This is really cool. I have a few comments and questions about how this
will work, but I think this will be a great way to import the NHD.
1. Can you edit points and locations before you approve a feature?
This would be nice for both inaccurately located points, but also for
integrating with existing water features.
2. I didn't quite understand marking feature as complete. In your
email, you said that you marked ponds that didn't show up as complete.
Could there be different levels of approval/rejection of objects so that
complete= move into OSM database, remove= remove from import database,
survey= can't tell from bing imagery.
3. A few tagging nits:
a. I still think that 46006 streams without names should be included. I
don't know if it is from being in a wet place, but many streams in NC
that are a couple meters wide, have road bridges over them and flow
noticeably have no name (at least in the NHD).
b. I would rather have the dam as way features than node features.
Although it probably would be best to not have every little water pond's
dam imported.
