Re: [Talk-us] NHD Scripts

[Dale Puch]

I agree with Ian on this.  Remember that there is no SET way to tag,
and the wiki is for guidance to keep everyone reasonably consistent.
My feeling is Tag as you feel is warranted.  Then at least add a page
to the wiki with the tags, and why you think they are needed with
examples of where you used it.  Also to the main tags page with a link
to your examples ect. in the discussion.

I think the only thing you want to avoid is tagging the same physical
features differently from pre-existing stuff in the DB without a
compelling reason.

The only reason the OSM tags are "for" certain things is because no one has
gone in and changed the wiki page yet.

In the examples you gave, I think it would make sense to change the OSM
"definition" (as much as there is one) of the tags to mean what we want them
to mean.

To be thorough, I think we would have to break it up.  For example, we 
list a Canal/Ditch (33600) as waterway=canal, but the OSM tag is only 
for use on ways, while the NHD applies it to areas.  At the same time, 
the NHD point info gives dams as points, but the OSM waterway=dam is 
only for lines and areas.

All 3 of the shp-to-osm convertors can handle applying different OSM tags
based on the type of geometry in the shapefile.

Are you saying the we need to split up the FCode table on the Wiki page
based on feature type (polygon, line, point)?

The problem with the table, though, is that the NHD fcodes apply to 
point, line, and area data, while the OSM tags might be specific to only 
one or two of those types.  That requires a little bit of flexibility in 
actually preparing the scripts.

That table has been complete for a while on the NHD page: 
http://wiki.openstreetmap.org/wiki/NHD

Of course, now they will have to be revised for 0.6

Well, thanks to Theodore's scripts, I was able to get portions of one
subbasin imported before the DB was locked down for the 0.6 API
upgrade:

http://www.openstreetmap.org/?lat=41.7589&lon=-93.719&zoom=12&layers=0B00FTF

Looks good, although there are a couple obvious places that need some
cleanup.  It's especially nice having even partial data uploaded
because I can now generate maps for my Garmin GPSr that include water
features, something extremely nice to have on a hike.

We probably ought to start fleshing out the table at [1] in advance of
patching the scripts.

[Talk-us] NHD Scripts

[Theodore Book]

I have had some interest in my NHD conversion scripts, both from people 
interested in the NHD, and from those interested in their ability to 
specify a maximum length for an imported way.  Therefore I have placed 
them in subversion at: 
http://svn.openstreetmap.org/applications/utils/import/nhd2osm/

I hope they are useful.
