[Talk-us] Fixing road network in New York — MapRoulette challenge #2

[Ilya Zverev]

Hi everyone,

First, thank you for completing the last road graph challenge! The number of 
daily matching errors is twice as low, with almost no important breaks. I 
re-run the next million traces against the validator, and the total number of 
errors for these is 4.6k — compared to 12k before the challenge was published.

I have made the second challenge — with the same parameters there were only 50 
tasks (instead of 260 last time), so I lowered the filtering threshold to get 
93. It’s likely some of them are false-positives. But thanks to Jason’s idea, 
now you can verify each error with OSRM and Mapillary, links to which are 
included in instructions. Please help completing it:

https://maproulette.org/mr3/challenge/3625 


We’re close to fixing most, if not all, oneway-related errors in NYC. Next week 
we (Juno) are launching in New Jersey, so hopefully in a month I’ll be back 
with a challenge for that state. Or even earlier, if the number of errors is 
higher that we expect.

Andy, you are not quite correct about the source of these road errors. Almost 
all have been indeed sitting there for years, unnoticed. When there is a 
changeset introducing errors, we notice and fix it the next morning, since the 
same validator used for making this challenge is run every night here.

If you are curious, this is a page we got from the validator today:

Thanks and have fun editing the map,

[Talk-us] Fixing road network in New York — MapRoulette challenge

[Ilya Zverev]

Hi folks,

I work in Juno, an uber-like company operating in New York City only. We use 
OpenStreetMap data for many things internally, including tolls and map 
matching. And I thought I might use the data we have to help the project.

Yesterday I took ~1 mln rides we made in December and matched them to the OSM 
road network. With that I found a few hundred points where an actual trace 
diverged from the matched one quite often. This usually means a oneway tag is 
wrong, or a turn restriction is incomplete.

The result is this MapRoulette challenge: 
https://maproulette.org/mr3/challenge/3570 


If you know conditional restrictions and how to use Mapillary and other source 
to cross-check data, please help us fix errors in the NYC map. I assume you 
know how MapRoulette works, and there is a short description in the sidebar.

There will be more news to follow. I talked about this at a FOSDEM last week, 
so you might find the recording interesting: https://youtu.be/QR4P3p8eKho 


Have fun,

Handing out business cards is a great idea, which we in Russia have used 
numerous times. This usually directs a conversation towards mapping and 
its benefit for people, which is always good. You should not hide when 
mapping: educating people about OSM is an important part of surveying.


You can find a few design examples on our wiki:

It'd be great to have smaller, shorter versions that could be handed

business owners are curious and law enforcement or other interested
parties might express concern.

I picked business cards because people are familiar with them, they are 
easy to carry and not that expensive.


Having information on both sides, which I don't do, would allow us to 
include tips to help owners add info to OSM. Anyone want to take a stab 
at creating one?

Re: [Talk-us] how can we fix anonymous spam comments

[Ilya Zverev]

To me, anonymous comments to existing notes bear no value. But people are 
divided on that.

Re: [Talk-us] Walmart Import

[Ilya Zverev]

Hi Peter,

Thank you for the extended example of opening_hours containing holidays 
exceptions. While validating the Walmart import, I've encountered a couple of 
these, albeit simpler.

My opinion on tags does not have an extra weight in relation to other mappers. 
With the introduction of the "Conflation Audit" website, to which I link, the 
data owner does not dictate which tags to overwrite as well. By participating 
in validation, you choose which tags to keep and which to override, and where 
to place imported points.

For example, when seeing "24/7; Dec 25 off" on a Walmart, I clicked on that 
line, so it doesn't get overwritten on import. The line becomes highlighted, 
which means that's what will be in OSM after the import. See for an example 
this object:

http://audit.osmz.ru/browse/walmart/4404

Sorry I didn't get to answer earlier,
Ilya

[Talk-us] Walmart Import

[Ilya Zverev]

Hi,

As some of you know, Brandify company wants to import all the Walmart 
locations in the US into OpenStreetMap. They have full permission to do 
that. See the message from their VP Product, Damian, for more detailed 
explanation:


https://lists.openstreetmap.org/pipermail/imports/2017-December/005279.html

After a brief discussion on the imports@ list, they made a few proposed 
changes, and I re-uploaded the result to my imports validation website. 
Could you please look through a couple dozen points, to ensure they will 
be added to correct locations with correct tags? The more the better — I 
plan to to a few hundred myself:


http://audit.osmz.ru/project/walmart

I really hope we can finish this before the New Year.

Thanks,
Ilya
