[Talk-us] 25or6to4 NHD imports

[Paul Norman]

Minutely diffs are currently running from
http://planet.osm.org/redaction-period/

You should read the caution first before consuming.

 

>From what I saw the imports were fairly clean. Some large objects, but
that's to be expected with the large lakes in the region you were working
in. If you're reviewing each object as you add it, which is certainly
manageable with a size limitation, then this kind of falls into the grey
area between an import and not.

 

If you're running shp-to-osm.jar with the rules on the wiki you should be
careful on some of the less common features. Lakes and such are likely to be
fine but some of the less common NHD FCode to OSM tag mappings aren't great.
Again, you're not likely to run to big issues if you stick to > 0.5 square
km areas since this will exclude most of them.

Howdy,  After discussion with Toby, I am updating the list with my import
efforts.  First, hopefully this message goes through, as none of my previous
ones have worked...  Second, was introduced to a better way to create a new
account, so the TexasNHD account will be used for uploads.  Third, I have
been taking the NHD shapefiles, pulling out only the areas more than 0.5
km^2 for this round of uploads.  This edited shapefile was run through
shp-to-osm.jar with the NHD rules file on the wiki, then uploaded piece by
piece through JOSM.  For error checking, have then redownloaded the areas
that were uploaded and doublechecked for errors/open ways/dupe notes/etc.
Once (if) we have minutely diffs going into the APIs, I will do a
triplecheck for any more glitches.
