337&zoom=12 Toby ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

But it keeps sending me a file geodatabase which I can't read as it requires ArcGIS or custom compiling OGR with the ESRI SDK linked in. Which... I could probably do but I have too many things on my plate to mess with that right now. It would be awesome if someone else could either do the coastlines or at least help me out by getting some usable coastline data from somewhere.

[Talk-us] Remapping coastlines
Paul Norman has been looking at coastlines as it relates to the license change. Turns out we have a big problem along the west coast. Does anyone know what the best usable source for coastline data in the US is? Surely there is something better than PGS? I poked around looking at some NHD data but didn't see an explicit coastline data set. But since I haven't worked with NHD much and, being in a landlocked state, haven't touched coastlines at all I'm looking for some input from someone with more experience on the subject. Thoughts?
