Re: [OSM-talk] OSM TIGER-based map quality

Dave,

>From what I've seen, yes. Or at least for Santa Clara County,
California. To bolster this, the main "edge" files do not contain street
address ranges in the 2007 data, but the US Census Bureau gives as one
of the two possible options of adding this information to the file is
taking the address ranges from the 2006 TIGER/Line data by matching on
the tlid field. A pretty good indication that the tlid fields match.

Dave,

Not all counties have been improved through the MAF/TIGER Accuracy
Improvement Project (MTAIP). Here is a link to the counties that have
not been improved in the 2007 TIGER data:

Re: [OSM-talk] virtual san francisco mapping party?

2008-04-12 Thread Dan Putler
They are actually the old Cargill Salt Corporation salt evaporation
ponds. The water in these ponds is many times saltier than sea water,
the pink to red color is due to brine shrimp and microbes that live in
these ponds. There is a massive restoration project just underway that
will restore this area to the original tidal marshes that were there.
The upshot for tagging is that they are water, but they are man made,
and in a number of years they will disappear.

To get the full story on this, here are a couple of sites:

On a "ground truth" note, it turns out that state "highways" in
California do range from freeways (CA 85), to major urban surface roads
(CA 82) to narrow two-lane rural roads (CA 130). While "lowly", some of

[OSM-talk] Are there any ways with street number ranges in the OSM database?

2008-12-08 Thread Dan Putler
Hi all,

I'm actually posting as a member of the Postal Address Geo-Coder, or
PAGC, project (www.pagcgeo.org). We have recently developed a web based
postal geocoder service, and are looking to setup a demo site. The site
will have publicly available US TIGER and Canadian StatsCan RNF data,
but we were hoping to use data for an area outside of North America. The
natural choice for this is OSM data. However, PAGC works best if there
are house number ranges along ways. My understanding (which may not be
correct) is that the development of a house number range tagging scheme
is something of an open issue at this point, but based on a thread from
April on this list ("house number revisited", started by Martijn van
Exel) some people have been tagging ways. If there are areas with tags
with house number ranges, we'd like to have some idea of where they are
located. PAGC is currently shapefile centric (though this will change in
the longer run), so we would need to convert the ways to shapefile
format to use them.

Thanks in advance.

Dan

2008-12-09 Thread Dan Putler
Hi Jochen, Christoph, and Maarten,

Thanks for the detailed and complete discussion of the current state of
house number addressing in OSM, it was very useful. Given the related,
and very active, "addressing" thread, it sounds like several issues need
to be ironed out before there is a "final" OSM addressing scheme. From a
practical point of view, it should be possible to do street intersection
geocoding using OSM data as it currently exists, but the use of OSM data
for other forms of geocoding is a work in progress.

Re: [OSM-talk] Are there any ways with street number ranges in the OSM database?

2008-12-10 Thread Dan Putler
Hi Jochen,

The purpose for my inquiry on this topic was to see if there was an area
that has been extensively addressed, and could be used for the
demonstration site we are trying to develop for PAGC. Based on the
thread, it appears the Karlsruhe is the most extensively addressed area
at this point, but only a fairly small proportion of it has been
addressed at this point, too small a proportion to be used for the PAGC
demonstration site at this moment (this will likely change in the future
as more of the city is addressed). This was really the upshot of my
comment about using OSM for geocoding being a work in progress.

As I know you are aware, postal addresses are very messy things, that
differ from country to country (and even jurisdiction to jurisdiction in
some cases). As a result, I think you are correct that a one size fits
all tagging scheme will never be developed (or would even be desirable).
Having said this, from a data user point of view, keeping the number of
different schemes to the minimal acceptable number really makes life
easier.

Hi Jochen,

Thanks for this. When I first posted I had in mind ways with address
ranges (I've got the North American public road network file mindset),
but we can also have a point address geocoder embedded within PAGC as
well, so Prague looks like a good potential solution to our needs.

improve anything, it just makes it harder to associate the data from
the source.

