Re: [Talk-us] [Imports] [Talk-ca] TIGER considered harmful

I'm still getting a handle on the schemas in use for OSM, and noticed that 
concept of matching address nodes to ways when doing imports.
I'm not so sure this will be very functional for floodplain counties or heavy 
agricultural counties. We have thousands of addresses with no corresponding 
roads; the roads were wiped out in 1993 but the parcels still remain (and we 
even get regular 911 calls for those addresses on roads that have not existed 
for 15 years). Same thing for rural areas; plenty of addresses with no 
corresponding roads. As a further complication, it is very common for an 
address to have a completely different jurisdiction from the road, since roads 
are the main divider for municipal/unincorporated boundaries (and you have a 
lot of those with 90+ munis in 500 sq miles).

Can you give some details (privately if you'd like).  I'd like to see
what TIGER has in this situation.

When you say the roads were wiped out, is it still possible to
travel (by vehicle, or otherwise) over the area where the road
previously existed?  Is there still a right of way over that area?  If
so, there still should be a way, even if it's just highway=path,
smoothness=horrible/very_horrible/impassible.

This is an interesting example.  Thanks for bringing it to us.

if an area with dead data was't filled with something new no one will ever fix

 This is exactly what happened for Massachusetts.  They had better data,

 1. Data exists in a form that it can be imported

 If we don't have both of those things, it makes sense to skip doing

But, in OSM we have these relation data primitives to tie different

1) Why?

2) Are you planning on doing that with the TIGER address import?

 One way to do that is relations.

Relations could connect the points with ways, but without a whole
lot of work they're not going to be able to connect them with roads,
because a single road can consist of many different ways.  Until some
sort of relation is invented to connect multiple ways to a single
road, the best way to connect a point with a road is by using the name
of that road.

Maybe you meant that you wanted to connect the points with ways, but
if so it's unclear what connection you would want to make.  The best
candidate would be to connect the points with the way which is used to
get to the point, but that has pretty much nothing to do with
addresses - your address may be X Street, but your driveway might be
connected to Y Street.  Mapping driveways isn't a prerequisite for
adding address information, and you wouldn't want to use a relation
for that anyway, you'd want to use a way.

 They ensure that you can't, for instance, delete the road
 without also considering how deleting the road might affect addresses on
 that stretch of road.

It doesn't, and it shouldn't.

Re: [Talk-us] [Imports] [Talk-ca] TIGER considered harmful

2009-11-15 Thread John Callahan
For a single county or jurisdiction, if you delete the TIGER data and 
import more accurate local data, what do you do at the boundaries?   
County/Stare data sets I've seen usually get cut off +/- a few hundred 
feet (if that) from the boundary.  Does somebody go through and make 
them fit/connect?  or just leave them be and eventually they'll get fixed.


Listening to the is TIGER harmful talk, I for one am glad TIGER was 
imported.  It's obviously poor quality data and I never use it in my own 
work.  However, it was consistent over geography and attributes for the 
whole country.   Also, there's much less of a barrier to move a road to 
the right place then to create new ones.  Of course, maybe you don't 
want mappers you don't really understand the OSM scheme.


From my own experience, with some data there (TIGER or otherwise), I 
was able to get OSM noticed by several of my colleagues, even if the 
data was not great.  If there were mostly blank areas, they never would 
have looked twice.  I tend to agree that imports damage the growth of 
the editor community.  However, IMO this one-time import got a whole 
lot of people to start using OSM in the US.


If the goal is to reach the widest possible audience (by that I mean 
mappers AND users) than the TIGER import was a good idea.  If the goal 
is get the most accurate data, regardless of how long it takes, then the 
import probably shouldn't have taken place.  If the goal is simply to 
have fun, then it doesn't really matter, just play with what's there. :-)

Oops hit reply instead of replying to the mailing list :/

I personally favor having the possible address range in the street way
segment (between intersections)  Easier to edit and maintain, as well as
smaller memory and bandwidth when working with it.  Split each intersection,
then build relations for the streets.  This is more 1 to 1 on the tiger and
other GIS source imports as well.
One of the problems has been which side is left if the way is reversed.
With editor support this might get handled pretty well though.  Another
option is to use N S E W as the side instead, or as a sanity check in the
editor to see if it was messed up.  As I understand it the odd/even sides of
the street were largely standardized.
This also leaves it clearer to do point or polygons for individual
addresses.

 Hi all,

 I'm coming a bit late to this debate, but I just wanted to raise a fairly
 basic question, which is whether the Karlsruhe schema is the best one to use
 in the situation we find ourselves in with TIGER, where quite a bit of data
 cleanup is anticipated. The major concern I have is that if you are moving
 streets that have associated address ways, you will need to move three (or
 more) ways instead of just one. If you rename a street and the street name
 is also in the address ways, you need to rename the address ways too. But
 moving streets in a manageable way is my main concern.

 I think there is a lot of merit in considering a simple start and end range
 stored as attributes on the street (either left and right ranges separately,
 or just start and end will work in many cases). This is especially suitable
 where you are looking for a reasonable approximation to an address, as you
 get with most online mapping systems like Google, MapQuest, etc - which is I
 would think the most common use case for most applications.

