Re: [Talk-in] Use MapRoulette to improve OSM - India data

[Srihari Thalla]

I have completed identifying unmapped villages in Krishna. There are 1174
nodes and ways tagged with "place=village".

I have made a Challenge in MapRoulette to trace roads and connect these
villages with nearby highways. (We can trace houses later.)

I need help with tagging the roads. I made the instructions to tag
asphalt/good condition roads as "tertiary" and other non-asphalt roads as
"unclassified".
Since these roads connect villages with other major highways/town/other
villages, the tags tertiary/unclassified seemed optimal.

Identifying and tagging these unmapped villages took around 8 hours and
spread across a week!
At this rate, it might take several months for me to just tag Andhra
Pradesh and Telangana.

I would really need help from others speeding this up. If anyone's
interested, we can organise and work together.

Re: [Talk-in] Use MapRoulette to improve OSM - India data

[Srihari Thalla]

Hi Deepak,

Thanks for your feedback! It's very useful.

1. I have made a post with detailed instructions for tagging districts. I
think it is a little easy to tag all the adjacent districts as they share
the same ways.
https://lists.openstreetmap.org/pipermail/maproulette/2017-March/000113.html

2. The official railway link for station codes seems to be down sometimes
and working sometimes. I found an IRFCA link to search for the station
codes. I have updated the link in MapRoulette too.
IRFCA - http://irfca.org/apps/station_codes

3. If no Wiki info if found, it's better to leave them and mark as "Too
difficult/Couldn't fix" in MapRoulette. We can investigate them once the
current Challenges are completed.

4. Stations in the middle of nowhere can be left as marked as "Too
difficult". We can check them later! You can find the train routes info at
http://indiarailinfo.com/

Clarifying the last question,

There are a number of stations that are unnamed. I can find the nearest 
town, but don't know where to find lists of stations on some route 
through the town.

Hey Srihari,

I found the challenges a lot of fun. Some feedback below

1. The districts are a little confusing because district borders are
shared between two districts. I guess participants are expected to
select the appropriate way and link to the appropriate wikipedia page.
Would be good to clarify that.

2. www.indianrail.gov.in/stn_Code.html does not open. I've been
searching on DuckDuckGoto find the station code so far.

3. What about towns/cities/districts/railway-stations that have no
wikipedia page? Do I say "I fixed it" without changing anything?

4. Some of the railway stations appear to be in the middle of "nowhere".
Do you have any suggestions on how to find their name?

Hi, Deepak!

You have to zoom in a little bit. MapRoulette is trying to load the

For districts, as they are relations, zoom in on the boundary. This will
make sure that JOSM download contains the relation.
Before (MapRoulette says too much area)

Re: [Talk-in] Use MapRoulette to improve OSM - India data

[Deepak Cherian]

Hey Srihari,

I found the challenges a lot of fun. Some feedback below

1. The districts are a little confusing because district borders are 
shared between two districts. I guess participants are expected to 
select the appropriate way and link to the appropriate wikipedia page. 
Would be good to clarify that.


2. www.indianrail.gov.in/stn_Code.html does not open. I've been 
searching on DuckDuckGoto find the station code so far.


3. What about towns/cities/districts/railway-stations that have no 
wikipedia page? Do I say "I fixed it" without changing anything?


4. Some of the railway stations appear to be in the middle of "nowhere". 
Do you have any suggestions on how to find their name?

Re: [Talk-in] Use MapRoulette to improve OSM - India data

[Srihari Thalla]

I have added "place=village" nodes for villages in Krishna district (AP)
traced on Bing imagery [1] [2]. I have only traced some parts of the
district and the villages count grew to ~700 and probably doubles once I
sweep thru the entire district. It took a couple of hours for mapping them
(~350 in 2 changesets).

At this rate, it would take several days to just identify unmapped villages
and then map them and several weeks to trace roads to them!

Any ideas on how we can speed this up? As Arun said, we should do it in
sprints for this process to take off.

Thoughts and ideas...

Doing via script is good.

Districts and NHs are relations.
We may have to update the script,which Srikanth has shared.

