import progress

Anyone know how the other states are going? Is there any time frame? Anything I can do to help?

I noticed today that GNIS data for San Francisco has appeared in the last few days, so California must be ongoing -- StellanL 09:32, 11 March 2009 (UTC)

replacing gnis node with a polygon

Some of the features (like cemeteries, schools, islands) would be better represented by a polygon. Should we be copying GNIS specific tags to the entire polygon, or leaving the gnis node? If we make new polygons and copy over GNIS data then we could use a Centroid algorithm for updating USGS as to the position of things. Tylerritchie 18:53, 3 July 2009 (UTC)

wetlands vs. wetland

For the GNIS import the plural form is used:

FEATURE_CLASS OSM Tag(s)
Swamp natural=wetlands

Other people seem to be using the singular form: natural=wetland

See also tag usage of natural=* at osmdoc [1].

It might be a good idea to standardise on the singular form, as it is more common in OSM to use a singular form when tagging. --Cartinus 17:37, 8 November 2009 (UTC)

You are right. I therefore changed the spelling of all ways and nodes tagged with "wetlands" to "wetland" (changeset 3916547). Could anyone make sure that future imports use "wetland"? --1248 18:02, 19 February 2010 (UTC)
I just changed it to natural=wetland + wetland=swamp. Any objections? --Wuzzy 17:48, 4 December 2012 (UTC)

Class = "Ridge" Imported?

Have all GNIS classes been imported? I have noticed at least two classes that do not show up in an area where other GNIS features appear. One is "Ridge", the other is "Pillar" (as in a rock formation). For those of us that spend time in the back country, these are important features.

Tool to check GNIS database against OSM

I was wondering if there is a tool to check the GNIS database against OSM? It has been almost two years since the database was imported, and I think it would be useful to find out what has changed between that import and the current GNIS database and what has changed in OSM. Looking in my area, there are a number of features that seem to have been replaced with an area (i.e. for lakes), but the gnis:feature_id wasn't copied over. The simplest thing to do would be to spit out a list of what's missing in GNIS vs. OSM, but much more could be done. - Joshdoe 18:40, 31 January 2011 (UTC)