Also, in the case of image tracing, one is recommended to mention a
source= tag. Not everyone does that all the time (I don't do it often,
when I should), but the idea there is the same- to illustrate the data

[OSM-talk] Fwd: Re: Street Addresses

2011-01-29 Thread Dan Putler

Hi John,

You can get New York tax parcel maps inexpensively ($300 per Borough)
and information needed to link it to addresses for free (I don't know if
the licensing is consistent with OSM). My guess is www.ridethecity.com
has licensed the parcel data and has created address points from it. The
city may approve the creation of an address point layer based on this
information that would work with OSM, but then again, maybe not. Here is
the relevant link to the data:
http://www.nyc.gov/html/dcp/html/bytes/applbyte.shtml

Lots of the municipalities in the GVRD have released their parcel maps,
some which may include addresses, but not others. As part of its
"Property Information Package" the City of Vancouver provides address
data (with duplicate addresses removed) that appear to be assessor
parcel centroids. I don't know what the thinking is about the
consistency of the City of Vancouver's licensing with OSM, but it may
well be consistent. The link to this data is:
http://data.vancouver.ca/datacatalogue/index.htm

The general issue in terms of importing address points is that the data
generally comes from local governments (generally cities in Canada and
counties in the US), and local governments differ widely in their data
availability, data field formats, licensing, and basic availability.

 So I'm trying to figure out the street address thing.  Some POI's have

 POI's/Building have address data (US Wide) and I suspect Europe isn't
 much further ahead (10%?)

 Some cities have addr:interpolation.  Toronto is an amazing example
 (thanks CanVec and the people who imported the data):
 http://osm.org/go/ZX6DTTVf9--

 So I was looking at http://www.ridethecity.com/ .  They seem to have
 street addresses for New York and Vancouver, cities that seem to have
 poor address info in the main data.

 Am I missing something?  Is there another file besides the plant.osm
 that has addresses?

 Thanks for the info.

Re: [OSM-talk] Street Addresses

2011-01-29 Thread Dan Putler

Hi John,

The recently released 2010 TIGER/Line data should have better address 
range information than earlier versions. The US Census Bureau went 
throughout the country with GPS units and collected a national set of 
address points to create its Master Address File (MAF) used implementing 
the 2010 Census. They can't release the MAF for non-disclosure reasons, 
and TIGER/Line data has missing address ranges and "random" address 
ranges (where in some cases they have lengthened or shortened the actual 
ranges) for non-disclosure reasons as well. My guess is importing 2010 
TIGER data for NYC would be a nightmare because of the possibility of 
stepping on user edits in OSM. Given the problems with updating road 
ways, I think the real solution for addresses in OSM is to use address 
points where possible.

I believe the US tiger dataset also has street address information and I

definitely higher quality, but I only need 90% quality, not near %100.

There are some great data source on the NYC web age.

I've heard varying opinions of the compatibility of the license between
what Vancouver gives away and the OSM.  I was under the impression it
wasn't cool (the cities license required more attribution than OSM could
provide) but I noticed that people have imported the cities data (all
the building outlines in kits).

Thanks again!

So I'm trying to figure out the street address thing.  Some POI's have
street addresses.  Some nodes in buildings have street addresses.  Some
cities have more address data (Paris and Denver come to mind), some have
nearly none (New York).  If I had to guess I would say less than 1% of
POI's/Building have address data (US Wide) and I suspect Europe isn't
much further ahead (10%?)

Some cities have addr:interpolation.  Toronto is an amazing example
(thanks CanVec and the people who imported the data):
http://osm.org/go/ZX6DTTVf9--

So I was looking at http://www.ridethecity.com/ .  They seem to have
street addresses for New York and Vancouver, cities that seem to have
poor address info in the main data.

Am I missing something?  Is there another file besides the plant.osm
that has addresses?

Thanks for the info.

John

Hi Richard,

Are you aware if they have a terms of use for these services? I can't 
find any on the link you sent, or on the MapQuest Open Platform Web 
Services page. I have an academic research project that this is perfect 
for, but I don't want to abuse my privileges. :-)

Imagine a salesman, who has to visit 10 locations. Is there some

and shortest way?.

Any pointers?.

This is called the "traveling salesman" problem. ;-)  Have a look at the wiki:

and the service built on OSM data at MapQuest

Hi Ant and Richard,

Thanks for the information. This isn't actually going into a we based 
service. It is is based on data I have on people's trips, so I can 
easily adjust the number of requests I send in a day so as to keep it at 
its current resource use level.

Re: [OSM-talk] ArcGIS Online with OSM - Violation of License?

2011-02-24 Thread Dan Putler
Yep, OSM data that needs attribution. The blog entry indicates that OSM 
is the data source, so the attribution there is correct. While this is 
off topic, I will say that I was really impressed by the ESRI JS toolkit 
(liked the scale bar), and how snappy the response is. It appears the 
main thing the toolkit needs is to make it easier to give proper OSM 
attribution.

I recently saw a blog post about how one can embed maps from
ArcGIS.com and that they have an OSM layer.  What jumped out at me is
that even though they manage to get the 'Powered by ESRI' text on the
map, there is no attribution for OSM.  I realize that this may be the
responsibility of the person who created the map on this site, but I
don't really see how one could do that.