Would it be easier to run through scripts to update the tags? Since these
are far more structured pieces of info to which just a key,value pair needs
to be added, would it be easier to use something like google sheets +
python which I have been using to upload manually verified translations?
The script[1] currently supports addition of k,v pair for name:ta to nodes
and ways, given a csv. Can be easily modified to add wikidata tags.
Thoughts?

Re: [Talk-in] Use MapRoulette to improve OSM - India data

[Srihari Thalla]

I have set up these challenges as of today:

[1] - Railway Station codes
[2] - Wiki tags for railway stations
[3] - Wiki tags for cities and towns
[4] - Wiki tags for districts

-

@Naveen I hope all the NHs are already traced and mapped [and updated to
the new numbering]? I'll check if Overpass QL supports regex tomorrow and
set up the challenges. I might need your help.

-

Regarding tracing roads and building in small towns and villages, I noticed
that more 50% of the villages were not even mapped (at least in
Andhra/Telangana, I didn't look at other states). I think this procedure
might be good:

[a] - Place `node`s with place=village tags for untagged villages. We don't
know all the names, so we might want to leave the name for now.
[b] - Setup challenges to trace roads; and buildings
[c] - Work to get data about the villages (starting with their names
themselves)

I can start [a] with Andhra Pradesh and Telangana
district-wise-alphabetically. If you are open to this idea, let me know and
your thoughts.

-

Here are the links for the Challenges [1,2,3,4]:

[1] - Railway Station codes - http://maproulette.org/map/2403
[2] - Wiki for Railway Stations - http://maproulette.org/map/2404
[3] - Wiki for cities and towns - http://maproulette.org/map/2405
[4] - Wiki for districts - http://maproulette.org/map/2406

cc Arun. Need your help spreading the word :)
-

I am in touch with Martijn of MapRoulette. He said he would feature our
challenges in the upcoming newsletter. I think the challenges above are
pretty easy and useful for getting people from other communities interested
in OSM, as Arun said.

But tracing untraced villages would be good for featuring in his
newsletter. That might bring attention. What do you think?

Re: [Talk-in] Use MapRoulette to improve OSM - India data

[Arun Ganesh]

Challenge 3 and 4 could be quite interesting to get other communities
interested in OSM.

For Wikidata matching, we can share the challenge with the Wikimedia India
chapter. Adding these tags also help make maps on Wikipedia. See Naveens'
diary http://www.openstreetmap.org/user/naveenpf/diary/40515

For any railway mapping we can spread the word on IRFCA, which would get
the railfans really excited.

Srihari, if you can make the challenges, I could help spread the word. We
could also do mapping sprints to map them together with others to knock it
off.

[Talk-in] Use MapRoulette to improve OSM - India data

[Srihari Thalla]

Hi!

Since JOSM featured MapRoulette since a couple of days, there has been a
spike in MapRoulette usage:

   1. All Challenges metrics - http://maproulette.org/ui/metrics
   2. Self-intersecting multipolygon relations (India) -
   http://maproulette.org/ui/metrics/2380

I think we can use this time to add more Indian specific challenges and
thereby improve OSM-India data!

I'm thinking of these challenges:

   1. Reverse ways with oneway = -1 (except in rare cases where direction
   of the way cannot be changed or for other reason) -
   http://overpass-turbo.eu/s/nvV
   2. Trace ___ in small towns and villages
  1. Roads
  2. Buildings
   3. Wikipedia and Wikidata tags for:
   1. Cities and towns - http://overpass-turbo.eu/s/nvT
  2. Railway Stations - http://overpass-turbo.eu/s/nvU
   4. Tag railway station `ref` codes
  1. http://overpass-turbo.eu/s/nvR
  2. Source - http://www.indianrail.gov.in/stn_Code.html
  5. Clean horse=yes tags on highways (except where horses are
   specifically required like at hill stations) -
   http://overpass-turbo.eu/s/nvW
   Question: Who set this tag for highways in the first place? Looks like
   the tags are copied from Europe?
   6. Clean redundant motor_vehicle=yes tags on major highways (not
   restricted expressways) (not where this tag is explicitly required) -
   http://overpass-turbo.eu/s/nvX

Thoughts? Ideas? Improvements?

Cheers,
Srihari
