 riding on the assumption that we'll have something like 'tiger:reviewed =
 no' (with editor support) to mark unreviewed areas. Ideally, an 
 indication
 that an address is unreviewed would be passed along by any services that 
 use

 So, who did volunteer to write that editor-support?
 What editor is it?
 In case of josm, do you have the ticket-number for this 
 enhancement/plugin?

   It turns out that the same tiger:reviewed tag works for address 
interpolation ways.   The addr:inclusion tag could also be used for this 
data to mark what has been updated, but people are likely to forget or not 
know to update either one after they fix the data.

No, the problem is that TIGER uses privacy-obfuscated potential

Yes, in some locations the error is small - in particular if the

other locations the error is much larger.

TIGER is fine if you don't have anything else.  But that's not the

The *data* can't be copyrighted, but the format and presentation of it

 In San Francisco, for divided highways the old TIGER data used to bow in to 
 a point every block and we had, I think, automated ways to split those out 
 in to two straight lines. This is reflected with little bows on the address 
 lines at each intersection - see guerrero for example.
 
 What really needs to be done for TIGER addresses import is match the
 streets from TIGER to those in OSM (which should be easy since they
 all still have the TIGER id's) and generate the address geometry based
 on these.  Otherwise someone will need to do all of the geometry

I very much agree with that.  But TIGER roads are half-decent
approximations of what we want in OSM.  TIGER addresses aren't, at
least not in all areas.  If you want to add them in areas where the
data is good, and there's no better data available, fine.  But please
don't add it to Hillsborough County, Florida.  And preferably don't
add it to any county in Florida without first checking with the county
to see if there's better data available - because chances are there
are.

See http://wiki.openstreetmap.org/wiki/Image:Qgis.png for an example
of something I whipped up for my neighborhood in a few hours (which is
about how long it took me to figure out the query select
ST_Difference(ST_Boundary(a.the_geom),
ST_Boundary(ST_Union(b.the_geom))) as the_geom into quick_test from
neighborhood_parcel as a join neighborhood_parcel as b on a.gid!=b.gid
where ST_Intersects(a.the_geom, b.the_geom) group by a.the_geom;).
I've got address information for every one of those parcels.  This is
much better than the TIGER data, if you want actual addresses and not
potential address ranges.

I haven't uploaded it yet, mainly because I want to do it right.

- I have done a survey with GPS
- I have verified location on Yahoo is correct
- One of the above AND name or any other attribute is correct
- Everything is correct and it's as if I had entered the data myself

Everyone has different thresholds when to remove such a tag, some may  
just remove it because it clutters the default josm drawing and it is  
practically impossible to use josm in US without patching it.
And I have not yet started to think about vandalism.
OSM will never work like a DB with authoritative characteristics.  
follow the basic rules. map what's on the ground. as I mentioned

accept broken imports as better than survey osm is just a me to thing

it's called Google maps and has much better infrastructure than osm  
will ever have. they have imported all county data, park data, tiger

That way the different shops (or banks, law offices, dentists, ...) in

Re: [Talk-us] Status of TIGER tag removal

2009-11-14 Thread Frederik Ramm
Hi,

just a quick status report. The process of removing unnecessary tags 
[1] has been running for 95 days now, and has processed 113 out of 
roughly 175 million nodes. That's a little slower than expected and if 
the process continues at that speed, I'm afraid is going to drag on into 
the first half of January, 2010.

I will however try a few tricks to achieve a speedup (perhaps run a 
second process during off-peak times).

Other than that slight slowdown, everything looks fine. Data users 
should already be seeing reduced extract sizes across the whole US (the 
update proceeds county by county but in random sequence, and also 
re-visits counties with large numbers of updates).

Bye
Frederik

[1] The process will drop source, tiger:tlid, tiger:upload_uuid 
and tiger:county from all nodes which have at least one of the three
tiger tags. It will not drop source from other nodes. If a node is
found to be tagless after removing these, and the node is not used by
any way, it will be removed entirely.

2009-11-14 Thread Dale Puch
What I know of it is the tiger ID came from the ID of each unique item in
the tiger DB.  A road segment that had an address range was one, the next
address range was another ID.  Basically each intersection to intersection.
All well and good except in OSM those would all be septate ways, so they
were combined along with the ID's.  This might have worked a lot better if
they were combined as a relation, but that wasn't an option then.

I think the idea was that the ID's could be matched up later if any updates
were needed.  The amount of poor quality data in tiger and the editing done
to it made this a LOT harder than I think was originally planned on.

Now there are a ton of roads that have not been touched since the import,
and these may be matchable and machine replaced with newer data.  The
problem as I see it is the boundary data between new and hand edited.

So for unedited roads the ID's MAY be useful.  While that data may still be
on the server in the history, most work is done against a planet file
extract that does not have that history.

I think what we need is to find some good SQL gurus that can figure out the
best way to match and process this stuff on the DB side.

 Unless you can point me to some documentation as to what the tiger id
 *means* (*), I'm not going to think about it at all.  Sometimes I keep
 it, sometimes I delete it, sometimes I delete the whole way and create
 a new one in its place (without any of the tiger tags).  And I'm sure
 I'm not the only one.

 (*) I take it to mean simply that the originally imported way came
 from a certain TIGER way, which is preserved in the way history

Dave was probably reacting to the wording. The phrase is often used when
making a promise or threat, as in That's just not happening while I'm
in charge.

I interpreted  the That's just not happening. as simply a pessimistic
view of the likelihood of it getting done; People will not find it easy
and interesting to fix up lots of bad TIGER addressing data.

Just my $.02

  no one is interested to cleanup crap after a bad import. 

I am.

 tiger import was great from technical  
 point of view but didn't allow to build a community from scratch. 

I didn't want to build anything from scratch.  I'm simply not that
motivated to go out and wander everywhere mapping everything.  If we had
to start from scratch, I would not do it.

 no  
 one is motivated to fix this broken data. 

I am.  I have fixed a lot of it.  And in doing so, I have made complete,
correct map areas, much larger than I ever would have done by starting
from scratch.  

Be careful about making absolute generalized statements like everyone
and no one.

I'd prefer that people preserve the TIGER data whenever possible.  It's
not a primary concern and don't let it slow down your mapping, but it is
a useful data point.

Let's say we're doing a future TIGER import.  Updated roads will have
the same TLID between different TIGER revisions and that gives us a good
starting point.  It's a third bit of data to augment any matching
decisions we make based on location and name.  We can get along without
it, but it *IS* useful.

Way history is fine as a backup, but tracing that through splits and
joins is not going to be easy.  It's much more straightforward to just
get it directly.
