Hi Ian,
I should be able to convert the NHD data sometime in the next week or
so. Also, if/when you want the original data, let me know.
For the conversion, do we want medium or high resolution?
Re: the import status map, I don't know how to make an actual map from
them....short of simply providing a KML file and saying "go look on
Google Earth", what formats are most useful for making an overlay status
map? (I could do that conversion and hand it off to someone.)
cheers

Yep: if you have the ability and time to cut the national dataset into
subbasins I'll give you an SFTP to upload them to and I'll start
converting them to OSM.
From there we could add links to the pre-converted subbasin OSM bundles
to the wiki pages.
Bonus points for converting the subbasin boundary files to
KML/GeoJSON/GML and overlaying them on a "import status" map that a user
could click on to find their subbasin. I'd be happy to host all this.

Hi Y'all,
So let me see if I can summarize where we are so far...
- I could cut the NHD data down to sub-basins. It would not be a
perfect cutting (e.g. each sub-basin might need a little bit of data
"hanging off" since the raw data isn't cut on sub-basin boundaries)
but it would be pretty close, and we expect users to manually check
their imports. I could also potentially convert the shapefiles to
.osm format on a sub-basin basis.
- It would be nice to make it easier for users to find their
sub-basins. I'm afraid I don't know how to use the mapnik tool
chain to create a slippy map though. (Left to my own, I would
probably convert the sub-basin boundaries to KML...that makes me a
heretic, right? :-) We could also just post the boundary shapefile,
but some users may not be comfortable with shapefiles.
- Importing on a sub-basin basis should be possible in JOSM, if not
a bit of a mouthful. Importing via potlatch2 vector layers should
be possible - others have seen this work although I have not.
cheers
Ben
