Mapzen provides metro extracts[0] and I used xpath here to get list of
nodes without name:ta. Parsing extracted Chennai osm file (400 MB) consumes
lot of memory. Python experts, please feel free to optimize this code[1] in
better ways.  The list of nodes (I will come to ways, relations soon) is
available here[2].

Offlate, I am facing strange unicode issues with my script which used to
work, but will soon get it fixed. I am thinking of trying TensorFlow or
equivalent ML models to provide translation suggestions, aside from google
translate. Wikidata doesnt help when it comes to street level sadly.

I can use your script to extract the same for Telangana and AP and
hopefully improve Telugu translations here too, thanks! (BTW, I don't know
Python. Wish I could help.)

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

[Srihari Thalla]

Very happy to know that :)

I see that he has also updated NH wiki tags (but with errors, he is
correcting too). @Naveen Can you check if all the NHs are properly tagged
and complete with Wiki-pedia/data? Thanks.

He is also adding Wiki info for cities and towns now.

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

[Srihari Thalla]

I think not all of the NH are listed in the Wikipedia page. I don't see
NH340C, NH544D, etc,. Are these listed some where else?

Firstly, sorry I think I misunderstood your question - you want to make
Tamil maps! That's awesome - my music teacher will be very happy. : )

You can use https://github.com/mapbox/osm-tag-stats with the country
mb-tiles from http://osmlab.github.io/osm-qa-tiles/country.html, with a
filter like `["==", "name:ta", ""]`.

You can then convert the geojson to csv using a converter available online.

Shrini, and Srikanth, if you require a CSV similar to what Srikanth has
generated, I am happy to generate it for you with a link to the node on
OpenStreetMap. But, first I am curious if Arun, or other Mapboxers on the
list, can explain how to make a To-Fix task if we have a CSV - not sure
what attributes the CSV should have. This will make the process of using
the csv to edit the map really easy, instead of adding edits one by one
from a CSV.

Let's make the map better!

Also, the right overpass links for the same would be:
1. Roads having names (`name`), but no Tamil(`name:ta`) names:
http://overpass-turbo.eu/s/o2q
2. Roads having no `name` tag: http://overpass-turbo.eu/s/nZs
