Re: [Talk-us] NHD data changes

The viewer has changed. http://viewer.nationalmap.gov/viewer/nhd.html will bring up a map you can use to download NHD data. This viewer does not work in Chrome but does work in IE. Subregions are pre-staged downloads, the others will take some time before you can download. Firefox also works. Subregions can be directly downloaded from ftp://nhdftp.usgs.gov/DataSets/Staged/SubRegions/PersonalGDB/HighResolution / Most subregions are available as a new NHD 931v210 file but some are still being generated. 2. NHD data is now available only as File Geodatabases (File GDBs, .gdb) and Personal Geodatabases (Personal GDBs, .mdb). My understanding is the default builds of QuantumGIS and GDAL on Windows can open Personal GDBs. On linux gdal can be compiled with drv_mdb or the pgeo driver can be used for Personal GDBs, or the filegdb driver can be used for File GDBs. This is moderately technical. I was able to download a .shp file from the viewer. It had changes in it date in 2012, so I assume that it is current.

Re: [Talk-us] WTF happened to Bing's imagery of Mackinaw City, MI?

Re: [Talk-us] WTF happened to Bing's imagery of Mackinaw City, MI?
Wow, this is messed up. I just took a look @ Google's imagery and it isn't blacked out. Looking at it, I didn't see any reason for it to be blacked out.. http://g.co/maps/yxrkg So, it must mean that somebody in Bing is doing this for fun possibly. --James ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

I'm not sure what you mean, because I am not making that assumption at all. You mentioned use of the history to access the TIGER tags. Yes, I said if a bot is smart enough to go through the history tags, then this *does* provide an advantage over data consumers doing it themselves. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

I'm sure we see error rates that high now in OSM and we find them acceptable. A computer that's acting conservatively will actually produce far lower error rates! But its error rates are potentially much more annoying. Doctor Martin Luther King Bolevard is one thing. Drive Martin Luther King Boulevard is another. The latter will be much more difficult to find at a later date and flag for review. Maybe you won't make that particular error, but you're going to have to be really careful to avoid making any errors like it. And relying on the TIGER tags may or may not help. I wouldn't be surprised if many of the TIGER tags themselves are screwed up, based on the kinds of mistakes I've seen in TIGER data.

And if we're going to make so many mistakes (1/1000 means thousands of mistakes), I'd rather it just be left as Dr Martin Luther King Blvd. Yes, we can't stop people from making mistakes. But we can refuse to allow thousands of mistakes to be added, for the sake of removing abbreviations which aren't hurting anyone in the first place. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