 If people have the time and inclination to enter precise addresses then
 that's great and that data should take precedence of course if you find it.
 But if you don't find a more precise address (a node or an address way) then
 you fall back to looking at streets and ranges. The main challenge with
 maintaining this format, as Frederik and others pointed out, is if you split
 or join a way. But it's relatively easy to put logic in editors to handle
 that, and even if you have to do it manually, it seems to me easier to
 maintain this model than the more precise Karlsruhe schema if you are doing
 quite a bit of data cleanup.

 So this is not an either / or proposal of course - both forms could exist,
 and you search for the more precise form before the more approximate form.
 But I do think there is an argument for the more approximate form using
 address ranges on streets themselves for TIGER data in particular (where it
 is likely that we need to do quite a bit of cleanup on the data). If people
 are creating data from scratch this is also a faster way to get us to a
 workable geocoding solution for most applications (which is an area where we
 are further behind the commercial vendors than we are for basic mapping).

 Cheers,
 Peter.

I signed up for the USA 'conversion team' with the express intention
of challenging the use of the Karlsruhe schema.  Maybe you can sign up
too (even if you're not in the US).

 The main challenge with
 maintaining this format, as Frederik and others pointed out, is if you split

 that, and even if you have to do it manually, it seems to me easier to

 quite a bit of data cleanup.

The TIGER data has already been significantly degraded from people
doing just this type of thing.  The problem is, if a way goes from 2
to 100, and you want to split it in the middle (say, due to a change
in the number of lanes), you have to either resurvey the addresses or
take a shot in the dark and split it 2-48, 50-100.  That might be
reasonable if the 2-100 were accurate in the first place, but if that
2-100 were really 2-20, you've seriously screwed things up.  The TIGER
data already contains large numbers of instances of exactly this, but
there's no sense introducing a schema which makes this even worse.

On the other hand, there are other possibilities which avoid this
problem and also avoid creating multiple ways.  Join the conversion
team with me and we can talk about them.

 So this is not an either / or proposal of course - both forms could exist,
 and you search for the more precise form before the more approximate form.

As much as I hate the meme of saying +1 when you agree with someone, I
have to say +1.  Or maybe AMEN.

If you have two streets intersecting and put a number on that node, it isn't
clear which street that applies to. You could add an artificial node close
to the end of the street, but that seems a bit more messy to me. So my gut
feel is that the simplest approach is still attributes on the street.

You can also fairly easily write some validation checks that would highlight

Re: [Talk-us] [Imports] [Talk-ca] TIGER considered harmful

2009-11-15 Thread Peter Batty
When I said messy, I guess I was thinking of two things - one is doing the
import, as you mention here (which is sort of where the discussion started).
This seems quite a bit more complex if you have to split ways and insert
nodes.

The other is in writing a geocoding engine based on the data which is
produced. If you have the data all on the way, it is a simple query to find
one record, and you interpolate along the geometry. I'm not sure how you
would write an effective geocoding engine directly based on the model with
nodes - I think you would need to write some additional that traced the
network and created a new data structure similar to what you would have in
the case with attributes on the road. So it seems to me simpler to just
create and maintain that data structure directly.

In terms of how to decide what number you use when you split a way, you have
the same problem in either case (whether you have nodes at the beginning and
end of the way, or an attribute range). The most obvious approach is to
interpolate based on distance, which is what geocoding engines using address
ranges do - this would give you the same geocoding results before and after.
If you specifically know the street numbers either side of the split then
you can enter those instead.

Cheers,
Peter.

 If you're adding the nodes manually, it's reasonable - you'd want the

 intersection.

 If you're adding things automatically, I guess I have to admit it's a
 little messy - much less than adding two ways, but yeah, it's a bit
 artificial (you could always add a second node in the same exact
 location as the intersection, but only connected to one way, but let's
 not go there).

 Alternatively, you could use a relation, to specify which way you're
 talking about.  From a technical standpoint I guess that's better, but
 people don't like relations.

  So my gut feel is that the simplest approach is still attributes on the
 street.

 How do you split a way?  Do you just guess at the address at the point
 of the split?  Isn't that even more messy?

Peter, I have to challenge you on this.  *Some* TIGER data needs quite
a bit of cleanup.  *Some* TIGER data is already in good shape, and the
only fixes needed are 1) joining at county borders and 2) unjoining at
bridges.  Just for grins, I looked at Ogdensburg, NY.  Been there a
few dozen times and hadn't done any editing (uploading as I send
this).

Frankly, I see very little that needs correcting, and all the usual
stuff that needs to be added ... which would need to be added without
the TIGER data.  Like footpaths, buildings, POIs.

So yeah, a lot of work above and beyond TIGER.  It's not like there's
a shortage of improvements.  It's ridiculous to claim that the TIGER
import has caused anybody to not edit.  If it has, then we've failed
to explain exactly how wonderful OSM can look when it's fully
populated.

  I signed up for the USA 'conversion team' with the express intention
  of challenging the use of the Karlsruhe schema.

Anthony, what is your design?  How is it better than Karlsruhe?  Is it
in the wiki yet, so the rest of us can see it?

Russ, I think you misunderstood my comment. I am in the TIGER import is a
good thing camp. But in the areas I have worked in it has needed a fair bit
of minor positional cleanup. My point is that in those cases where you need
to graphically adjust a street, I don't want to have to edit three or more
ways because there are additional address ways on either side of the street.
