[Talk-us] Map roulette challenges - Missing named roads [VA, NJ, NY, MN, SC]

[Oisin Herriott (Insight Global Inc) via Talk-us]

Hi all,

In an effort to make the roads data in OSM more complete in names and coverage, 
the Open Maps team at Microsoft is going through some available open data sets 
published by some of the US State agencies, and analyzing these to find gaps 
where named roads are published in the government data, but absent from OSM.

We're publishing these on Map roulette for the mapping community to investigate 
and edit accordingly. The map roulette challenges focus on the rural areas 
where less attention may be paid rather than the urban areas. The coverage is 
state wide but the published date, and quality differs from place to place. 
Below are the first few out there, so feel free to jump in - the water is fine!

  *   Minnesota: https://maproulette.org/mr3/browse/challenges/3486
  *   New York: https://maproulette.org/mr3/browse/challenges/3489
  *   New Jersey: https://maproulette.org/mr3/browse/challenges/3470
  *   Virginia: https://maproulette.org/mr3/browse/challenges/3490
  *   South Carolina: 
https://maproulette.org/mr3/admin/project/2346/challenge/3487

Each challenge has some more information in the description, and links to the 
data sources being used.

Please give us a shout with any comments, feedback, questions, or concerns!

Thanks all,
Oisin

Any chance that New York State Orthos Online can be added to the image
layers? (iD and JOSM both have it.)  For the most part, it's newer
imagery than the sources that are there. More important, it's 'leaves
off' imagery, and a lot of the roads I've seen so far turn up in this
are at most forest tracks and service ways, hard to see under the
trees in summer.

Hi,

Thanks Kevin for the tip! I have updated the instructions to call out the NYS 
ortho online imagery layer to look at for the NY challenge.

Also, after some more fiddling with the roads dataset for the project, I have 
also reduced number of roads to check and updated the New York challenge here:

New York: https://maproulette.org/mr3/admin/project/2346/challenge/3593

Thanks again for the tip!

I've done some of the MapRoulette items for this project, but frankly
I'm not that good at it. For the stuff nearest me, most of the missing
roads are either too new to show on the orthos (which are updated on a
rolling 4-year cycle) or else are old platted rights-of-way that are
now abandoned. I find that I can't do much with them without
boots-on-the-ground knowledge. I was therefore able definitively to
dismiss a few of them with: "I've been there. There's no road," but
that's been the exception rather than the rule.

Finding that sort of thing in the MapRoulette items that I have taken
on makes me wonder what sort of data quality we'll get out of this
effort. Frankly, I've found TIGER review (and this part of the world
is still very much a TIGER desert!) looks to be more fruitful. I find
the NYSDOT database to be an extremely useful cross-check on names and
purported alignments, though. Many ways shown in TIGER around here
were digitized from pencil sketches of census workers and can be
hundreds of metres from the actual locations, but NYSDOT usually has
its information derived at least crudely from survey data.

But perhaps I'm being too much of a perfectionist.

I did a fair amount and noticed similar things — some of the suggestions 
concern private drives, others are not corroborated by available aerials. But I 
did find a decent ratio of fixable things, and as you go through the tasks, you 
get a better sense of which ones are likely to be fixable. The rest you can 
just mark as too hard or not an issue.

As for TIGER fixing, I was inspired by Mike N’s posting about his TIGER fix up 
effort and figured you can use MapRoulette to do some of it. A comprehensive 
review of TIGER roads is probably best done using his Tasking Manager approach, 
but to review just the ‘main’ roads MapRoulette is quite usable. I created a 
challenge for Utah as a proof of concept and working my way through the tasks: 
https://maproulette.org/mr3/browse/challenges/3610 
 

If you want to help out, great. If you want to recreate this challenge for a 
different area, let me know. The overpass query can easily be adapted.

Re: [Talk-us] Map roulette challenges - Missing named roads [VA, NJ, NY, MN, SC]

[Charlotte Wolter]

Martijn and everyone,


A couple of years ago I did some research on named driveways that I was seeing 
in Virginia. County GIS officials told me that, in Virginia, any "driveway" 
with three or more residences had to have a name. TIGER had those names. So did 
the county maps.

I know that sometimes TIGER names driveways and private drives with the name of 
the road that goes past that associated residence. Those probably should be 
considered errors. But in Virginia, at least (I don't know about other states), 
named driveways often are correct.

Just something to think about when you're developing the Maproulette challenge.


Best wishes,


Charlotte
