Re: [Talk-us] GNIS Import
There's a copy tags feature in JOSM that doesn't seem to work. That's about the only way I know of right now. Pasting tags from node to way did not work for me, as recently as just a few weeks ago. However, I tried it just now on the current version 1515 and it worked. If there are tags on the way which you don't want to overwrite, just delete those tags from the node before copying. Not a good solution for the general case, but for the GNIS import, the node is just going to get deleted anyways. - Alan ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Perhaps it is similar to potlatch, which only allows you to copy way tags to other ways, and nodes to other nodes. -- Joseph Booker signature.asc Description: PGP signature ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [Talk-us] GNIS Import Done
While GNIS might not be perfectly accurate in geoposition, it is the authoritative set of geographic names for the US. It contains features that are on no other map or spatial database. Until now, anyway. ;-) Karl ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [Talk-us] GNIS Import Done
If you go to the Board of Geographic Names site (http://geonames.usgs.gov/), it indicates that all elevations are from the National Elevation Dataset. (Which is probably what Garmin uses as well.) NED doesn't really have the spatial resolution to resolve features as small as the exact tops of mountains.

Please see the wiki page [1] for more details. As several of you have messaged me and posted on this list, there are some problems with this data. Let me try to explain my thought process: 1. Since the resolution of the information is fairly low (i.e. a clinic, hospital, doctor's office, retirement home, etc. are all tagged hospital in their data set), I have absolutely zero problem with retagging data if you come across a feature that is incorrectly tagged. Not like you need my approval, but that higher resolution of info might convince the GNIS board to add some more tags to their data set. 2. I'm planning on taking the planet dump and grepping out all of the GNIS data. This will be used to generate diffs that we can send back to the GNIS board, who has the option of putting it back into their data set. 3. If there are already OSM features in your area for a certain node that I imported, feel free to delete my node, but please merge at least the gnis:feature_id tag from the GNIS data so that we can keep track of future name changes. -Ian [1] http://wiki.openstreetmap.org/wiki/USGS_GNIS ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us -- David J.

What about features that are polygons in OSM but nodes in the GNIS data? Since all features in GNIS are nodes, I will just take the centroid of the polygon to be the point that might end up in GNIS. Feel free to apply the gnis tags to polygonal ways. The more important data I think would be changes to the name or classification and whether or not it even exists. Will you also be grepping the planet dump for features GNIS includes but doesn't have an item for? ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Sorry if I sounded mad in my message. :) I still question the value of this data given my (brief, informal) survey of what it brought to my local area. I think I may have also deleted a few nodes where I had already mapped the feature. I can go back and transfer the GNIS tags to the existing feature if you think that would be helpful. It would be helpful to have the GNIS feature_id on existing data if it's talking about the same thing. There are lots of nodes where the name has (historic) or similar at the end, which means that the feature no longer exists but is recorded for historical purposes. I thought I had deleted those from the data before import, but it looks like most of them got imported. I was planning on searching for those IDs and deleting them when I scrape through the planet dump next week. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

That would eventually push a delete the less correct data point change into GNIS, which is a good thing I think. I hope soon to start some analysis based on the names of GNIS nodes. Initially to attempt to recategorize secondary medical facilities such as clinics from true hospitals. I will note that I'm not sure what to do with secondary facilities once I have sorted them out; amenity = hospital really doesn't see appropriate; all other proposed tags seem to have been voted down. We might drop them, or assign them a non-standard tag for later reclassification. On top of that, it might be appropriate to perform some sort of name based analysis on nodes with the same class and within a distance of N units from each other. For items like schools, stripping common words from the names (Elementary, High, Junior, Middle, School) and comparing the remaining values one word at a time might provide a quick list of redundant nodes for review. If anyone is interested in participating with this effort on a more national level, I'd welcome the help. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
