Re: [Talk-us] US Hydrographic Data
According to the 105th page of the first PDF of specs on http://rockyweb.cr.usgs.gov/nmpstds/nhdstds.html, they use 1D linear features for rivers when the river is too small to represent as a 2D area. There is a relatively large set of rules that they used to determine the size. Also, if there are names are known (but not included in the data), then we should add them using the GNIS interface at http://nhd.usgs.gov/gnis.html.

Re: [Talk-us] US Hydrographic Data
The NHD viewer (http://nhdgeo.usgs.gov/viewer.htm) shows areas for rivers that are "big enough" (I see areas for the Mississippi, for example). I haven't tried converting an area that has such a river yet, but I'll bet the script handles it.

Re: [Talk-us] US Hydrographic Data
Is there a reason the NHD treats rivers as linear features instead of areas? Is area data present for the river banks that isn't being converted yet?

Re: [Talk-us] US Hydrographic Data
The data that was uploaded has the name tag on most features, but now that I zoom in some more, I see that the water bodies don't render their names until zoom 16. Also, marsh areas aren't rendered. Perhaps these modifications could be suggested to the osmarender list?

Re: [Talk-us] US Hydrographic Data
Ian, When I zoom in, some of the rivers are labeled, others aren't. This could just be a rendering issue. Do the names show up in the OSM file? Or perhaps the original NHD data is simply missing names for those features? - matt On Fri, May 2, 2008 at 6:46 AM, Ian Dees <[EMAIL PROTECTED]> wrote: > [EMAIL PROTECTED] is starting to show the data I uploaded yesterday: > > http://tah.openstreetmap.org/Browse/?x=1971&y=2935&z=13&layer=tile > > It looks like the water bodies aren't given "name" tags. > > > > On Thu, May 1, 2008 at 2:17 PM, Ian Dees <[EMAIL PROTECTED]> wrote: > > > I'm 80 minutes away from finishing an import in this area: > > > > http://tah.openstreetmap.org/Browse/?x=245&y=367&z=10&layer=tile > > > > I'll probably have to "fill in the holes" for islands and maybe slice up > the extra-long ways (both are TODOs on Matthew's python script I think). > > > > > > > ___ > Talk-us mailing list > Talk-us@openstreetmap.org > http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk-us > > -- Matthew T.

Re: [Talk-us] US Hydrographic Data
[EMAIL PROTECTED] is starting to show the data I uploaded yesterday: http://tah.openstreetmap.org/Browse/?x=1971&y=2935&z=13&layer=tile It looks like the water bodies aren't given "name" tags.
